本文介绍了解决MyEclipse启动时遇到的无法更新中央仓库索引的问题。通过禁用启动时下载仓库索引更新，可以避免此错误。步骤包括启用Maven4MyEclipse特性并调整相关设置。

Unable to update index for central http://repo1.maven.org/maven2/ 就是这句，myeclipse启动后控制台输出这句话：
解决办法：
1.在myeclipse3.4（我用的这个版本）里面Window => Preferences => Myeclipse Enterprise Workbench => Maven4Myeclipse => Maven=>禁用Download repository index updates on startup
如果没有，则首先你要 Window => Preferences => Myeclipse Enterprise Workbench => Maven4Myeclipse 
这个里面启用 Enable Maven4Myeclipse features ，打上勾，要先启用这个插件 
这样 Window => Preferences => Myeclipse Enterprise Workbench => Maven4Myeclipse => Maven 
就有了！再选中就好了！ 
其实上面还有一项 offline 的！呵呵！我直接就把这个选上了！哈哈！

这个问题一般是因为 Maven 没有找到用户的 settings.xml 文件所致，可以按以下步骤解决： 1. 确认用户 home 目录下的 .m2 文件夹是否存在... <url>https://maven.aliyun.com/repository/central</url> </mirror> ```

新配置了一个maven的环境，远程仓库默认为maven官网的，然后发现在myeclipse里用maven搜索jar包时，一个都搜不到，于是开始找原因，试了各种办法，还是不行。 后来查了一下maven需要在update index之后才能帮助我们自动搜索jar包。 解决办法，手动update index： 1、首先手动去官网下载这两个文件， http://repo1.maven.org/ma
