nicolas de loof commented on MGWT-85:
-------------------------------------
If you have the gwt-maven-plugin open in eclipse as a project, this is a known
limitation of m2celipse to NOT be able to run such plugins (as they are
resolved as project reference by m2eclipse, and this breaks maven)
Simply closing the project will fix this.
If this is not your current layout please ask the m2eclipse user list ;)
