idea日志一堆报错

搞了3天，终于今天解决了

原因：刚开始不知道maven 仓库和镜像什么作用，不知道的去搜索看，它们之间的关系把。

然后用idea 打开settings.xml 文件

因为idea 能检车setting.xml 文件是否格式错误，可以避免因为文件问题各种bug 无解。

好了，如果以上问题都没有，注意看一下你的磁盘空间是否满？ 因为满了的话。索引文件是不会成功的啊

如果以上问题没有

因为官方maven 中央仓库在国外，国内网速垃圾。各种限制，阿里云maven 又不支持索引文件下载。mamamiya

我目前只知道华为的maven 镜像 可以支持索引。于是我们在setting.xml 文件设置镜像。

以下是我的setting.xml 整个文件的信息，已经有华为maven镜像了的

maven 可以显示的啊

关键问题不在这里，我知道你们进来应该是关于 远程仓库 update 时候 

要么error 要么，索引文件下载好了 结果一点反应都没有，继续update 反复下载。

如果你不是，这边帖子也帮不了你

经过我发现，这里update 时候需要下载两个文件 

nexus-maven-repository-index.gz
nexus-maven-repository-index.properties

就是这两个文件，但是华为的镜像没有第二个文件，就离谱

所以解决方案：如果是error 那么应该是 setting.xml 文件设置有错误，idea 打开它，看看有没有红色，把红色解决掉的好了

如果是 update 后 下载所以文件了没反应 没有效果。

需要下载这个文件https://repo1.maven.org/maven2/.index/nexus-maven-repository-index.properties

 

然后把这个文件 复制到 idea 下载的索引文件的位置上去 

我不知道你电脑的索引文件在哪？

 

然后我们再去 maven 重新update  一下

我想如果还不行，清理垃圾 ，请重启电脑，重新进idea  去update  一下。

我想应该就好了

我就是这样的，虽然不知道为什么，我只知道我搞了3 天终于可以了

如果你还不行，我也没用办法，我也不知道

为什么我之前 一直update 后 索引文件有 却没用反应。现在我可能知道原因了

因为maven 需要两个文件

而华为maven 只下载了一个文件

另外一个文件我们需要自己去下载

还有，我电脑c盘空间不足。导致解压maven 索引文件，失败。
