Maven-具有不同版本的可传递依赖项 [英] Maven - transitive dependencies with different versions

问题描述

• 假设我的应用程序需要foo.jar和bar.jar
• foo.jar需要c.jar的1.0版
• bar.jar需要c.jar的2.0版

• Let's assume my application needs foo.jar and bar.jar
• foo.jar needs version 1.0 of c.jar
• bar.jar needs version 2.0 of c.jar

Maven如何解决此冲突?将使用哪个版本的c.jar?

How does Maven resolve this conflict? Which version of c.jar will be used?

推荐答案

这取决于有效POM中声明的顺序.如果首先显示foo.jar，您将获得c.jar的1.0版.另一方面，如果首先声明bar.jar，则它将是c.jar的2.0版.

It depends on the order of declaration in your effective POM. If foo.jar shows up first you will get version 1.0 of c.jar. If on the other hand bar.jar is declared first it will be version 2.0 of c.jar.
