Groovy Gradle hack for keeping dependsOn execute order.

	// preserve dependency task order for Gradle (put this near the top of your gradle build file)
	// example: task( 'seq-alpha', dependsOn: orderTasks( 'alpha bravo charlie' ) ) << { /* your task code */ }
	// To view task dependency do cmd: gradle tasks --all
	if ( !(project.ext.properties.containsKey("orderTasksCtr")) )
		project.ext.orderTasksCtr = new java.util.concurrent.atomic.AtomicInteger(1000); 
	def cl_createProxyTask = { aTaskName ->
		def ctr         = project.ext.orderTasksCtr.incrementAndGet();
		def newTaskName = "_seq_${ctr}_${aTaskName}";
		def newTask     = project.task( newTaskName );
		newTask.dependsOn << "${aTaskName}";
		def result = newTask;
	}
	''' , ' " [ ] ( ) '''.trim().split().each {
		if (it in aTasks)
			aTasks = aTasks.replace( it, (32 as char).toString() )
	}
	return aTasks.split().collect { cl_createProxyTask(it) };
