Windows Folder Redirection Causes Exceptions and Prevents Opening Project
-------------------------------------------------------------------------

                 Key: MEVENIDE-645
                 URL: http://jira.codehaus.org/browse/MEVENIDE-645
             Project: mevenide
          Issue Type: Bug
          Components: mevenide-netbeans
    Affects Versions: NB_3.1
         Environment: Windows Vista, JDK 1.6
            Reporter: Karl M. Davis
            Assignee: Milos Kleint


After installing the mevenide-netbeans plugin and restarting Netbeans, the following two exceptions are thrown in the NetBeans IDE upon startup.  In addition, trying to open a Maven 2 project hangs and never completes.

Exception #1:
java.lang.NoClassDefFoundError: Could not initialize class org.codehaus.mevenide.netbeans.embedder.EmbedderFactory

I have found the following workaround:
In netbeans.conf, set netbeans_default_userdir to "C:/Users/karl/.netbeans/6.1" (edit the path, as necessary).  Also, add " -J-Duser.home=C:/Users/karl/.netbeans/6.1" to the end of netbeans_default_options.
