tomcat maven插件启动报错tomcat\conf\tomcat-users.xml cannot be read

报错

[ERROR] Failed to execute goal org.codehaus.mojo:tomcat-maven-plugin:1.1:run (default-cli) on project metaDB: Could not start Tomcat: Memory database file 

D:\WORK\target\tomcat\conf\tomcat-users.xml cannot be read -> [Help 1]

解决：删掉${baseDir}/target/tomcat目录，重新执行命令tomcat:run，搞定。
