RCP File Path von selected File in Package Explorer für RCP Plugin

[javator]

Hallo ich habe folgende Problem ich brauch den absoluten Dateipfad der selektierten Datei im Package Explorer
Das habe ich bisher:

IWorkbenchWindow window =    PlatformUI.getWorkbench().getActiveWorkbenchWindow();
		
ISelectionService service = window.getSelectionService();
		
IStructuredSelection structured = (IStructuredSelection) service.getSelection("org.eclipse.jdt.ui.PackageExplorer");
		
				
IFile file =(IFile) structured.getFirstElement();
		
IPath path = file.getLocation();
		
System.out.println(path.toPortableString());

Aber die wirft folgenden Fehler:

java.lang.ClassCastException: org.eclipse.jdt.internal.core.CompilationUnit incompatible with org.eclipse.core.resources.IFile

Ich hab's so gemacht.

ISelection sel = HandlerUtil.getActiveMenuSelection(event);
IStructuredSelection selection = (IStructuredSelection) sel;
		
if (selection.getFirstElement() instanceof IFile) {
	IFile file = (IFile) selection.getFirstElement();
	IPath path = file.getLocation();
	System.out.println(path.toPortableString());
}
