-Dmaven.multiModuleProjectDirectory system propery is not set. Check $M2_HOME environment variable and mvn script match.

maven的clean时报错

　　-Dmaven.multiModuleProjectDirectory system propery is not set. Check $M2_HOME environment variable and mvn script match.

 解决办法

　　1.添加M2_HOME的环境变量

　　2.Preference->Java->Installed JREs->Edit 选择一个jdk,

　　添加  -Dmaven.multiModuleProjectDirectory=$M2_HOME

在去build, clean , install就没有问题了

-Dmaven.multiModuleProjectDirectory system propery is not set. Check $M2_HOME environment variable and mvn script match.
