eclipse(kepler):maven插件(m2e,1.4.0):

我刚刚下载并安装了“Eclipse IDE for Java EE Developers”,这是一个包解决方案 – 其他插件 – m2e插件.

在Eclipse中重建maven中央存储库的索引时,会收到以下错误:

“Unable to update index for central|http:
//repo.maven.apache.org/maven2:
[…]/.m2/repository/.cache/[…]/nexus-maven-repository-index.zip
(Datei oder Verzeichnis nicht gefunden)”

检查缓存,我找到一个文件“nexus-maven-repository-index.gz”,但没有zip文件.

我错过了maven插件的一些配置选项吗?
如果没有,怎么了?
(在central.maven.org/maven2/.index/只有一个gz文件,那么为什么m2e搜索一个zip文件?)

提前非常感谢您的帮助.

更多细节:

为了将潜在的Eclipse问题与Maven问题分开,您可以尝试安装最新版本的Maven并将其设置为Eclipse(Windows>首选项> Maven).
