使用Maven创建基本项目时出错？

Question

我们的机器上有Maven。我们使用的是Maven 2.2.1和CentOS 6.0。当我们使用以下命令创建基础项目时

mvn原型：创建-e-Darch etypeGroupId=com.jivesoftware.maven-Darch etypeartifactId=maven-jive-plugin-ArchetypeVersion=5.0.2-SNAPSHOT-Dgroup pId=com.demo-DartifactId=jiveDemo

我们收到以下错误消息：-

Warning: JAVA_HOME environment variable is not set.

+ Error stacktraces are turned on.

我们的服务器在防火墙后面。它的原因和解决方案是什么？

Answer 1

什么是关于

Warning: JAVA_HOME environment variable is not set.  

这么复杂？这意味着只需将其定义为Java安装。此外，我建议从Maven 3.0.4开始，而不是2.2.1。

除此之外，您还没有配置为使用代理配置来访问maven central。。最好的解决方案是使用存储库管理器。
