Bug 121979 [build path] Should not to be able to edit source folder if project folder
Version: 3.2.0 Build id: I20051220-0800 It's possible to edit a source folder on the project property page for build path even if it is the projects root folder. Doing so results in something like: java.lang.IllegalArgumentException: Path must include project and resource name: /Test08 at org.eclipse.core.runtime.Assert.isLegal(Assert.java:58) at org.eclipse.core.internal.resources.Workspace.newResource(Workspace.java:1552) at org.eclipse.core.internal.resources.Container.getFolder(Container.java:137) at org.eclipse.jdt.internal.ui.wizards.buildpaths.BuildPathsBlock.flush(BuildPathsBlock.java:779) at org.eclipse.jdt.internal.ui.wizards.buildpaths.BuildPathsBlock.configureJavaProject(BuildPathsBlock.java:675) at org.eclipse.jdt.internal.ui.preferences.BuildPathsPropertyPage$1.run(BuildPathsPropertyPage.java:206) at org.eclipse.jdt.internal.core.BatchOperation.executeOperation(BatchOperation.java:39) at org.eclipse.jdt.internal.core.JavaModelOperation.run(JavaModelOperation.java:720) at org.eclipse.core.internal.resources.Workspace.run(Workspace.java:1714) at org.eclipse.jdt.core.JavaCore.run(JavaCore.java:3949) at org.eclipse.jdt.internal.ui.actions.WorkbenchRunnableAdapter.run(WorkbenchRunnableAdapter.java:87) at org.eclipse.jdt.internal.ui.actions.WorkbenchRunnableAdapter$1.run(WorkbenchRunnableAdapter.java:102) at org.eclipse.core.internal.jobs.Worker.run(Worker.java:58)
