在我们公司中，我们使用的是本地关系存储库。如果现在尝试使用eclipse项目向导(已安装M2Eclipse 0.12.1)创建一个新的Maven项目，那么我总是会从Nexus收到503错误。

使用集成的构建或将安装作为“运行方式”任务运行，解决“正常” Artifact 的工作都很好。
在解决这个问题之前，我很简短。
欢迎所有想法。
提前Thx

好吧，我到目前为止已经弄清楚了，看来m2eclipse使用的是.m2/settings.xml中指定的代理，但是如果放弃原型(prototype)，它将忽略nonProxyHosts。
我向m2eclipse项目提交了错误报告:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=348893
谢谢。
关于eclipse - m2eclipse无法从关系解析原型(prototype)，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/6264863/
