*  原因1：

使用Eclipse Maven插件\[Run As\]-\[Maven build\]时并未为其指定goal或phase   
解决方法：   
在pom.xml中找到 `<build>` 节点，在里面加上`<defaultGoal>compile</defaultGoal>`即可

*  原因2：   
    使用Eclipse Maven插件\[Run As\]-\[Maven build\]时多输入了mvn命令   
    ，因为Eclipse Maven插件已经帮你加上了mvn的命令前缀，再手动输出mvn clean install之类的 命令就会变成mvn mvn clean install
