使用Eclipse安装了maven插件之后,创建Maven工程,发现添加依赖“Add Dependency”的时候无法自动搜索远程库。

 

如果不能搜索远程库那用这个插件有啥用撒。。。

 

查遍了所有的maven配置文件都没发现问题。

 

最后发现是插件本身的问题。原因是远程库的索引没有成功的建立。

 

很有可能安装插件之后的某一次“Update Indexes”失败之后,导致默认的index“http://repo1.maven.org/maven2/”无法继续更新。所以每次都会报错: Unable to update index for central http ://repo1 .maven .org /maven2 / 。

 

也就说一次更新失败导致了以后的Update index都失败了。

 

这个时候执行以下操作:

 

http://readthefuckingmanual.net/error/2394/

 

Do in eclipse: window->show view->other->maven->maven indexes. One of the indexes is:
http://repo1.maven.org/maven2.
right-click on this one, and try rebuild index.
If that does not work, create a new index with the same address, and do a rebuild of that. With me that worked, and I could remove the original one. After this a restart of eclipse will NOT show the error anymore, and the add dependency search function operates as it should. Problem solved.

 

另外,参考 http://forum.springside.org.cn/redirect.php?tid=2876&goto=lastpost ,可以获得加快索引建立的方法。
