如何在Maven中将同级模块作为我的Spring Boot测试的测试依赖项？

我有一个带有弹簧启动Web应用程序（ querying-api ），一个公共库（ domain-definitions ）和一个初始化程序的多模块maven项目。脚本（数据库加载器）。

我正在 querying-api 模块中编写测试用例以测试我的API，并且我想在测试开始之前运行 database-loader 服务使用预定义的测试数据加载数据库，同时测试加载程序是否仍在工作。但是，运行mvn clean package时出现以下错误：

[ERROR] Failed to execute goal on project querying-api: Could not resolve dependencies for project com.my.little.package:querying-api:jar:1.0.0: Failure to find com.my.little.package:database-loader:jar:1.0.0 in http://mycompanysnexusrepo.com/nexus/content/repositories/EAJAVA/ was cached in the local repository, resolution will not be reattempted until the update interval of EAJAVA has elapsed or updates are forced -> [Help 1]

测试没有问题，可以引用常见的 domain-definitions 库...

这可能是由于在本地存储库中找不到库jar。您需要先执行：
mvn clean install。这会将lib jar安装在本地存储库中，并且在执行 package 目标时，maven可以轻松找到它。

此处解释：How are "mvn clean package" and "mvn clean install" different?

此外，如果仅在测试中使用同级模块，则可以将范围定义为 test 依赖项。

     <dependency>
        <groupId>com.my.little.package</groupId>
        <artifactId>domain-definitions</artifactId>
        <scope>test</scope>
    </dependency>

如何在我的Maven Spring Boot多模块项目的测试中引用同级模块？
