我有这个 Maven 依赖项......
<dependency>
<groupId>javanettasks</groupId>
<artifactId>httpunit</artifactId>
<version>1.7</version>
<scope>test</scope>
</dependency>
我需要这个来进行一些我正在运行的测试。该库依赖于 xercesImpl v 2.4。问题是，当我们通过 Bamboo 集成服务器运行它时，我们会收到 ClassCastException，因为我们的服务器使用更高版本的 xerces。有谁知道我该如何调和这个？换句话说，有没有办法让我的 xercesImpl 在测试阶段在类加载器中优先？
