If u are getting error like -Dmaven.multiModuleProjectDirectory system propery is not set.
Check $M2_HOME environment variable and mvn script match In eclipse
then go through Window--> Preference --> Java --> Installed JREs --> Edit In the edit Default VM arguments you need to put If you already set the maven home.
-Dmaven.multiModuleProjectDirectory=M2_HOME (For Windows machine)
-Dmaven.multiModuleProjectDirectory=$M2_HOME (For Mac OS X)
myeclipse使用maven插件进行maven install时报错check $m2_home environment variable and mvn script match
