今天导入一个Maven项目，里面有多个Maven子模块。完成后发现子模块并没有被识别，代码都是灰色的。原因可能是因为我导入外部的项目时，只加载了父Maven，而内部的子Maven没有被搜索到。

打开tool windows下的Maven果然只看见了父maven。

解决方法：

**方法一：**

1、打开“View → Tool Windows → Maven”出现如下界面

2、点击加号，选择子模块下的 `pom.xml` 文件，然后点击 OK 即可

**方法二：**

重新导入子Maven

1、File → Project Structure → 点击“Modules” → 点击“+” → “Import Model”

2、选择子模块下的 `pom.xml` 文件导入即可
