I have a Jenkins app running on Cloud Foundry for a POC. Since it's Jenkins it uses a bound service for file persistence.

I had to make a change to the Java Buildpack and would like Jenkins to use the updated buildpack.

I could pull the source for Jenkins from GitHub and push it again with updated references to the new build pack in the manifest.yml file or via a command line option. In theory, the bound file system service's state would remain intact. However, I haven't validated this assumption and have concerns I might loose the state.

I've looked through the client CLI to see if there's a way to explicitly swap buildpacks without another push. However, I didn't see anything.

Is anyone aware of a way to change the buildpack of an existing application without re-pushing it to Cloud Foundry?

After some research I couldn't find anyway to swap the buildpack without a push. I did discover that my bound file system service remained intact and didn't loose any work.

Answer: re-push to change the buildpack.
