Java 自动解析自定义jar的依赖关系层次结构

我正在与maven依赖性作斗争。maven依赖层次结构在我添加自定义构建jar的项目中没有得到解析。这有点令人困惑，因为其他外部提供的依赖项（如org.json、reasteasy jaxrs）的所有依赖项都很好地显示在dependency hierarchy视图中

项目结构：项目是一个平台，由使用相同项目支持模块的多个服务组成。此外，项目支持也将用于外部项目（此处为项目消费者）

• 项目父项目（pom）
  • 项目支持（jar）
  • 项目服务a（战争）
  • 项目服务b（jar）
• 项目消费者（war）
  • 项目支持（jar）

因此，在查看project serviceA依赖关系层次结构（以及有效的pom）时，不包括项目支持所需的依赖关系，这会导致代码编译错误。此外，项目支持用于项目父项目范围之外的项目

所以我的问题是：为什么maven不解析项目支持的依赖关系树并将它们添加到有效的pom中

提前谢谢

您已将依赖项的范围设置为在家长的依赖项管理部分中提供的范围。根据，依赖范围用于限制依赖的传递性

上面链接的介绍还包括一个表，声明哪些作用域在传递性游戏中起作用，哪些不起作用。提供的范围不是传递性的一部分

---

因此，解决方案是不在依赖项管理中声明任何范围，而是在依赖项使用中声明一个合理的范围。

感谢链接，在这样的背景下，我终于理解了这一点。这可能会影响我们的部署策略，但解决方案是可行的。谢谢
