<div><br></div><div>Anyway, without more information, it is difficult to say why you are getting that NPE. Have you tried building and running from the command line [2]? Have you tried the same procedure from a second machine? Have you tried cloning the source code from outside Eclipse (e.g. "git clone git://<a href="http://github.com/imagej/imagej.git">github.com/imagej/imagej.git</a>") and then using "File > Import > Existing Maven Projects" on that folder?</div>
