### 解决思路：   先将parent工程（最外面的哪个）pom 先clean   --> 然后再 install   还不行，重启一下idea，再clean - install ###

### 出错情况： ###

在对parent工程（最外面的哪个）pom 先clean，后install时，发现parent的pom依赖 子模块，install parent的时候出现 找不到 子模块；而子模块进行install时出现错误，无法执行；

###    原因：子模块与父工程 的dependency出现错误 ###

### 解决思路：重新检查各个模块的dependency是否出现错误，并修改 ###

### 例如： 我的项目的相关依赖关系为   服务者与消费者 都依赖于 api模块， ###

### 但出错的原因变成：服务者与消费者 都依赖于父工程，而父工程进行install时需先将子模块先进行install；所以出现死循环。 ###
