Description Igor Fedorenko

2011-09-06 10:17:41 EDT

org.eclipse.m2e.editor has compile/runtime dependency on org.eclipse.ui.workbench, however this dependency is not explicitly listed in editor's bundle manifest. Instead, there is optional dependency on org.eclipse.emf.edit.ui, which just happens to re-export org.eclipse.ui.workbench and few other bundles. As a result, m2e editor fails to open with exception below if org.eclipse.emf.edit.ui bundle is not available




org.eclipse.core.runtime.internal.adaptor.EclipseLazyStarter$TerminatingClassNotFoundException: An error occurred while automatically activating bundle org.eclipse.m2e.editor (227).

Comment 1 Igor Fedorenko

Changed org.eclipse.m2e.editor bundle manifest to explicitly list required bundles. Should be fixed now.
