maven-2 - 在Maven中隐式包括可选依赖项

Question

我有一个具有依赖项X的项目A。依赖项X有一个可选的依赖项Y，默认情况下不会包含在A中。有没有办法在我的POM中不包含Y的方法？在Ivy中，他们有一种方法可以确保包含X的所有可选依赖项，Maven是否有办法做到这一点？

Answer 1

根据Maven文档:

Optional dependencies - If project Y depends on project Z, the owner of project Y can mark project Z as an optional dependency, using the "optional" element. When project X depends on project Y, X will depend only on Y and not on Y's optional dependency Z. The owner of project X may then explicitly add a dependency on Z, at her option. (It may be helpful to think of optional dependencies as "excluded by default.")
