如何使用menuContribution在Eclipse的project Explorer中访问所选项目的路径?

因此,无论视图或编辑器中当前的选择是什么,我都有一些代码来获取项目-我知道它不完整,但对大多数人来说应该这样做-希望它能有所帮助:

@Override
public final Object execute(ExecutionEvent event) throws ExecutionException {
    ISelection selection = HandlerUtil.getActiveMenuSelection(event);
    IResource resource = Activator.getSelectedResource(selection);
    IProject project = resource.getProject();
    //do something

    return null;
}

public static IResource getSelectedResource(ISelection selection) {
if (selection instanceof TreeSelection) {
  Object selectedElement = ((TreeSelection) selection).getFirstElement();
  if (selectedElement instanceof IResource) {
    return (IResource) selectedElement;
  } else if (selectedElement instanceof IPackageFragmentRoot) {
    return ((IPackageFragmentRoot) selectedElement).getResource();
  } else if (selectedElement instanceof IJavaProject) {
    return ((IJavaProject) selectedElement).getProject();
  }
} else if (selection instanceof TextSelection) {
  IWorkbenchPage page = PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActivePage();
  IEditorPart editor = page.getActiveEditor();
  if (editor.getEditorInput() instanceof IFileEditorInput fei) {
    return fei.getFile();
  }
}
return null;

}
