If Maven Project Configuration->Local Maven Repository is set to "Local to the Executor"
Redeploy Artifacts fails with:
java.lang.NullPointerException
at hudson.maven.local_repo.PerExecutorLocalRepositoryLocator.locate(PerExecutorLocalRepositoryLocator.java:18)
at hudson.maven.MavenUtil.createEmbedder(MavenUtil.java:106)
at hudson.maven.reporters.MavenAbstractArtifactRecord$1.perform(MavenAbstractArtifactRecord.java:224)
at hudson.model.TaskThread.run(TaskThread.java:127)

It would appear that at least one non-executor associated repo would be required.

Workaround is to set Use private Maven repository->Local to workspace for the jobs one wishes to support redeploy.
