Git Workflow Maven Plugin

This plugin is not for the Git Flow model of git branching but rather a set of mojo's that are used to orchestrate the Kuali Student Git conversion.

For the Kuali Student conversion the https://github.com/kuali-student/pull-request-processing project was created to store the base plugin setup and associated helper scripts that would be called by the various Jenkins Build Steps.

Mojo's:

IdentifyPullRequestChangesThroughApiMojo

Identifies which top level module has changes and if there are sql changes.

Each module change will cause a properties file named target/$module-changes.dat to be created.

These will contain the PULL_REQUEST_NUMBER and the MODULE variables.

An sql change will cause a properties file named target/sql-changes.dat to be created.

CI can be configured to spawn downstream jobs based on the existense of these files.

ListOpenPullRequestsMojo

For each open pull request where the tip commit does not have completed or pending CI a file is created like:

open-pull-requests.x

Where x is the pull request number.

Within each file are two parameters:

• PULL_REQUEST_NUMBER : the pull request number.
• PULL_REQUEST_COMMIT_ID : the current commit id of the head of the pull request.

The existense of these files can be used to spawn downstream CI jobs to perform pull request processing.

FetchOpenPullRequestsMojo

These variables can be set using the -D operator: git-flow.sourceGithubUser git-flow.sourceGithubRepo git-flow.sourceGithubBranch

Checkout the latest commit on master:

git clone git://some-server.com/repo.git --depth 1 repo

cd repo

mvn org.kuali.maven.plugins.git-workflow-maven-plugin:0.0.9:fetchOpenPullRequests -e -Dgit-flow.sourceGithubUer=user -Dgit-flow.sourceGithubRepo=repo -Dgit-flow.sourceGithubBranch=master -N

This will pull down the pull request branch tips for the open applicable branches.

Applicable if the base branch of the pull request matches the git-flow.sourceGithubBranch string value.

PushGitReferenceMojo

JGit based Mojo that will push a specified refspec to a specified remote.

The credentials come from environment variables.

This mojo can be invoked in a Jenkins shell which will allow pushing a reference into github.

For example: https://github.com/kuali-student/pull-request-processing/blob/master/pull-request-builder/run-manual-impex-process.sh

GithubCommentsMojo

Proof of Concept to list the comments on a pull request.

GithubStatusMojo.java

Proof of Concept to add a pending build status and to list of existing statuses.

IdentifyChangesInGitMojo.java

Proof of concept to compare the file differences between two git tree's.
