问题描述：

某些maven仓库的地址返回404,但是上级目录却存在，如以下的错误信息(从gradle报出):

FAILURE: Build failed with an exception.

* What went wrong:

A problem occurred configuring root project 'backend'.

BUILD FAILED

这些地址都会返回404,但是打开上一级目录（如：https://repo.huaweicloud.com/repository/maven/org/grails/plugins/database-migration/3.0.3/ ）却是可以列出目录下文件的，但是点击任意一个文件都会404

建议方案：

检查404的原因并修复
