maven - 如何在不使用“硬”依赖项的情况下在程序集中包含另一个模块的构建输出？

Question

我的（非常简化的）Maven 项目，包括所需的输出文件如下所示：

.
│   pom.xml
├───db-delivery
│   │   assembly.xml
│   │   db-delivery-info.txt
│   │   pom.xml
│   └───target
│           db-delivery-1.0.0-SNAPSHOT.zip
└───delivery
    │   assembly.xml
    │   delivery-info.txt
    │   pom.xml
    └───target
            delivery-1.0.0-SNAPSHOT.zip

的内容delivery-1.0.0-SNAPSHOT.zip看起来像这样（db-deliveryZIP 文件只包含db-delivery-info.txt）：

.
│   delivery-info.txt
└───db
        db-delivery-info.txt

如果我执行mvn verify一切都很好。但是由于 to 的依赖msa:delivery，msa:db-delivery:zip一些需要依赖解析的“快速” Maven 目标无法执行，例如mvn dependency:treeor mvn org.basepom.maven:duplicate-finder-maven-plugin:check。问题是，除非package涉及阶段，否则反应堆中的 ZIP 文件db-delivery不可用，这会导致Could not find artifact msa:db-delivery:zip:1.0.0-SNAPSHOT目标在delivery.

我试图将依赖类型从更改zip为pom. 这样，“快速”目标就起作用了，但是如果我mvn verify再次执行“完整”构建（db-delivery-1.0.0-SNAPSHOT.pom文件。

有没有办法在不直接依赖（类型）的情况下将 ZIP 工件db-delivery放入程序集中？只要我确保模块是在之前构建的（例如依赖于 type ），必要的文件在需要时就可用，所以从技术上讲这应该是可能的。deliveryzipdb-deliverydeliverypom
