部署在Nexus上的自定义Maven插件不能用于本地计算机上的项目,除非该插件安装在本地repo上或设置为依赖项

我开发了一个定制的Maven插件,并将其部署在远程Nexus存储库上(mvn部署)。jar已正确上载pom,如下所示:

<?xml version="1.0" encoding="UTF-8"?> 
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">     <modelVersion>4.0.0</modelVersion>

    <groupId>something</groupId>    
    <artifactId>xxx-maven-plugin</artifactId>
    <version>1.0.0-SNAPSHOT</version>   
    <packaging>maven-plugin</packaging>

jar包含必要的插件。xml文件,使其看起来很好。

我已配置一个项目以使用该插件:

    <plugins>
        <plugin>
            <groupId>something</groupId>
            <artifactId>xxx-maven-plugin</artifactId>
            <version>1.0.0-SNAPSHOT</version>
        </plugin>
        ...

但当我跑的时候 mvn xxx:mygoal 显示此错误:

[ERROR] No plugin found for prefix 'xxx' in the current project and in the plugin groups [org.apache.maven.plugins, org.codehaus.mojo] available from the repositories [local (/Users/myuser/.m2/repository), remote-repo (http://someremoterepo/nexus/content/groups/central/)] -> [Help 1]

唯一可行的方法是将插件作为插件和依赖项添加到项目中:

    ...
        <dependency>
            <groupId>something</groupId>
            <artifactId>xxx-maven-plugin</artifactId>
            <version>1.0.0-SNAPSHOT</version>
        </dependency>
    </dependencies>
    <plugins>
        <plugin>
            <groupId>something</groupId>
            <artifactId>xxx-maven-plugin</artifactId>
            <version>1.0.0-SNAPSHOT</version>
        </plugin>
        ...

现在它确实找到了插件并正确执行它。我做错了什么?我想应该没有必要将它同时定义为插件和依赖项,其他第三方插件没有这个要求。

更新:

我已将此添加到我的设置中。xml文件:

     <pluginGroup>something</pluginGroup>
  </pluginGroups>

现在错误不同了:

[WARNING] The POM for something:xxx-maven-plugin:jar:1.0.0-SNAPSHOT is missing, no dependency information available
[WARNING] Failed to retrieve plugin descriptor for something:xxx-maven-plugin:1.0.0-SNAPSHOT: Plugin something:xxx-maven-plugin:1.0.0-SNAPSHOT or one of its dependencies could not be resolved: Could not find artifact something:xxx-maven-plugin:jar:1.0.0-SNAPSHOT
[WARNING] The POM for something:xxx-maven-plugin:jar:1.0.0-SNAPSHOT is missing, no dependency information available
...
[ERROR] Plugin something:xxx-maven-plugin:1.0.0-SNAPSHOT or one of its dependencies could not be resolved: Could not find artifact something:xxx-maven-plugin:jar:1.0.0-SNAPSHOT -> [Help 1]

它实际上是在回购中。同样,如果我显式地将其添加为依赖项,它也会起作用???

更新2:

使用Nexus GAV搜索界面,我寻找一个带有artifactId spring boot maven插件和打包maven插件的插件,它找到了它。使用包装罐,它也可以找到它。

然后我对我的插件也做了同样的事情,在寻找打包maven插件时,它会找到它,但在使用打包jar时却找不到。

更新3:

在我的本地repo中,有一个maven元数据中心镜像。包含以下内容的xml文件:

<?xml version="1.0" encoding="UTF-8"?>
<metadata>
  <plugins>
    <plugin>
      <name>something</name>
      <prefix>xxx</prefix>
      <artifactId>xxx-maven-plugin</artifactId>
    </plugin>
  </plugins>
</metadata>
