打造定制的Eclipse File System Plugin

 

不知是不是Eclipse的生态策略和用户考虑，没有把MyEclipse那个Open in Explorer的小功能到整合到IDE。很多时候，是需要直接操作文件系统的。没有这个小功能，就只能：文件选中->右键快捷菜单Properties (Alt+Enter)->复制文件路径->Win+R->粘贴回车。这个是在Windows下的。如果经常打开命令行，以当前目录作为命令行的工作目录，还要手动输入CD命令，相当繁琐。于是就有了需求啦。在网上参考资料，最终效果图。为了简化操作，快捷键的必需的。这里我设了Ctrl +`和Ctril+1

 

 

 

代码和设定主要参考了下面的链接：

经过本人的阉割改造，plugin.xml设定如下

事件响应处理Java Code如下，只把关键的获取文件路径的代码保留下来。

 

 

public abstract class AbstractFileSystemResourceAction extends AbstractHandler {

	@Override
	public Object execute(ExecutionEvent event) throws ExecutionException {
		IWorkbenchWindow window = HandlerUtil
			.getActiveWorkbenchWindowChecked(event);
		ISelection selection = window.getSelectionService().getSelection();
		if (selection instanceof IStructuredSelection) {
			Object element = ((IStructuredSelection) selection).getFirstElement();
			IResource resource = null;
			if ((element instanceof IResource)) {
				resource = (IResource) element;
			} else if (element instanceof IAdaptable) {
				resource = (IResource) ((IAdaptable) element)
						.getAdapter(IResource.class);
			} 
			if(resource != null) {
				doExecute(resource.getLocation().toFile());
			}
		}
		return null;
	}
	
	protected abstract void doExecute(File file);
}

 

编写具体执行的Action响应处理，如果不是目录的话，为了不把文件打开，做了特殊的处理。

 

public class OpenWinDirAction extends AbstractFileSystemResourceAction {

	@Override
	protected void doExecute(File file) {
		if (file != null) {
			if(file.isFile()) {
				file = file.getParentFile();
			}
			try {
				Runtime.getRuntime().exec("explorer.exe " + file.getAbsolutePath());
			} catch (IOException e) {
				e.printStackTrace();
			} 
		}
	}
}

 

打开命令行的事件响应处理Action如下。Windows Platform的那条cmd命令有点闹心，折腾许久才把黑色小窗口给弄出来。

 

public class OpenWinCmdAction extends AbstractFileSystemResourceAction {

	@Override
	protected void doExecute(File file) {
		if(file != null) {
			if(file.isFile()) {
				file = file.getParentFile();
			}
			try {
				Runtime.getRuntime().exec("cmd /k start cd /d " + file.getAbsolutePath());
			} catch (IOException e) {
				e.printStackTrace();
			} 
		}

	}
}
