问题描述
我想构建一个包含以下模块的多模块 SpringBoot 应用程序：
-
App：父模块，主类在这里
-
模型：所有领域对象，没有主类，没有测试
-
测试：专用于整个应用测试，将进行 Cucumber 测试
我的问题是：
我实际上可以在 Tests 模块中对 Model 的对象运行单元测试，但在 App 模块上执行 mvn clean install失败，因为 Tests 模块对 Model 的对象一无所知。
-
一方面，Spring 可以完成工作，导入所有需要的类 来自 Model 模块并对其运行测试。
-
另一方面，Maven 因以下错误而哭泣：
package com.my-app.model.my-package does not exist。
好的，Spring 和 Maven 是 2 个不同的工具，但是我应该在应用程序的 POM 中做什么来明确声明模型模块中的所有对象都应该导出到测试模块以进行测试？

测试'模块 POM 仅在 Model 模块上声明了一个 <dependency> 块。
测试模块和模型在各自的 POM 中都没有任何 <build> 块。
如here所示，一切都应该只由应用的 POM 管理。
所以我的问题是：我应该在 App 的 POM <build> 块中添加什么才能有效地将所有 Model 的包和类导出到 测试模块，以便mvn clean install整个项目？
提前致谢。
编辑：用于测试和模型模块的 POM.xml
