我试图从互联网上安装一个原型，需要执行 mvn maven-dependency-plugin:2.8:copy。由于错误重爱版本，它无法正常工作。我在本地也有一个正确的版本在我的服务器的存储库中。我的 mvn 捆绑到我服务器上的 nexus 上。

怎么了？

错误信息：

试试这个..你应该给出完全限定的名称，即 groupId:artifactId:version

mvn -e org.apache.maven.plugins:maven-dependency-plugin:2.8:copy

如需更多参考，请参阅 Maven 中央回购。

在您的本地存储库中搜索之前，maven 在您的 nexus 工件存储库中搜索此插件，该插件位于：

http://10.8.1.1:8081/nexus/content/groups/public

例外：

Plugin not found in any plugin repository

但没有找到。将工件放在 Nexus 中，maven 会将其下载到您的本地存储库。

我有同样的问题maven-failsafe-plugin。我为插件指定了一个版本（见这个答案）。
