报错内容
Failed to execute goal org.apache.maven.plugins:maven-help-plugin:2.2:effective-pom (default-cli): Goal requires a project to execute but there is no POM in this directory (C:\Users\LIUSHY). Please verify you invoked Maven from the correct directory. -> [Help 1]
2.解决办法
报错内容是说没有找到pom文件,路径跳转到工程所在路径再次执行mvn help:effective-pom即可;
