Some advice for getting useful answers from this mailinglist:

1. Don't choose a subject that has been used several times already.
("[HELP]Failed to execute pipeline." is surprisingly popular.) You
risk your cry for help getting filed in a 2 year old thread in many

2. Explain what you are trying to do. Give us a short example of
the code or configuration that's causing the problem.

3. Give us a meaningful error message. A NullPointerException can
be caused by a million different things. Most likely there's a
stacktrace below this error message, and the bit below "Caused by" 
is especially interesting. In fact, you might want to have a good
look at that yourself before you post here.
