Bug 137356 [Markers] marker grouping not working as expected via markerSupport
N20060418-0010 The Java tooling now warns when a buildpath references an execution environment for which there is no exact match in the workspace (warning support is in HEAD as of today - org.eclipse.jdt.launching and org.eclipse.jdt.debug.ui plugins). The marker created should be categorized as a buildpath problem with other JDT build path problems. To do this, I create a marker support extension as follows (in jdt.debug.ui). <extension point="org.eclipse.ui.ide.markerSupport"> <markerAttributeGrouping defaultGroupingEntry="org.eclipse.jdt.ui.category.buildpath" markerType="org.eclipse.jdt.launching.jreContainerMarker"/> </extension> My understanding is that this should group all markers of type "org.eclipse.jdt.launching.jreContainerMarker" as buildpath problems. JUI has a corresponding grouping entry: <markerGroupingEntry id="org.eclipse.jdt.ui.category.buildpath" markerGrouping="org.eclipse.jdt.ui.java_marker_category" label="%MarkerCategory.buildpath" priority="100"/> I get the following error in the log: Reference to invalid markerGroupingEntry org.eclipse.jdt.ui.category.buildpath
