我正在学习哈德森。我尝试在 Tomcat 7 中部署的 Hudson 3.0.1 中设置一个“Maven3 项目”，然后尝试执行“全新安装”。首先我看到以下警告：
[WARNING]
[WARNING] Some problems were encountered while building the effective model for DummyProject :DummyProject :war:0.0.1-SNAPSHOT
[WARNING] 'build.plugins.plugin.version' for org.codehaus.mojo:tomcat-maven-plugin is missing. @ line 46, column 12
[WARNING]
[WARNING] It is highly recommended to fix these problems because they threaten the stability of your build.
我在 POM 中有这个插件。我不知道为什么会出现这个警告。此警告之后是以下错误：

谁能让我知道这里有什么问题？如果有人会参考一些文件，这些文件也显示了哈德逊的 Maven 就业机会，我将不胜感激。
谢谢
