Running the JGitFlow library from within Gradle

I recently seen this blog post and thought it would be really cool if I could integrate git flow into my build scripts. Whats great about this is that because this is a java library it was extremely painless to integrate.

With a little effort this could easily be converted into a plugin for Gradle, but here's my example:

	buildscript{
	repositories{
	mavenCentral()
	}
	dependencies{
	classpath 'com.atlassian.jgitflow:jgit-flow-core:0.9'
	}
	}
	import com.atlassian.jgitflow.core.*
	import com.atlassian.jgitflow.core.exception.*
	task initFlow << {
	//your local working copy is now on the develop branch
	JGitFlow flow = JGitFlow.getOrInit(new File("."))
	}
	task releaseStart << {
	JGitFlow flow = JGitFlow.getOrInit(new File("."))
	//try to start our release
	try
	{
	flow.releaseStart("1.0").call()
	}
	catch (ReleaseBranchExistsException e)
	{
	//the release branch already exists, just check it out
	try
	{
	flow.git().checkout().setName(flow.getReleaseBranchPrefix() + "1.0").call()
	}
	catch (JGitFlowGitAPIException e1)
	{
	logger.error("Something went wrong checking out the release branch")
	}
	}
	catch (DirtyWorkingTreeException e)
	{
	logger.error("you have un-committed changes!")
	}
	catch (BranchOutOfDateException e)
	{
	logger.error("your local develop branch is behind the remote, please do a git pull")
	}
	//Note: your local working copy is now on release/1.0
	}
	task releaseFinish << {
	JGitFlow flow = JGitFlow.getOrInit(new File("."))
	//finish the release and push to the origin
	try
	{
	flow.releaseFinish("1.0").setPush(true).call();
	}
	catch (DirtyWorkingTreeException e)
	{
	logger.error("you have un-committed changes!")
	}
	}

This is only a snippet, so not all of the library is shown, but it works very well as a proof of concept.
