Should i commit eclipse settings

Non-Windows users should in theory check this setting, but the system wide settings are usually not used on non-Windows platforms.

Congratulations, you just have mastered your first project using Git! Use a personal access token PAT as the password. Do not use your normal log-in password for your user account at GitHub! GitHub personal access tokens give you fine-grained control over what the token holder may do.

This is done by assigning "scopes" to tokens. See the GitHub documentation for the details. Find all exercises and the slides here. Follow the exercise 1 to prepare for the Git Tutorial.

Git is built on a few simple and very powerful ideas. Knowing them helps to understand more easily how git works. The Repository or Object Database stores all objects which make up the history of the project. All objects in this database are identified through a secure 20 byte SHA-1 hash of the object content.

This has several advantages:. The object database is stored in the. Objects are either stored as loose objects or in a single-file packed format for efficient storage and transport.

Git provides a built-in trust chain through secure SHA-1 hashes which allows it to verify if objects obtained from a potentially untrusted source are correct and have not been modified since they have been created. If you get the signed tag for e. All of the involved object names can be checked for consistency using the SHA-1 algorithm to ensure the correctness of the project revision and that the entire history can be trusted.

The Git Index is a binary file stored in the. It also contains the SHA-1 object names of blob objects. A branch in Git is a named reference to a commit.

There are two types of branches, namely "Local" and "Remote Tracking" branches which serve different purposes. Whenever a change to a local Repository is committed, a new commit object is created. Without any other means, it would be very difficult to keep track of the changes in the Repository, in particular when other commits are added to the Repository, for example due to an update from the remote Repository or when checking out another commit.

A local branch helps with this task by providing a local name by which the "current" commit can be found. When changes are committed to the local repository, the branch is automatically updated to point to the newly created commit.

In addition, it is possible to add a so-called upstream configuration to a local branch which can be helpful when synchronizing with a remote repository.

Remote tracking branches are created automatically when cloning and fetching from remote repositories. A remote tracking branch in the local repository always corresponds to a local branch in the remote repository. The name of such a branch follows certain conventions. Remote tracking branches can be used for automated creation of upstream configuration for local branches.

The working directory is the directory used to modify files for the next commit. By default it is located one level above the. Making a new commit typically involves the following steps:. You start from a fresh checkout of a branch of a local repository. You want to do some changes and record snapshots of these changes in the repository whenever you reach a state you want to record.

When you first clone a repository, all files in the working directory will be tracked and unmodified since they have been freshly checked out and you haven't started editing them yet. As you edit files, git will recognize they are modified with respect to the last commit. You stage the modified files into the index and then commit the staged changes.

The cycle can then repeat. When setting up Git Repositories with EGit, there are two recommendations for the creation of "productive" as opposed to "playground" Repositories:. The first mistake happens when you specify a workspace folder during cloning or creation of a Repository. Both mistakes will happen when you use the Git Sharing Wizard from an Eclipse project that you have created manually in your workspace without taking precautions the wizard has been fixed in the latest version.

Git Repositories can be created in different ways, for example by cloning from an existing Repository, by creating one from scratch, or by using the EGit Sharing wizard. In any case unless you create a "bare" Repository, but that's not discussed here , the new Repository is essentially a folder on the local hard disk which contains the "working directory" and the metadata folder.

The metadata folder is a dedicated child folder named ". It contains the actual repository i. The metadata folder is totally transparent to the Git client, while the working directory is used to expose the currently checked out Repository content as files for tools and editors.

Typically, if these files are to be used in Eclipse, they must be imported into the Eclipse workspace in one way or another. In order to do so, the easiest way would be to check in. Thus in most cases, the structure of a Repository containing Eclipse projects would look similar to something like this:. You can create a project first and share it afterwards. The Share Project Wizard supports creation of Git repositories see Adding a project to version control.

You may create multiple projects under a common directory and then create a common repository for all projects in one go:. In order to work with the content of a Git repository in the Eclipse workbench, the contained files and folders must be imported as projects. In principle, this import can be done using the generic "New Project" or "Import However, the newly created projects would still have to be shared manually with Git.

