m2e Eclipse indigo出现错误

Question

我已经在没有eclipse的情况下在本地安装了Maven项目，它成功地完成了。现在我已经下载了Eclipse indgo 3.7.0。由于Eclipse-indigo使用了m2e(Maven2eclipse)插件，因此通过以下方式启用了它

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中添加项目作为maven项目，但我在运行pom.xml文件时遇到错误：

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插件的问题，我如何解决这个错误？

在将现有的maven项目导入到eclipse时，也会出现以下错误：

Answer 1

已解决问题，问题是因为在组织中工作(在组织中启用了代理)，并且在maven in 5 min not working提供的settings.xml中启用了代理

Answer 2

检查本地存储库下org/apache/maven/plugins/maven-resources-plugin/中的sha1校验和，如果有错误，请删除maven-resources-plugin目录。或者直接删除目录，让maven重新下载。

Answer 3

Eclipse有一个内置的Maven实现。尝试使用与Eclipse相同的Maven版本从命令行编译项目，或者在Eclipse中设置Maven安装(窗口/首选项/ Maven /安装)。
