【IDEA】 导入maven项目报错 Could not transfer artifact com.XX.XX:XX(PKIX path building failed)

背景

虽然标题貌似跟证书PKIX有关，实则没有半毛钱关系。昨晚上整理电脑的文件夹，将项目文件夹移动了位置，今天上午开完公司站会就开始车祸现场，一直到下午一点才解决。┭┮﹏┭┮

问题

解决

原因：idea中缓存maven仓库信息，由于项目文件地址改变，但是maven仓库信息并没有随之替换掉。

步骤：

• 找到本地项目maven repository仓库，删除
• 重启ideal，setting->Invalidate Caches/ Restart…
• maven重新import，搞定

反思

出现今天这次“车祸”主要是由于没有认真查看idea log，碰到问题，首先要认真查看日志，通过日志可以让自己准确定位错误问题。给大家一个“血”的经验~