The "Import Projects from Git" wizard integrates project import and sharing and also offers some extra convenience.

Before you can continue, you need to add one or several Git repositories to the list. If you already have repositories in the list, this step is optional. The first option is used if you start with a remote repository. The clone operation will copy that repository to your local file system.

To start the Clone Wizard click Clone Upon successful completion of the clone operation, the newly cloned repository appears in the list automatically. The second option is useful if you already have a repository in your local file system, for example because you have cloned it earlier, you created it from scratch or you copied it from somewhere else. Click Add Press Search to trigger a scan for Git repositories contained in this directory.

If Git repositories are found, they will be listed and you can select repositories to add:. You can now select a repository and click Next. On the following wizard page, you will decide how to import projects. This page offers a group with radio buttons that allows you to select a wizard and a directory tree that optionally allows you to select a folder in the working directory.

If this radio button is selected, the wizard will scan the local file system for. This is the most comfortable solution and should be used if. In this case, the directory tree at the bottom is active. You can limit the search for. On the next page, a list of the found projects if any will be shown. This is very similar to the generic Import Existing Projects wizard, but has some additional filtering capabilities:.

When this option is chosen, the generic "New Project" wizard will open. After completion of the "New Project" wizard, the "Import Projects from Git" wizard will resume and assist with sharing the projects you just created.

In this case, the directory tree at the bottom is inactive, as the selection is not relevant for the "New Project" wizard. This option can be helpful when there are neither. If chosen, the wizard will generate a. The result is a "General Project". By default, the newly generated project will point to the working directory of the Repository.

By selecting some folder from the directory tree at the bottom, you can have the project generated for that folder. Click Next to open a simple dialog for entering a name and a directory for the new project:.

Using the Git Clone Wizard you may clone remote repositories using different transport protocols. You can filter the branches by their name by typing using the text control above the list.

Note, however, that branches that have been checked will always be shown in the list, i. On the next page define where you want to store the repository on the local file system and define some initial settings. You can press Finish on this page or press Next if you are working with Gerrit Code Review and you want to configure your repository accordingly.

The Clone wizard of EGit can be extended by other plugins in order to search for repositories on specific backends which host git repositories. Currently such an extension is available for Github and soon will be available for Gerrit. For both you need to install the respective Mylyn connectors.

The Gerrit Mylyn connector extension then will also configure the remote repository for the work with Gerrit. When you have installed such an extension, the Clone wizard opens with a selection page where you can choose between different sources of the repository to clone:. If you are working with a local branch which has a so-called " Upstream Configuration ", the most convenient way for pushing relies on this upstream configuration.

Typically local branches are created based on a remote tracking branch. Since the remote tracking branch is associated with a remote and the remote contains the information required to access the corresponding remote repository, it is possible to automatically create this upstream configuration while creating the local branch see Branching for more information.

When pushing upstream from the local branch, push requires no further parameters and hence can be performed without showing another dialog based on the stored upstream configuration.

There is also an action available in the Git Command Group. Push will then be executed immediately after selecting the action. The upstream push can be configured using the "Configure A configuration dialog will be shown for configuration of push URIs and corresponding branch mappings RefSpecs :. The dialog is divided into three main sections. In the upper part, information about the currently checked out branch and the remote it's following is shown. Usually local branches are created based on a remote tracking branch which auto-configures that the local branch tracks this remote tracking branch.

In this specific example, there is a warning message that there are several branches that use the remote named "origin". This means that changes in the push configuration will affect all these branches, not just the branch shown in the Branch field. Move your mouse over the warning to display these branches in a tooltip. You can also paste a RefSpec from the clipboard into the list. The buttons in the lower button bar allow you to save your changes and do the push immediately, save the changes without fetching, dry-run push without saving the configuration , revert your changes, and Cancel.

