Bug 125526 [IDE] BuildUtilities.java's extractProjects() method does not consider ResourceMapping cases
Eclipse: 3.2M4 Plugin: org.eclipse.ui.ide Class: org\eclipse\ui\internal\ide\actions\BuildUtilities.java Here is a REVISED extractProjects() method which solves the problem (for your consideration) : ///// CODE START /** * Extracts the selected projects from a selection. * * @param selection The selection to analyze * @return The selected projects */ public static IProject[] extractProjects(Object[] selection) { HashSet projects = new HashSet(); for (int i = 0; i < selection.length; i++) { if (selection[i] instanceof IResource) { projects.add(((IResource) selection[i]).getProject()); } else if (selection[i] instanceof IAdaptable) { IAdaptable adaptable = (IAdaptable) selection[i]; IResource resource = (IResource) adaptable.getAdapter(IResource.class); if (resource != null) projects.add(resource.getProject()); } else { //attempt to find resource mapping for selection IAdapterManager am = Platform.getAdapterManager(); ResourceMapping rm =(ResourceMapping)am.getAdapter(selection[i], ResourceMapping.class); if (rm != null) { IProject[] theProjects = rm.getProjects(); for(int j=0;j<theProjects.length;j++){ projects.add(theProjects[j]); } } } } return (IProject[]) projects.toArray(new IProject[projects.size()]); } ///// CODE END
