免责声明:我是 Scala 的新手,并尝试在 IntelliJ IDEA 中使用简单的 scala archtype 创建一个示例 Scala Maven 项目。IntelliJ 版本为 14.1.2
下面是我的 pom 文件,我确实将 Scala 版本从原型默认生成的 2.7 更改为 2.11.6。

在运行 Maven 测试时,我不断收到以下错误 -
[WARNING] error: error while loading JUnit4, Scala signature JUnit4 has wrong version
[WARNING] expected: 5.0
[WARNING] found: 4.1 in JUnit4.class
我不知道如何解决这个问题?
