这看起来像是pom.xml中的错误。您可能忘了在部分中包含插件的组id，这将使maven假定默认的/automagic组id org.apache.maven.plugins 应该是这样的：
<plugin>
<groupId>org.apache.tomcat.maven</groupId>
<artifactId>tomcat7-maven-plugin</artifactId>
<version>2.2</version>
</plugin>
<build>
<plugins>
<plugin>
<groupId>org.apache.tomcat.maven</groupId>
<artifactId>tomcat7-maven-plugin</artifactId>
...
发布整个POM，以便我们检查。我成功地使用了该插件，根据您的解释，唯一的区别是我运行了Maven 3。我发布了整个POM.xml。我只是不想让帖子过多，但你是对的。起初，POM看起来还可以，但你要求两个插件，用于Tomcat6a
nd 7。我不知道这是否是一个问题，但是-除非有具体的原因-只要选择一个匹配您的服务器版本。这是出于两台机器之间的兼容性原因。我删除了tomcat6，但仍然没有用：它嵌套在pluginManagement标签中，但这应该可以，对吗？但是你是对的，它似乎在错误的组中寻找插件。实际上，你应该简单地删除标签，而不是内容，只是标签。这也许能解决问题，但为什么这是个问题呢？根据maven文档，它适用于从该版本继承的构建。这就是我们要做的。不，你没有真正继承它，因为你仍然需要一个引用pluginManagement元素的普通元素。它只需要包含groupId和artifactId字段，并将引入所有其他信息版本、配置等。。。根据插件管理中的定义。
