Java 需要EclipseIDE插件开发人员帮助：重命名活动编辑器TextEditor的文件资源

从Eclipse中的一个插件中，我绑定了一个组合键，以尝试使用ProjectExplorer重构对话框重命名由TextEditor编辑的文件资源。编辑器是当时处于活动状态的选定视图。到目前为止我还没有成功

如果我将另一个键组合绑定到同一个命令ID，即“org.eclipse.ui.edit.rename”，然后在ProjectExplorer中手动选择文件资源并执行键序列，那么对话框确实会出现。这是否意味着我需要以编程方式关注ProjectExplorer

有谁能给我提供一些建议，告诉我如何通过编程重构/重命名与活动编辑器关联的资源？我不想执行“另存为”，因为这会将更改提交到磁盘，我也不想强制用户执行此操作

以下是处理程序为自定义键绑定命令调用的测试代码

    public Object execute( ExecutionEvent event ) throws ExecutionException
    {
        IWorkbenchWindow window = HandlerUtil.getActiveWorkbenchWindowChecked( event );
        if( window == null ) return null;

        IWorkbenchPage workbench_page = window.getActivePage();
        if( workbench_page == null ) return null;

        IEditorPart active_editor = workbench_page.getActiveEditor();
        if( !( active_editor instanceof ITextEditor ) ) return null;

        // Not used here yet...
        StyledText styled_text = (StyledText)( (ITextEditor)active_editor).getAdapter( Control.class );
        Display display = styled_text.getDisplay();

        switch( event.getCommand().getId() )
        {
            case "test.commands.sampleCommand":
            {
                IViewPart view_part  = workbench_page.findView( "org.eclipse.ui.navigator.ProjectExplorer" );
                if( ( view_part != null ) && ( view_part instanceof ProjectExplorer ) )
                {
                    // Try and select the resource. This does not seem to do anything visually...
                    IPath path = ( (IPathEditorInput)active_editor.getEditorInput() ).getPath();
                    if( path == null ) return null;
                    ( (ISetSelectionTarget)view_part ).selectReveal( new StructuredSelection( path ) );

                    ICommandService command_service = ( (ProjectExplorer)view_part ).getViewSite().getService( ICommandService.class );
                    if( command_service == null ) return null;
                    Command file_rename_command = command_service.getCommand( IWorkbenchCommandConstants.FILE_RENAME );

                    try
                    {
                        // Rename the selected resource.
                        file_rename_command.executeWithChecks( new ExecutionEvent() );
                    }
                    catch( NotDefinedException | NotEnabledException | NotHandledException exception )
                    {
                        log_error( "Did not work :", exception );
                        return null;
                    }

                    log_info( "Success :" + view_part.toString() );
                }

                return null;
            }

            default: return null;
        }
    }

以下是结果调试日志输出

完全不确定，我在eclipse论坛上也问了这个问题。

大多数编辑器不提供重命名处理程序。事实上，编辑器需要添加额外的代码来处理进行重命名的其他事情-您是否检查过编辑器是否确实处理在其他地方进行的重命名？@greg-449，谢谢，是的，这就是我试图完成的，即为编辑器添加重命名功能。但我对整个EclipseIDE体系结构和组件了解不够，无法实现这一点。如果我找不到答案，我将不得不开始挖掘源代码，并以这种方式学习。
