GUEST: attempting to open second maven based project.  I already identified this as a problem back in the RC 1 and was hoping you all would have fixed this.  It works fine in beta. Umh... I will probably revert back to using beta again... Its ashame Production release still has this problem...

osmarjunior: error when i try open a maven project.

GUEST: attempting to open new project in project group and nothing loads... very ANNOYING and makes Netbeans unusable!!!!!

Reproduced in NB 7.0 opening https://svn.java.net/svn/project-snowman~svn/trunk in a fresh userdir, but fix of bug #197994 (in the forthcoming 7.0.1) seems to have worked.

The exception reporter only files a bug report once several different users have encountered the problem; apparently this one is rare, or at least the exception aggregator did a poor job of finding duplicates.

Workaround is to correct the parent POMs to not use RELEASE as a plugin version, which is dangerous and which Maven 3 does not support <https://cwiki.apache.org/MAVEN/maven-3x-compatibility-notes.html#Maven3.xCompatibilityNotes-PluginMetaversionResolution>, though in this case it would anyway be better to use the modern java.net repo <http://java.net/projects/maven2-repository/pages/MigrationAndCleanupRelatedDocumentation>.
