eclipse+Maven插件报错：-Dmaven.multiModuleProjectDirectory system propery is not set. Check $M2_HOME environment variable and mvn script match.

问题描述：

eclipse indigo+maven3.3.3+jdk1.70

maven插件执行报错：-Dmaven.multiModuleProjectDirectory system propery is not set. Check $M2_HOME environment variable and mvn script match.

解救方法：

1、设置M2_HOME=D:TOOLSMAVEN3.3.3

     可cmd.exe后测试，mvn -version出现版本号后即为设置正确。

2、设置eclipse的java->installed jres->jdk1.70->Default VM arguments:

     -Dmaven.multiModuleProjectDirectory=$M2_HOME
