聲明:我是Scala的新手,並試圖在IntelliJ IDEA中使用簡單的Scala archtype創建示例Scala Maven項目。 IntelliJ版本是14.1.2Scala模塊在IntelliJ Idea Maven項目中的Scala簽名錯誤
下面是我的pom文件,我沒有將2.7版本的Scala版本更改爲2.11.6,默認情況下該版本是由原型生成的。

在運行Maven的測試中,我不斷收到以下錯誤 -
[WARNING] error: error while loading JUnit4, Scala signature JUnit4 has wrong version
[WARNING] expected: 5.0
[WARNING] found: 4.1 in JUnit4.class
我不知道如何解決這個問題?
我無法複製此內容。這是一個非常奇怪的警告,特別是因爲沒有JUnit版本5.0。你有沒有嘗試[文件] - > [無效緩存/重新啓動...]?這爲我之前修復了一些奇怪的錯誤。儘管如此,這個XML仍然會產生一些警告,因爲各個依賴似乎取決於不同的Scala 2.11版本;所以你應該從這些依賴中排除Scala。 –
有沒有找到一個解決這個問題? – DJElbow
