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 $M2_HOME environment variable and mvn script match.
可以设一个环境变量M2_HOME指向你的maven安装目录
M2_HOME=D:\Apps\apache-maven-3.3.1
然后在Window->Preference->Java->Installed JREs->Edit
在Default VM arguments中设置
-Dmaven.multiModuleProjectDirectory=$M2_HOME
