Question

我尝试从互联网安装一个原型，需要执行mvn maven-dependency-plugin：2.8：copy。由于错误重新发布版本，它无法正常工作。我在本地也有一个正确的版本存储库到我的服务器。我的mvn捆绑到我服务器上的nexus。

有什么问题？

错误消息：

mvn -e maven-dependency-plugin:2.8:copy

Answer 1

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

有关更多参考，请参阅maven central repo。

http://search.maven.org/#search|ga|1|maven-dependency-plugin

Answer 2

在您的本地存储库中搜索之前，maven会在您的nexus工件库中搜索此插件，该存储库位于：

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

例外：

Plugin not found in any plugin repository

但未找到。将工件放在Nexus中，maven会将其下载到本地存储库。

Answer 3

我对maven-failsafe-plugin有同样的问题。我为插件指定了一个版本（参见this answer）。
