Description Igor Fedorenko

2011-03-30 20:16:15 EDT

Not quite sure what is going on, but I see many exceptions like below when using latest m2e 0.13 and corresponding m2e-tycho on my Tycho development workspace. I see no obvious problems, but should investigate regardless.

Comment 1 Paul Tatavu

org.eclipse.m2e.core.internal.lifecycle.model.PluginExecutionMetadata
was moved to
org.eclipse.m2e.core.internal.lifecyclemapping.model.PluginExecutionMetadata

Probably your workspace has a serialized state from before the move of that class.

My workspace had state generated by a SNAPSHOT/transient m2e version and removing that state made the problem go away. Regular m2e users are not affected.
