我无法让 Roo 生成必要的 eclipse 配置文件。每当我执行perform eclipse（或任何其他perform命令）时，shell 都会挂起而不会出错，我被迫 ^C 杀死它。我已经查看了日志，没有任何消息存在、错误或其他。我做了一些谷歌搜索，发现这篇文章准确描述了我遇到的问题。
但是，OP 的解决方案是 Maven 安装不正确。我正在运行 OSX 10.8，它默认安装了 maven 3.0。万一出现兼容性问题，我升级到 3.1，结果相同。当我mvn从 Roo 外部的命令行执行时，maven 似乎可以正常执行，但会出现以下错误：

这似乎表明 maven 运行正常，尽管 pom 文件中没有必要的配置。我是 maven 的菜鸟，所以当我没有给它一个目标时，我不确定它应该在那里说什么。显然它仍然有可能安装不正确，我只是不确定我应该寻找什么来证明这种或另一种方式。有什么想法吗？
更新我mvn eclipse:eclipse按照@CodeChimp 的建议运行，它似乎工作正常。它下载了一堆看起来像逻辑依赖的 jar 文件，并以BUILD SUCCESS. 我不知道为什么在另一个没有的情况下有效。
