java - IllegalStateException：无法初始化插件：接口 org.mockito.plugins.MockMaker

Question

我正在尝试编写单元测试。我正在使用 Kotlin DSL。但是，我收到此错误：

"C:\Program Files\Java\jdk1.8.0_271\bin\java.exe" -ea -Didea.test.cyclic.buffer.size=1048576 "-javaagent:C:\Program Files\Android\Android Studio\lib\idea_rt.jar=52357:C:\Program Files\Android\Android Studio\bin" -Dfile.encoding=UTF-8 -classpath "C:\Program Files\Android\Android Studio\lib\idea_rt.jar" com.intellij.rt.execution.CommandLineWrapper C:\Users\Andris\AppData\Local\Temp\idea_classpath1129980195 com.intellij.rt.junit.JUnitStarter -ideVersion5 -junit4 com.commonsense.mobile.SplashViewModelTest
