这个问题有很多原因，我遇到的一个场景如下，先给解决办法，再分析
解决办法：
仔细检查会发现，会发现有这个一个错误提示：
Multiple markers at this line
- The type org.apache.commons.pool2.impl.GenericObjectPoolConfig cannot be resolved. It is indirectly referenced from
required .class files
这个提示是包冲突，看到这个会想到maven依赖有冲突，注释掉多余的依赖问题则解决了（springboot 有个数据访问的项目 集成了commons.pool，我的是是pom中多加了一个commons.pool 的依赖）。

自己仔细找找看吧。
你应该在给些有用的错误信息才能判断的。
把项目重新build了一下，还是不行

这不写着吗？文件找不到，你看看这些class文件有没有，然后为什么没有，是不是没有编译，或者本来就错了。
