Maven中相同依赖项的不同版本

问题描述

我有一个依赖于 Woodstox 和 XStream 的 maven 项目.不幸的是，XStream 也依赖于 Woodstox，但版本比我需要的稍旧.但与此同时，Woodstox 库的工件名称发生了变化，因此 maven 不会将它们视为同一工件的多个版本.但是包名和类名是一样的，就是运行时有冲突.

I have a maven project that depends on both Woodstox and XStream. Unfortunately XStream also depends on Woodstox, but a version slightly older than what I need. In the meantime though, the artifact names of the Woodstox libs changed, so maven won't consider them multiple versions of the same artifact. But the package and class names are the same, which means there is a conflict at runtime.

现在，我显然可以以某种方式从构建中破解旧的woodstox jar(在我们的例子中是 war 文件)，但是解决此类问题的正确方法是什么?

Now, I could obviously hack the old woodstox jar out of the build (a war file in our case) somehow but what is the proper way of solving this type of problem?

推荐答案

您可以在 xstream 的 dependency 声明中尝试 exclude woodstox 依赖.

You could try excluding woodstox dependency in your dependency declaration for xstream.

  <dependency>
        <groupId>xstream.group</groupId>
        <artifactId>xstream</artifactId>
        <version>a.b.c</version>
        <exclusions>
            <exclusion>
                <groupId>woodstox.group</groupId>
                <artifactId>woodstox</artifactId>
            </exclusion>
        </exclusions>
  </dependency>
