Git Automerger

Build Status

The main purpose of this plugin is to ensure that all newer versions include all the changes from older versions.

Requirements

The plugin is merging only the branches with the following structure:

*  master
|
| * release/2.0
|/
|
| * release/1.5
|/
|
| * release/1.0
|/

The naming of release branches is flexible, but the branch name must contain a version number. Versions are ordered using Apache's ComparableVersion.

Warning: Do not use the plugin if your version system differs from ComparableVersion. The plugin can merge newer package into older.

If you are using a different branch strategy, please fill a feature request.

Conflicts

In many cases merge conflicts can be solved automatically. You could define one of available conflict resolution per file.

For example you have conflict:

release/1.0 release/1.1
Foo Bar

According to selected resolution, one of outcome could be:

KEEP_OLDER KEEP_NEWER MERGE_NEWER_TOP MERGE_OLDER_TOP
Foo Bar Bar
Foo
Foo
Bar

For example, for CHANGELOG.md you would probably prefer to use MERGE_NEWER_TOP

Example:

gitAutomerger logLevel: 'INFO',
              mergeRules: [
                  [path: 'CHANGELOG.md', resolution: 'MERGE_NEWER_TOP'],
                  [path: 'version', resolution: 'KEEP_NEWER'],
              ],
              releaseBranchPattern: 'release/%',
              checkoutFromRemote: true,
              remoteName: 'origin',
              detailConflictReport: true
