加上这一句就好了
-Dmaven.multiModuleProjectDirectory=$M2_HOME
dmaven.multimoduleprojectdirectory system property is not set intellij
我配置了这个就好了
执行第一maven用例出错：Unknown lifecycle phase "complile".
参考这个，把里面的命令挨个执行一次就好

1 .mvn install
2. mvn compiler:compile
3. mvn org.apache.maven.plugins:maven-compiler-plugin:compile
4. mvn org.apache.maven.plugins:maven-compiler-plugin:2.0.2:compile
