2.No plugin found for prefix 'jetty' in the current project and in the plugin groups [org.apache.maven.plugins, org.codehaus.mojo] available from the repositories [local (C:\Users\Administrator\.m2\repository), ukmaven (htt
p://uk.maven.org/maven2/)] -> [Help 1]

解决：将启动方式mvn jetty:run 改为 mvn org.eclipse.jetty:jetty-maven-plugin:run

3.接上第二条问题。这样启动后会说我端口号被占用，但是我怎么改还是被占用。

所以将启动方式再改一下mvn org.eclipse.jetty:jetty-maven-plugin:run -Djetty.port=9999 绑定端口号启动
