【Maven打包报错误】找不到或无法加载主类以及Could not resolve dependencies,Failed to collect dependencies的解决办法

核心：file=>invalidate caches + 重新clean和install一下parent(maven父模块)模块

最开始碰到的问题是更新了代码但是Swagger中找不到Controller服务，http调用也not found。其实这时候运行的是缓存，然后clean了报找不到主类

正常来说是存在这个Application类的：

1. 找不到主类先检查配置是否正确

2. 重新Maven clean 和 install

进入相应模块目录下面执行：mvn clean install -e

提示信息如下：

3.观察报错信息可知Failed to collect dependencies at com.zeroone.star:crm-common:jar:1.0.0-SNAPSHOT:重新打包一下common

还是报错提示fastdfs-spring-boot-starter有问题

4.重新clean和install一下parent

如果还是不行清掉IDEA缓存重新打开再进行以上步骤

PS：碰到Controller都删除了却还能运行服务的情况估计就是缓存作祟，以上办法已解决
