在尝试使用Arquillian运行我的测试时，我得到了这个很好的例外：

我知道other questions并且ServerSetupObserver可能存在于我的类路径中的多个版本中。我的情况不同的是，如果我从一个蚂蚁目标运行我的测试，那么它们就完全没问题了，我从IntelliJ运行测试时只会遇到这个错误。
问题是：我如何确定IntelliJ在类路径上放置ServerSetupObserver类的确切位置和/或如何从那里删除它？ （或者这里还有什么问题？）
答案 0 :(得分：0)
不是真正的答案，但我的解决方法：
我需要从所有模块中删除所有依赖项，并再次添加所需的依赖项。对于这样大小的项目，这可能会更加麻烦，但幸运的是，该项目还有使用Eclipse的人，他们的类路径也没问题，所以我可以使用Eclipse Dependency Sync插件来恢复我的依赖关系它们。
