原因总结：

问题历程：

我是先安装了common模块到本地Maven仓库，这个模块是直接在子模块上构建并安装的。

api模块引用了common模块，但是再次构建api子模块是发生此异常。

异常分析：

Maven需要先找到项目父模块，然后通过父模块找到子模块安装的信息。所以需要先在父模块进行一次install，让Maven仓库有此项目的父模块的信息，这样才能通过父模块找到子模块。

解决方法：

删除本地仓库已安装的数据，重新在父模块上执行install即可成功解决！之后再从子模块上构建也不会出现此类问题了。

成功安装示例：

注：为防止安装了未完善的子模块，可以在父模块先把对应子模块的信息注释掉。
