Class MergeWithGitSCMExtension

  • All Implemented Interfaces:
    Describable<GitSCMExtension>
    public class MergeWithGitSCMExtension
extends GitSCMExtension
    Similar to PreBuildMerge, but for use from SCMSource implementations that need to specify the exact base branch hash. The hash is specified so that we are not subject to a race condition between the baseHash we think we are merging with and a possibly newer one that was just pushed.

    IMPORTANT This extension is intended for programmatic use only. It must be the last extension in the list of extensions or else some other extension may turn on shallow cloning.

    Since:
    3.5.0

        Description copied from class: GitSCMExtension
        Called after BuildChooser selects the revision to pick for this build, but before

        This allows extensions to select a derived revision (for example by merging another branch into the chosen revision and returning it) or manipulate the state of the working tree (such as running git-clean.) GitSCMExtension.decorateRevisionToBuild(GitSCM, Run, GitClient, TaskListener, Revision, Revision) vs BuildChooser

        BuildChooser and this method are similar in the sense that they both participate in the process of determining what commits to build. So when a plugin wants to control the commit to be built, you have a choice of these two approaches. The rule of the thumb is to ask yourself if your process takes another commit as an input. BuildChooser is suitable when you do not take any commit as a parameter, and need to precisely control what commit to build. For example the gerrit-trigger plugin looks at a specific build parameter, then retrieves that commit from Gerrit and builds that. GitSCMExtension.decorateRevisionToBuild(GitSCM, Run, GitClient, TaskListener, Revision, Revision) is suitable when you accept arbitrary revision as an input and then create some derivative commits and then build that result. The primary example is for speculative merge with another branch (people use this to answer the question of "what happens if I were to integrate this feature branch back to the master branch?")

        Overrides:
        decorateRevisionToBuild in class GitSCMExtension
        Parameters:
        scm - GitSCM object
        build - run context
        git - GitClient object
        listener - build log
        marked - The revision that started this build. (e.g. pre-merge)
        rev - The revision selected for this build.
        Returns:
        The revision selected for this build. Unless you are decorating the given rev, return the value given in the rev parameter.
        Throws:
        IOException - on input or output error
        InterruptedException - when interrupted
        hudson.plugins.git.GitException - on git error
