Jenkins Cloud Foundry plugin is broken

[dris...@gmail.com]

I've run into an issue and since I'm not able to register on the Jenkins site/JIRA (spam registration protection) I'm posting it here, hope that's ok.

We are trying to use the Cloud Foundry staticfile-buildpack with the following Cloud Foundry manifest.yml 

---
applications:
- name: rrn-hasher
  stack: cflinuxfs2
  memory: 64M
  host: rrn-hasher
  buildpack: https://github.com/cloudfoundry/staticfile-buildpack.git

This manifest works perfectly with using the command line CF tool, but using the Jenkins plugin it seems like its not using/reading the "stack property:
 Submodule path 'compile-extensions': checked out 'ce9345a9a6e7b00266194cadd18dbef37e791a7b'
 It looks like you're deploying on a stack (currently set to *lucid64*) that's not supported by this buildpack.

Can anyone post a bug on the issue tracker and/or know the solution to this?
I posted this first on the Bluemix forum, but it seems to be a plugin problem: https://developer.ibm.com/answers/questions/209542/jenkins-cloud-foundry-plugin-fails-for-bluemix/