Click Next If this is the first time you connect to this repository via ssh you will have to accept the host key of the remote repository. This is a convenient way to declare that you want to map your local branch names to the same branch names on the upstream repository you want to push changes to.

Click Add all tags spec to map local tags to tags in the repository you want to push to. If you want to map local branches to those in the upstream repository in a different way you may define more detailed mapping specifications in the following way.

To delete a ref in the destination repository select the ref to be deleted from the drop-down list Remote ref to delete and click Add Spec. This will create a corresponding entry in the Specifications for push list. Alternatively you may type in the specification for the refs to be deleted, this may also use wildcards. Pushing Delete Ref Specifications will delete the matching Refs in the destination repository.

If you add multiple conflicting Push Ref Specifications they will be marked in red, solve this by removing or editing the conflicting specs. It is also possible to edit the specs in-place in the list Specifications for push.

This will open the Push Confirmation dialog showing a preview which changes will be pushed to the destination repository. If this does not match your expectation click Back and correct your push specs accordingly. Depending on the options you have chosen a push result report dialog is shown. It displays the list of commits which are pushed to the remote. In the box at the bottom the push confirmation message from the remote server is displayed.

In case of any errors you will find the error message from the remote server here. To see the message for a given list entry simply select it in the list.

If you are working with a local branch which has a so-called " Upstream Configuration ", the most convenient way for fetching relies on this upstream configuration. A local branch is typically created based on a remote tracking branch. Since the remote tracking branch is associated with a remote and this remote contains the information required to access the remote repository, it is possible to automatically create this upstream configuration while creating the local branch see Branching for more information.

When fetching from upstream, this persisted configuration can be used to fetch automatically without the need to provide further parameters in a dialog. Fetch will be executed immediately after selecting the action. The upstream fetch can be configured using the "Configure The "Add" button will open a small wizard that helps in the creation of the RefSpecs. The buttons in the lower button bar allow you to save your changes and do the fetch immediately, save the changes without fetching, dry-run fetch without saving the configuration , revert your changes, and Cancel.

This is a convenient way to declare that you want to map the branch names in the upstream repository you want to fetch changes from to the same local branch names. If you want to map branches or tags in the upstream repository to local branches in a different way you may define more detailed mapping specifications in the following way.

If you are working with Gerrit Code Review , EGit allows you to conveniently push and fetch changes to and from the Gerrit servers. The repository clone is configured such that. If a repository cloned from a Gerrit server outside of EGit is used in EGit, the clone may not be set up such that EGit recognizes it as a Gerrit repository. Gerrit operations in EGit will not appear in any menus unless you configure your repository first.

To do that, open the Git Repositories view and browse down to the Remote that represents the Git repository server you want to use and select Gerrit Configuration The dialog also offers a content assist for the Gerrit branch.

The remote tracking branches for the current repository will be shown. Note that this content assist is filtered, so in order to see all proposals, you need to make sure to have the Gerrit Branch field empty before requesting the content assist. Upon clicking Finish , the currently checked out commit will be pushed to the Gerrit branch specified. Also, the URI and Gerrit Branch values will be remembered and suggested again when the dialog is opened again later.

This allows for more flexibility when working with different Gerrit branches in parallel e. When a change has been pushed to Gerrit and the reviewers suggest to make some improvements, a new patch set for the change has to be uploaded. First, edit the commit s :. Then push again to the same branch. Gerrit will detect that you are updating existing changes and will add new patch sets. A dialog will appear that lets you select or enter a URI and a change as well as some additional options:.

Instead of the tedious copy-paste or manual entering of the change ID, the dialog also offers a content assist for the change. The Gerrit Server will be contacted and all available changes will be fetched and shown in a content assist dialog:. The list will be filtered with your input in the change field. After selecting the change in the content assist, the Change field will be filled with the correct information. This will automatically populate the dialog with the values needed to fetch this change.

Gitflow operations will not appear unless the selected repository is configured for Gitflow. To do that, open the context menu on a repository in the Git Repositories view and select Init Git Flow. A dialog will appear that lets you enter a name for the Gitflow branch, adding the correct prefix automatically. Go to the EGit History view, and right-click the commit you want to start the release from.

