Hi all,

I have a working Jenkins job which builds a p2 site and afterwards three
products. These are based on several shared features which are provided by
p2 repositories built by other jobs.

Now I added another feature containing German locale fragments for a number
of plug-ins to the product feature. This leads to the following problem:

init actor: 
copyTargetFragments[org.example.helloworld:osgi.bundle$1.0.0.qualifier#target.fragments.source]
Action 
org.example.helloworld:osgi.bundle$1.0.0.qualifier#target.fragments.source 
using 'up to date' policy ACTOR: Rebuild needed: Actor decision
INFO:  [start 
org.example.helloworld:osgi.bundle$1.0.0.qualifier#target.fragments.source]
  Product alias = action.output
  Product base = ${buckminster.output}/fragments.source/
  buckminster.component=org.example.helloworld
  workspace.root=/var/lib/jenkins/jobs/HelloWorldProduct/workspace
  buckminster.temp=/var/lib/jenkins/jobs/HelloWorldProduct/workspace/buckminster.temp/org.example.helloworld_1.0.0-
osgi.bundle/temp
  fragment.attribute=source.bundle.jar
  buckminster.home=/var/lib/jenkins/jobs/HelloWorldProduct/workspace/refProduct/org.example.helloworld/
  buckminster.output=/var/lib/jenkins/jobs/HelloWorldProduct/workspace/buckminster.output/org.example.helloworld_1.0.0-
osgi.bundle
  generator.buildTimestamp.format=2014-01-17T18:00:15.903+0000
  buckminster.component.type=osgi.bundle
  buckminster.version=1.0.0.qualifier
  org.example.helloworld.unqualified.owner.version=1.0.1
  eclipse.home=/var/.../buckminster-headless
  target.location=/var/lib/jenkins/jobs/HelloWorldProduct/workspace/.buckminster/tp
Doing full workspace refresh

Cancel jobs that are known to run indefinitely...
CANCELED JOB: (org.eclipse.core.internal.resources.DelayedSnapshotJob)

Does anybody have an idea about what could be the problem here?

Hi Axel,

Please report this in a bugzilla. An NPE should always be considered a bug.
