java - 我的类型非法扩展了 DeleteResourceAction

Question

我有一个扩展 DeleteResourceAction 的类型。 Eclipse 给我以下警告:

An anonymous type defined in mishanesterenko.changevisualizer.command.handler.DeleteResourceCommandHandler.execute(ExecutionEvent) illegally extends DeleteResourceAction

出现此警告的原因是什么？

UPD

我有以下生成警告的代码:

DeleteResourceAction deleteAction = new org.eclipse.ui.actions.DeleteResourceAction(new CustomShellProvider(activeWindow)) {
            @Override
            public IStructuredSelection getStructuredSelection() {
                IStructuredSelection selection = (IStructuredSelection) selectionService.getSelection();
                Object element = selection.getFirstElement();
                if (element instanceof CustomProject) {
                    return new StructuredSelection(((CustomProject) element).getProject());
                }
                return selection;
            }
        };

在 DeleteResourceAction javadoc 中有一个不扩展类的明确请求。
