Re: Error during startup on latest code

The prioritizer was moved during the refactoring to enable support for
multiple versions of a given component.  It is possible that your git
repository contains items that are no longer consistent with the
canonical nifi master repo.  Give 'git clean ...' a try with the
appropriate settings for your case.

I just a did a full build on windows with the latest code base and it
came up just fine.

Thanks
