如何从Maven项目多模块和Spring Boot生成依赖项的jar文件

Question

我有

• 项目A（父级）
  • pom.xml
• 项目B
  • pom.xml
• 项目C
  • pom.xml
• 项目D
  • pom.xml包含（依赖项B和C）

当我构建项目D时，我没有B.jar和C.jar。我有2个名为B和C的文件夹。

我需要B.jar和C.jar。拜托，该怎么做？

the code above is the parent.

<!-- begin snippet: js hide: false console: true babel: false -->

此代码具有许多依赖性。但是，此项目的构建不会生成jar文件。
