Today I faced the problem with NetBeans: it couldn’t load my plugin I’m developing.
I have a plugin representing a toolbar for IDE. If I do some changes in code and want to run a plugin invocing “Install/Reload in targed platform” command I always get an exception:
Deploying test module C:\jdev\workspace\Simpla\build\cluster\modules\com-sandlex-simpla.jar…
Disabling StandardModule:com.sandlex.simpla jarFile: C:\jdev\workspace\Simpla\build\cluster\modules\com-sandlex-simpla.jar…

and several more exceptions and new IDE instance starts without my plugin loaded and display a dialog with exception:

All you need to get rid of these exceptions is clean and build you project before you start it. It works fine for me if I do it each time I want to run my plugin.
