Question

我正在开发一个部署在WebSphere Liberty上的基本servlet。这个servlet使用我编写的自定义类来执行其业务逻辑。

我尝试为这个自定义类编写一些单元测试，我可以使用maven运行。但是当我启动maven test时，一些测试失败，出现以下异常：

我打算测试的类使用IBM Library JSON4J。当我的servlet部署在Liberty运行时内部时，该类可以毫无问题地运行，但显然在运行测试时maven找不到JSON4J。

请问您能解释我应该配置什么，以便在运行测试时不会抛出ClassNotFound？

我还附上了我的pom.xml，以防它可能有所帮助：
