Java 自定义Maven插件托管和前缀解析

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。使用指定的全名，它可以正常工作：

mvn com.mjolnirr:maven-plugin:manifest

但当我想通过前缀执行时，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]

我的插件的

看起来我必须在我的存储库中添加一些定义。你能帮我吗

---

ADD我发现maven试图从

org/apache/maven/plugins

下载

maven metadata.xml

。是否可以在项目POM中更改此路径，而不更改maven设置？

默认情况下，只搜索groupId为

org.apache.maven.plugins

的插件

要让Maven搜索插件的其他GroupID，可以在每个用户的settings.xml文件中配置其他插件组，例如：

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

org.mortbay.jetty
org.apache.tomcat.maven

有关这方面的详细信息，请参阅。

Hmm，我使用Maven JavaFX插件，我可以运行

mvn jfx:run

，但没有您提到的groupId。@skayred

jfx:run

对我不起作用。它的组ID肯定没有在

settings.xml

中定义？对我来说也是这样，但是那些家伙在项目中使用了特殊的pom.xml前缀-是的，我是对的-你可以在第一次使用完全指定的名称后使用前缀