Label decorations show Git-specific information about resources under Git version control. Text decorations appear on the left or right side of the text label. For files and folders there are the variables "name" , "dirty" and "staged". The "repository" variable displays the name of the repository.

The "branch" variable displays the name of the currently checked out branch. If no branch is checked out, the decoration shows the shortened name of the commit first seven characters followed by ellipsis. If there are several remote branches or tags that have no modification date, then alphabetic sorting is applied and the last one is shown. Example: the checked out commit e49f This results in the space being added only when the status is not empty.

Icon decorations appear on the lower right corner of the icon displayed in front of the label. A summary of the status of all modified tracked files is displayed on the commit dialog. By double clicking a file the changes to be committed will be displayed in a compare dialog. As EGit currently always commits the content of the working tree corresponding to git commit -a on the command line the compare dialog will compare the working tree with the last commit. In daily work you will often want to see the changes between your last commit, the index, and the current working tree.

In order to do so, select a Resource project, folder, or file in the project explorer or navigator and right-click an action under Compare With. To analyze the contents of a specific commit you should use the History View which supports this task much better, see task Inspecting Commits. If you use any of the submenu actions of Compare With on a single file, a compare editor will be shown, otherwise since EGit 3.

In the toolbar of the Synchronize View you can select the Sychronize Model you want to use for presenting the changes you are inspecting. This feature is also available in the Commit dialog. Double clicking on an entry in the Commit dialog opens a compare dialog. Comparison between Index and another commit isn't implemented yet. The difference between the working tree including not committed changes and a branch or tag can be viewed since EGit 3.

The result is filtered for the resources you selected before starting the comparison. If the Git repository contains multiple Eclipse projects it is sufficient to select one project, the Synchronization View will also include all other projects.

Then in the Synchronize Wizard click into the destination column of the repository you want to synchronize and select the Ref you want to compare against. When clicking "Include local uncommitted changes in comparison" also local, not yet staged changes and the already staged changes will be shown in comparison.

It is also possible to compare multiple repositories at once. In this case in the Synchronize Wizard select for each repository the Ref you want to compare against. Instead of using a compare editor you can enable quick diff support and see the changes within the text editor. If you move your mouse over the annotation you see the content of the version you are comparing to:. Per default, the comparison is against the HEAD. There are three menu entries:.

The history view displays the diff in the lower left pane. Selecting a file in the lower right pane shows the diff for this file. The behavior of a double click on a file in the lower right pane depends on the state of the compare mode toggle button. If it's on, a compare editor will be opened which compares the file content in the current commit with the content in the ancestor commit; if it's off, an editor will be opened showing the file content in the current commit.

Modifications to a project under git version control are persisted in the git history through commits. Starting from the state checked out from the git repository modify your project until you have reached a state you are satisfied with and then commit all these changes into the repository as one single commit. Enabled Compute keywords property value. When chosen Subversive computes recursively the keywords' property values for all resources before the 'Set keyword' dialog is shown.

Enabled Use case-insensitive table sorting. Choose if you want to use a case-insensitive sorting. Enabled Show merged revisions When chosen Subversive show revisions, which took part in the merges, while viewing resource history. Tip: There are two ways how to define a location of a branch tag , which is being created: the first option is to trust the plug-in to detect it respecting project structure for repository locations with enabled structure detection and the second one is to let a user to define URL manually.

Option Description Default Trunk Default repository root name for trunk. Enabled Use '. Disabling improves check out performance. Generally I would try to commit a session rather than to discard it if there were significant updates or added projects during a working session.

All comments are welcome! Thu, 06 August Ed Merks Messages: Registered: July It certainly includes information about which projects are in the workspace and their physical locations. If there is a conflict the user should merge it and commit the resource, may be with overriding, if needed. It is strongly recommended to always input sensible commit comment.

The dialog gives the user a warning message if the comment edit stays empty while some changes are made.
