我有一个示例/玩具 JNI 项目，我正在尝试使用 Maven 来管理和构建。子项目有：

  • MathFuncs : 纯本机代码 (C++)
  • JMathFuncsNative：在 JNI 中包装 MathFuncs 类的本机代码
  • JMathFuncs：加载 JMathFuncsNative 并调用其方法的 Java 存根代码
  • JHello：使用 JMathFuncs 的 Java 应用程序代码

每个项目应该只直接依赖于它上面的工件，并且应该对它上面的所有东西都有传递依赖。

当我mvn dependency:tree在每个项目上运行时：

  • MathFuncs 不依赖任何东西（正如预期的那样）。
  • JMathFuncsNative 依赖于 MathFuncs（如预期的那样）：运行时为 dll，编译时为 lib 和 inczip。
  • JMathFuncs 依赖于 JMathFuncsNative（运行时范围），但不获取传递的 MathFuncs 依赖项。
  • JHello 依赖于一切（如预期的那样）。

当我mvn dependency:tree从父目录运行时：

  • MathFuncs 不依赖任何东西（正如预期的那样）。
  • JMathFuncsNative 依赖于 MathFuncs（如预期的那样）：运行时为 dll，编译时为 lib 和 inczip。
  • JMathFuncs 依赖于 JMathFuncsNative（运行时范围），但不获取传递的 MathFuncs 依赖项。
  • JHello 依赖于 JMathFuncs（编译范围），它依赖于 JMathFuncsNative（运行时范围），但 MathFuncs 依赖项不存在。

谁能帮我解决这些依赖关系？

编辑：
这是 POM。我已经编辑了上面的项目名称以匹配下面的 POM 中显示的内容。
