如何设置Maven 3本地插件存储库

问题描述

由于某些限制，我需要拥有一个完全脱机的Maven存储库.根据 http://cwiki.apache.org/confluence/display/MAVEN/PluginResolutionException，仅在<pluginRepositories>中搜索插件.所以我想知道如何配置Maven以在本地文件系统中查找插件.设置<url>时，我尝试使用"file://"前缀，但这不起作用.

I need to have a completely offline maven repository due to some limitations. According to http://cwiki.apache.org/confluence/display/MAVEN/PluginResolutionException , only <pluginRepositories> are searched for plugins. So I am wondering how to configure maven to look up plugins in a local file system. I tried using "file://" prefix when setting <url> but it doesn't work.

The settings.xml

<settings>
<offline>true</offline>
  <profiles>
  <profile>
    <id>local</id>
    <pluginRepositories>
      <pluginRepository>
      <id>central</id>
      <url>file://${env.HOME}/.m2/repository</url>
      <releases>
        <enabled>true</enabled>
      </releases>
      <snapshots>
        <enabled>true</enabled>
      </snapshots>
    </pluginRepository>
  </pluginRepositories>
   </profile>
 </profiles>
<activeProfiles>
  <activeProfile>local</activeProfile>
</activeProfiles>

<localRepository>${env.HOME}/.m2/repository</localRepository>

推荐答案

最后，我发现了问题，在插件目录中有一个名为_maven.repositories的文件，删除该文件后，一切正常！

Finally, I found the problem, there's a file called _maven.repositories in the plugin directory, after I delete the file, all works well!
