不论我是执行 mvn hpi:run 还是mvn hpi:run -Djetty.port=8083或者mvn package
再或者mvn -DdownloadSources=true eclipse:eclipse 到会报下面的错误信息：
[WARNING] Rule 0: org.apache.maven.plugins.enforcer.RequireMavenVersion failed with message:

已百度千百回，pom应该没有问题，应为我是直接调试的 使用 mvn archetype:generate -Dfilter=io.jenkins.archetypes:plugin 方式生成的。
