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

eclipse中使用maven插件的时候，运行run as maven build的时候报错

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

可以设一个环境变量M2_HOME指向你的maven安装目录

M2_HOME=D:Appsapache-maven-3.3.1

然后在Window->Preference->Java->Installed JREs->Edit

在Default VM arguments中设置

-Dmaven.multiModuleProjectDirectory=$M2_HOME
