我有一个应用程序需要几个不同版本的相同库。通过 intellij 运行时，这不是问题，因为它以一种避免冲突的方式导出类路径。然后我在编译生产时使用 maven shade 插件创建一个 uber-jar。

但是，当使用 surefire 插件运行我的单元测试时，冲突再次出现。有谁知道我可以确保万无一失的插件以避免这些冲突的方式创建类路径的方法？

谢谢！

更新：下面是我得到的错误（虽然它是相当特定于我的应用程序）。基本上有两个版本的 Saxon HE 和 PE 都在加载。运行 surefire 测试时，会导致此异常：

也许您也可以覆盖对测试范围的其他依赖？或者，如果需要，只需在默认范围内覆盖它们。或者有什么原因你不能做上述任何一个？

当然，另一种选择是在测试运行期间开始涉足类加载器，如下所示。
