The following plugin provides functionality available through Pipeline-compatible steps. Read more about how to integrate steps into your Pipeline in the Steps section of the Pipeline Syntax page. For a list of other such plugins, see the Pipeline Steps Reference page.
This is a special step that allows to run checkouts using any configuration options offered by any Pipeline-compatible SCM plugin. To use a concrete SCM implementations, just install the corresponding plugin and check if it is shown in the list below. Then select the SCM to use from the dropdown list and configure it as needed.
Any other specific step to run checkouts like svn or git are simplistic options of this step. In order to integrate with AWS CodePipeline, you must authorize access to the pipeline and its related artifacts. This is the preferred method. In all other cases, you can store AWS credentials in these fields. You might need a proxy host address if you are hosting Jenkins on a private network. You might need a proxy port for your proxy host address if you are hosting Jenkins on a private network.
The proxy port is a number, might be on port , , or , depending on your network protocols and security settings. Specify the branches if you'd like to track a specific branch in a repository. If left blank, all branches will be examined for changes and built. This way the expected branch is unambiguous. When not presented with a full path the plugin will only use the part of the string right of the last slash. If you use a wildcard branch specifier, with a slash e. When running a job, Jenkins will use these credentials to check out the source code for builds.
For Jenkins to do this, it needs credentials with access to the projects and repositories you want it to build from. This extension point in Jenkins is used by many other plugins to control the job to build specific commits. When you activate those plugins, you may see them installing a custom strategy here.
The repository name. In git the repository is always the name of the remote. So if you have specified a repository name in your Git configuration. You need to specify the exact same name here, otherwise no integration will be performed. We do the merge based on this. Specify the paths that you'd like to sparse checkout. This may be used for saving space Think about a reference repository.
Be sure to use a recent version of Git, at least above 1. If given, "git config user. This overrides whatever is in the global settings. Enter the name of the Bitbucket Server project containing the repository you want Jenkins to build from.
To find a project, start typing. If it doesn't appear in the search results, the credentials that you've chosen may not have read access to it and you'll need to provide different credentials. Enter the Bitbucket Server repository you want Jenkins to build from.
To find a repository, start typing. To get Jenkins to build from a personal repository, enter its slug. This is the URL-friendly version of the repository name. Choose the Bitbucket Server instance containing the repository you want Jenkins to build from. If you can't find your instance, check this plugin's configuration and try again.
Choose the location that Jenkins should clone from when running this build. This can be the primary server or a mirror if one is available. To see available mirrors, first choose a Bitbucket Server project and repository. The build quiet period is designed to assist with CVS checkouts by waiting for a specific period of time without commits.
Normally you want the checkout to reflect the time when the quiet period was exited successfully. Select this option if you need to re-enable the legacy behaviour of Jenkins, i. Note: enabling this option can result in the quiet period being defeated especially in those cases where the build is not able to start immediately after exiting the quiet period. The view storage location that will be passed to the -stgloc option. The list of available servers is retrieved using cleartool lsstgloc -view Note that auto is always available.
If checked, instead of creating a view on the current stream, the job will look up the current foundation baselines for the given stream and work in readonly on these baselines. If polling is enabled, the build will be triggered every time a new foundation baseline is detected on the given stream. Contribute data to a global database.
Defined in the Compatibility Action Storage Plugin. Specify the content of the Makefile. Note for distributed build environment, please make sure the path is accessible on remote node s.
Poll changes will not be affected by this setting. You can apply wildcard filter s when detecting changes and copying files. You may want to filter out, e. Note: filters are applied on both sides, source and destination i. Default is ' true '.
When do you want to modify this value? A good example is when you want to just retrieve one branch. The plugin uses a default refspec for its initial fetch, unless the "Advanced Clone Option" is set to honor refspec.
This keeps compatibility with previous behavior, and allows the job definition to decide if the refspec should be honored on initial clone. Multiple refspecs can be entered by separating them with a space character. See the refspec definition in Git user manual for more details. Select the appropriate credential for the Perforce connection. Perforce Credentials are defined in the Jenkins Credentials plugin here. Select the appropriate Perforce workspace behaviour from the list. Not all modes will suit all Jenkins Job build types.
The character set used by Jenkins when syncing files from the Perforce server. This should be set to 'none' unless connected to a Unicode enabled Perforce server.
Specify the name of the Perforce workspace to be used as the Jenkins build workspace. If the workspace does not yet exist, the configuration will be saved in Jenkins; the workspace is created only when it is to be used.
