I have an Jenkins pipeline task which builds a Maven Project, pushes the jar to cloudfoundry and removes the workspace files after execution.

But in the last time we have lots of failing builds. Everything works as expected, except the cleanUp after the pipeline.

When I try to remove the  folder by hand, everything gets deleted, except the `manifest.yml` file. And I'm not able to delete this file (tried with and without Administrator), Jenkins have to shutdown first.

Sadly I cannot tell you if there was an Update of the plugin which causes this beahaviour, but this seems to be a problem for around 2 weeks.
