Question

我面临一个奇怪的问题。我已在settings.xml中编辑了Maven M2_HOME/conf文件，并希望将这些文件下载到{users.home}/.m2以外的地方。

我已将<localRepository>G:/m2Repo</localRepository>粘贴到settings.xml。

现在当我输入mvn archetype:generate时，我收到以下错误：

可能是什么问题？

Answer 1

如果工件或元数据损坏，就会发生这种情况。尝试删除所有版本的maven-archetype-plugin（包括元数据和pom文件），以清除您的本地存储库。

然后再次执行archetype:generate。

Answer 2

通过在settings.xml中删除localRepository的条目来解决该问题。开始再次生成原型将下载的工件移动到我们想要的地方G：/ m2Repo 再次开始生成工件。现在罐子等会自动下载到新地方

我能想到的问题是我还删除了{users.home} /.m2文件夹这阻止了下载。

Answer 3

我有一个类似的问题。

环境：

`OS`: Mac Seirra 10.12.6.  
`Java version` :1.8.0_144
`Maven` 3.5.4

解决方案：

rm -rf ~/.m2/repository/org/apache/maven/plugins/maven-archetype-plugin/

Answer 4

我的错误是：

（http://mirrors.ibiblio.org/pub/mirrors/maven2）：

在任何插件存储库中找不到插件

解决方案：

1. go to .m2 folder > repository
2. delete all folders inside this 
3. try the following command again:

mvn archetype:generate

Maven无法使用原型：如果本地存储库从.m2更改，则生成