If the workspace exists and you are connected to a Perforce server the auto-text fill should list suitable workspaces; updates are only applied when the workspace is used. Maps files in the depot to files in your client workspace. Defines the files that you want in your client workspace and specifies where you want them to reside. The default view maps all depot files onto the client. See 'p4 help views' for view syntax. A new view takes effect on the next 'p4 sync'. By default all clients are 'writeable', certain clients are short lived and perform long sync and build cycles.
Over time these build clients can fragment the 'db. Setting a type of 'readonly' gives the client its own personal 'db. A 'readonly' client cannot 'edit' or 'submit' files, however for build automation this is not usually a requirement and the performance tradeoff is worth considering if your build automation is causing issues with the 'db. This option requires that an administrator has first configured the 'client.
If it is necessary to submit changes as part of your build, you may specify a 'partitioned' client: like a 'reaonly' client, this type also has a separate 'db. If not specified backup of a writable client defaults to enabled. Specify the name of an existing workspace in Perforce to be used as the Jenkins build workspace. If connected to a Perforce server the auto-text fill should list suitable workspaces.
Specify the full Perforce depot path for the given stream. If connected to a Perforce server the auto-text fill should list possible streams. Jenklin slave nodes must each use a unique Perforce workspace. The format string configures the workspace name by substituting the specified variables: at least one variable must be used. Variables can be taken from the Jenkins Environment or Parameterized builds.
Specify the name of an existing workspace in Perforce used to create or update a Jenkins build workspace. Changes can be filtered to not trigger a build; if all the files within a change match the specified path, the build is filtered.
This is not Perforce syntax. Use of
This books starts with an introduction into distributed version control systems. It continues to describe the basic Git terminology and how you can configure your Git tools. As the book advances you learn how to connect to remote repositories and how to use branches and tags. The book covers merging and rebasing changes and provides all the necessary tips and tricks to use Git.
This article is an attempt at explaining the Git version control system from the bottom up, that is, starting at the most fundamental level moving up from there. This does not sound too easy, and has been attempted multiple times with questionable success. The last commit of this article was actually created with wyag , not git. And all that in exactly lines of very simple Python code.
Write yourself a Git!
The "checkout" command can switch the currently active branch - but it can also be used to restore files. The most common use case for "checkout" is when you want to switch to a different branch , making it the new HEAD branch. Another use case for "checkout" is when you want to restore a historic version of a specific file. Thereby, you can reset single files to earlier revisions - while keeping the rest of the project untouched. The name of a local branch that you want to switch to. By specifying the name of a local branch, you will switch to this branch and make it the current "HEAD" branch. Creates a new local branch and directly switches to it. Creates a new local branch - and sets up an "upstream" configuration.

Repo complements Git by simplifying work across multiple repositories. Optional elements are shown in brackets [ ]. For example, many commands take project-list as an argument. You can specify project-list as a list of names or a list of paths to local source directories for the projects:. This page merely highlights key options.
The following plugin provides functionality available through Pipeline-compatible steps. Read more about how to integrate steps into your Pipeline in the Steps section of the Pipeline Syntax page.

Repo Command Reference
Home html info man. A git repository can support multiple working trees, allowing you to check out more than one branch at a time. With git worktree add a new working tree is associated with the repository.
See gittutorial 7 to get started, then see giteveryday 7 for a useful minimum set of commands. After you mastered the basic concepts, you can come back to this page to learn what commands Git offers. You can learn more about individual Git commands with "git help command". Other options are available to control how the manual page is displayed. See git-help 1 for more information, because git --help This option affects options that expect path name like --git-dir and --work-tree in that their interpretations of the path names would be made relative to the working directory caused by the -C option.
Version Control With Git: Local Operations
If no paths are given, git checkout will also update HEAD to set the specified branch as the current branch. In this case you can use the --track or --no-track options, which will be passed to git branch. As a convenience, --track without -b implies branch creation; see the description of --track below. Local modifications to the files in the working tree are kept, so that the resulting working tree will be the state recorded in the commit plus the local modifications. In this case, the -b and --track options are meaningless and giving either of them results in an error.
Updates files in the working tree to match the version in the index or the specified tree. If no pathspec was given, git checkout will also update HEAD to set the specified branch as the current branch. Specifying -b causes a new branch to be created as if git-branch were called and then checked out.
