How to coordinate and parallelize between multiple ant tasks and Jenkins

Question

I have this scenario:

I have a Jenkins Job which basically performs the build and followed to that it starts deploying the artifacts into the virtual machines.

Here is my problem. At the moment I deploy artifacts one by one sequentially i.e. via ant task from the same build.xml file.

Deploy and install Artifact 1
Deploy and install Artifact 2
Deploy and install Artifact 3
Deploy and install Artifact 4

Each of these deployments take 30 mins.

So I am interested to know how I can plan to parallelize this.

As the deployment is not that resource intensive I am not interested to use slave Jenkins. So it will probably be a bit overkill.

Answer 1

You'll want four executors on your jenkins master. You can do this by going to manage jenkins > Manage Nodes > Master > Configure, and change the "# of executors" to 4

Then you'll want to split your jenkins job into four jobs - each calling one of your ant targets. The build flow plugin is genius, however you may not need it.
