Idea中运行SparkCore程序报错问题解决

在运行程序打包过程中，出现如下错误：

[ERROR] Command execution failed.

解决方案：

　　第一步：遇到问题不要慌，不要一上来就去面向百度编程，先仔细阅读错误原因，一步步排查，通过以上错误我们可以看到Maven在打包时发生 Failed to execute goal org.codehaus.mojo:exec-maven-plugin:1.6.0:exec (default-cli) on project TestSpark ，也就是说程序打包不起来，原因也许是插件版本冲突，也有可能是编译报错

　　第二步：先查看是否属于编译报错

　　第三步：查看Build日志信息，找出错误

　　第四步：再次运行程序，发现打包成功（总结：一定要把报错信息翻译出来，阅读一遍，然后找出报错的位置并解决它，而不是马上就 www.baidu.com ）
