Moin,
if other users want to work with grizzly in eclipse i have an eclipse workspace
lifecycle-mapping-metadata.xml for you which is needed by the maven/m2e plugin.
The mappings just tell m2e to execute the plugins it previously refused to
execute because it didn't know how to handle them.
See
http://wiki.eclipse.org/M2E_plugin_execution_not_covered for more infos.
Best regards,
Marc
