After we download the Maven3.3.1 and unpack, we first need to put the path into the system environment variables of the computer (1. Create an environment variable m2_home=D:\Apps\ Apache-maven-3.3.1;2. Add an environment variable to the system variable following path:%m2_home%\bin;); second, in window->preference->java->installed JREs- >edit interface, find "Default VM arguments Settings", fill in the following values:-dmaven.multimoduleprojectdirectory= $M 2_home; Finally, click Finish Setup You are running the MAVEN project again, running successfully!!!!
