其中，run_java.sh如下：

1 #!/bin/bash

2 java -jar /chai/Monitor.jar &

3 echo $! 

Monitor.jar 为用jfreechart写的能耗时序图代码，打包而成

run.sh如下：

1 #!/bin/bash

2 $1 &

3 echo $!

$1表示传入给run.sh的第一个参数，如 run.sh "echo helloworld"

对于CDT的安装：

解决方法：

1. 下载地址：http://www.eclipse.org/cdt/downloads.php

我下载的是最新版本cdt-master-8.1.2.zip

2. 安装到eclipse上

步骤：Eclipse ->Help -> Install New Software -> 点击ADD添加 -> 名称填写CDT ，地址那里选择Archive，然后选择已下好的cdt-master-8.1.2.zip   -> OK下一步下一步…最后重启Eclipse

 

当要在其他按钮里触发获取项目，或者获取Package Explorer里当前选项时，可以如下：

IStructuredSelection structured =

(IStructuredSelection)PlatformUI.getWorkbench().getActiveWorkbenchWindow()

.getSelectionService().getSelection("org.eclipse.jdt.ui.PackageExplorer");

//或者 "org.eclipse.ui.navigator.ProjectExplorer"

Object selected = structured.getFirstElement();

if(selected instanceof IResource){

    IProject project = ((IResource)selected).getFirstElement();
