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

myeclipse中使用maven插件的時候，運行run as maven build的時候報錯
-Dmaven.multiModuleProjectDirectory system propery is not set. Check $M2_HOME environment variable and mvn script match.

可以設一個環境變數M2_HOME指向你的maven安裝目錄
M2_HOME=D:\Maven\apache-maven-3.3.9
然後在Window->Preference->Java->Installed JREs->Edit
在Default VM arguments中設置
-Dmaven.multiModuleProjectDirectory=$M2_HOME
