[![Build Status](https://ci.jenkins.io/buildStatus/icon?job=Plugins%2Fgit-automerger-plugin%2Fmaster)](https://ci.jenkins.io/job/Plugins/job/git-automerger-plugin/job/master/)

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](https://github.com/apache/maven/blob/master/maven-artifact/src/main/java/org/apache/maven/artifact/versioning/ComparableVersion.java).

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