我已经编写了自己的自定义Maven插件并将其上传到我的Archiva服务器。它适用于指定的全名：

mvn com.mjolnirr:maven-plugin:manifest

但是当我想通过前缀做到这一点时，它失败了：

mvn mjolnirr:manifest

[ERROR] No plugin found for prefix 'mjolnirr' in the current project and in the plugin groups [org.apache.maven.plugins, org.codehaus.mojo] available from the repositories [local (/home/sk_/.m2/repository), mjolnirr (http://mjolnirr.dyndns.org/archiva/repository/plugins), central (http://repo.maven.apache.org/maven2)] -> [Help 1]

我的插件pom：

看来我必须在我的存储库中添加一些定义。你能帮助我吗？

添加我发现 maven 试图maven-metadata.xml从org/apache/maven/plugins. 是否可以在不更改 Maven 设置的情况下更改项目 POM 中的此路径？

org.apache.maven.plugins默认情况下，只会搜索具有 groupId 的插件。

为了让 Maven 为插件搜索额外的 groupId，可以在每个用户的 settings.xml 文件中配置额外的插件组，例如：

<pluginGroups>
    <pluginGroup>org.mortbay.jetty</pluginGroup>
    <pluginGroup>org.apache.tomcat.maven</pluginGroup>
</pluginGroups>
