Bundling Git Tasks

[fullben]

I have seen the example for creating a custom Git task, which is something along the lines of:

task cloneSimpleGitByGitTask(type: GitTask) {
  forceDirectory = false//Just directly use the git executable. 
  command = 'clone' //Git Command
  args = ['https://github.com/rcw3bb/simple-git.git', 'C:\\tmp\\simple-git'] //The git command arguments
}

Now, I would like to create a task that executes multiple Git tasks. For example, let's say I wanna do a checkout of some branch named my-branch, do a merge with some other branch called my-other-branch, followed by a push.

I would like to do that in a single Gradle task. What I would like to do would be something along the lines of:

task myGitActions() {
  doLast {
    // checkout impl here
    // merge impl here
    // push impl here
  }
}

Yet, the only option I see is creating a bunch of tasks of the type GitTask, and finally bundle those via an additional task that just depends on all of those tasks.

Am I missing something here? Is there a way of achieving what I'm outlining above with this plugin?
