我无法执行任何maven命令，这是错误消息：
Child module /root/.jenkins/workspace/testmaven/trunk/Sermicro of /root/.jenkins/workspace/testmaven/trunk/pom.xml does not exist
我使用mvn版本：Apache Maven 3.0.5
The project fr:trunk:1.0.0-SNAPSHOT (/root/.jenkins/workspace/testmaven/trunk/pom.xml) has 1 error [ERROR] Child module /root/.jenkins/workspace/testmaven/trunk/Sermicro of /root/.jenkins/workspace/testmaven/trunk/pom.xml does not exist
