This is a Jenkins Build Wrapper for Maven Jobs. It enables you to perform Maven releases using the Apache Maven Unleash Plugin.
That plugin is providing significant advantage for a Maven release process versus the original Maven release plugin like:
- Checking for SNAPSHOT dependencies
- Rolling back previous step transactions - like SCM commits - in case of a release process step failing
- CDI based custom extendable default workflows
See unleash-maven-plugin Wiki for details.
This plugin has recovered from deprecation tagged by 21-Dec-2022 since the Apache Maven Unleash Plugin did continue to be actively maintained. That plugin did move by a new groupId to Maven coordinate io.github.mavenplugins:unleash-maven-plugin.
It is working seamlessly for Maven >= 3.3.9 on Java 8, 11, 17 and 21 since unleash-maven-plugin version 3.0.0.
This section describes the project configuration options as well as the actual usage of the plugin when building Maven releases.
In order to use the plugin for building Maven releases you will have to enable it first in the configuration of your Maven build job. Go to the Build Environment section and enable the build wrapper by checking the Unleash box.
Then you will see some input fields for basic settings. There you can add the required profiles and options for your release build. The goals are pre-defined because currently unleash:perform is the only goals that makes sense there.
Clicking the Advanced... button shows some additional settings for workflow overriding, SCM-related settings and some checkboxes that affect the actual release form that we use later.
The Hook Data section can then be used for really advanced stuff. If you f.i. extend the default workflow and add an exec-hook to the workflow, you will be able to provide data for the hook execution at this point.
The usage of the plugin is pretty simple and is nothing more than submitting a form on a subpage of the project.
After you've enabled the plugin a link will be shown on the left side of the screen called Trigger Unleash Maven Plugin:
After clicking on this link you will be directed to the form page where you can start the release build for your project. 
On this page you can either specify a global version for all modules of the project (for release and dev) or you stick to the versions provided by the plugin and listed in the table which allows independent versioning of modules.
You can also provide custom SCM credentials, override the tag name pattern and/or SCM message prefix or request some other stuff.
Once you have some successful or failed release builds you can also get some project-related release information, such as the badge icons indicating successful or failed releases.
There are also two permalinks available, one for successful and one for failed releases.
Finally there are some ListView columns:

Substantial parts of the plugin sources have been extracted from the M2 Release Plugin. It served as a base for getting started since the feature set was very similar.
