【问题描述】：
我已经在本地不使用eclipse设置Maven项目，成功完成。 现在我已经下载了 Eclipse indgo 3.7.0。由于 Eclipse-indigo 有 m2e(maven 2 eclipse )plugin 通过
启用它Eclipse->帮助->安装新软件->使用（Indigo - http://download.eclipse.org/releases/indigo)->通用工具->m2e（检查）并安装。
在 Eclipse 中将项目添加为 maven 项目，但在运行 pom.xml 文件时出现错误：
Downloading: http://mirrors.ibiblio.org/pub/mirrors/maven2/org/apache/maven/plugins/maven-resources-plugin/2.4.3/maven-resources-plugin-2.4.3.pom

这是m2e插件问题，我该如何解决这个错误？
在将现有 maven 项目导入 Eclipse 时也出现以下错误：

【问题讨论】：
-
你的 settings.xml 文件是什么样子的？在我看来，您以某种方式更改了 settings.xml ......但您不应该导致 ibiblio 不是 Maven Central 我建议改用 repo1.maven.org/maven2。
-
你检查过在命令行上构建你的项目只是 mvn clean package 吗？
-
@khmarbaise，来自 cmd maven 工作正常。唯一的问题是 eclipse 插件 m2e。
-
如果您没有更改其他内容，为什么您的 maven 会从 ibiblio 而不是 Maven Central 下载？我建议清理你的本地存储库（如上所述）并在命令行上做其他时间......顺便说一句：你在命令行上使用的是哪个版本的 Maven？

转到 maven settings.xml 文件并启用代理。 stackoverflow.com/questions/5704010/maven-in-5-min-not-working
