Maven 没有下载插件：jetspeed-unpack-maven-plugin
Maven is not downloading a plugin : jetspeed-unpack-maven-plugin

mvn clean install 和 eclipse:eclipse 都以“成功”结束，但是 jeetspeed 插件什么都不做，我在构建时没有看到他在控制台中做任何事情，他甚至在我的本地也没有存储库。
是的，我在我的 maven conf 文件中添加了 maven central (http://repo1.maven.org/maven2/)
我正在使用 maven 3.2.1
我能做什么？
谢谢

它没有做任何事情，因为您没有将插件的任何执行绑定到生命周期阶段。您需要像这样添加一个块：
