Question

在我们公司，我们正在使用本地nexus存储库。如果我现在尝试使用eclipse项目向导（安装了M2Eclipse 0.12.1）创建一个新的Maven项目，我总是从nexus得到503错误。

使用集成构建或运行安装作为“run-as”任务，解析'普通'工件可以正常工作。

在解决这个问题之前，我做空了。

欢迎所有想法。

提前谢谢

Answer 1

到目前为止，我发现似乎m2eclipse正在使用.m2 / settings.xml中指定的代理，但是如果重新解析一个原型，它会忽略nonProxyHosts。

我向m2eclipse projekt提交了一份Bug报告： https://bugs.eclipse.org/bugs/show_bug.cgi?id=348893

请求帮助。

Answer 2

我们（我的团队，也就是）也遇到了这个问题。命令行Maven就像一个魅力，在Eclipse中我们得到了Maven的红色墙（我们通过Nexus代理所有依赖项）。

我注意到，一旦我在离线模式下设置m2eclipse，它就会找到所有依赖项。由于我经常在命令行中构建，因此以这种方式解析新的依赖关系对我来说不是问题（对某些人来说仍然可能很烦人）。

Answer 3

Eclipse - ＆gt;窗口 - ＆gt;偏好 - ＆gt; Maven

取消选中该选项 - 不要自动更新远程存储库中的依赖项。

这应该解决问题。

m2eclipse无法解决nexus的原型问题
