How to commit/push a Git tag with Gradle?

I have created a specific Gradle task that should only be called in the Jenkins build system. I need to make this task depend on another one which should tag the HEAD of the master branch after a successful compilation of the project.

I have no idea how can I commit/push/add tags to a specific branch in remote repository using Gradle. What's the easiest way to achieve this?

Any help is really appreciated...

You can use Exec as pointed in above comment or use JGit to push tag. Create a plugin / class in java and use it gradle
