本文介绍了一种在Eclipse中创建自定义删除工具的方法，该工具能够删除指定路径下的文件和文件夹，并通过进度条显示删除进度，同时在错误日志中记录删除操作。

在工具栏中添加删除按钮，删除指定文件夹及所有子文件和子文件夹，同时在Error Log视图中显示逐条删除信息。

1、建立plugin工程

2、设置扩展点

extension中Add一个org.eclipse.ui.actionSets

actionSet设置visible为true

actionSet右键new一个action，设置toolbarPath, icon, class

3、进度条

WorkbenchJob、IProgressMonitor

deleteJob = new WorkbenchJob("Delete Test Project") { @Override public IStatus runInUIThread(IProgressMonitor monitor) { try { //设置进度条，length是进度条长度 monitor.beginTask("Task", length); //设置进度条名字 monitor.setTaskName("TaskName"); /*加入逻辑代码 *每执行完一次进度条+1 *monitor.worked(1) *进度条执行任务细节更新 *monitor.setTaskName("TaskDetail"); */ } catch (Exception e) { e.printStackTrace(); } monitor.done(); //返回执行状态 return new Status(IStatus.OK, "com.ibm.cte.jet.test.clean", IStatus.OK, "Test Project delete over.", null); } }; //获取工作间，运行进度条 IWorkbench workbench = (IWorkbench) PlatformUI.getWorkbench(); try { workbench.getProgressService().run(true, false, new IRunnableWithProgress() { @Override public void run(IProgressMonitor monitor) throws InvocationTargetException, InterruptedException { // generate unit test codes deleteJob.runInUIThread(monitor); } }); } catch (InvocationTargetException e1) { e1.printStackTrace(); } catch (InterruptedException e1) { e1.printStackTrace(); }

代码如下：

TestProjectClean.java

package com.ibm.cte.jet.test.clean.popup.actions; import org.eclipse.jface.action.IAction; import org.eclipse.jface.viewers.ISelection; import org.eclipse.ui.IWorkbenchWindow; import org.eclipse.ui.IWorkbenchWindowActionDelegate; import org.eclipse.ui.PartInitException; import org.eclipse.ui.PlatformUI; import com.ibm.cte.jet.test.clean.util.DeleteUtil; public class TestProjectClean implements IWorkbenchWindowActionDelegate { @Override public void dispose() { // TODO Auto-generated method stub } @Override public void init(IWorkbenchWindow window) { // TODO Auto-generated method stub } @Override public void run(IAction action) { // TODO Auto-generated method stub try { // open Error Log view PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActivePage() .showView("org.eclipse.pde.runtime.LogView"); } catch (PartInitException e) { e.printStackTrace(); } String fileDir = "C://ADAT//test//testprojects"; DeleteUtil.delete(fileDir); } @Override public void selectionChanged(IAction action, ISelection selection) { // TODO Auto-generated method stub } }

DeleteUtil.java
