android - java.lang.NoClassDefFoundError : kotlin. jvm.internal.Intrinsics - newApplication

Question

问题

我只是想将自定义 AndroidJUnitRunner 类从 Java 转换为 Kotlin。

代码

CustomTestRunner.java

public class CustomTestRunner extends AndroidJUnitRunner {
    @Override
    public Application newApplication(ClassLoader cl, String className, Context context) throws IllegalAccessException,
        ClassNotFoundException, InstantiationException {
        return super.newApplication(cl, TestApp.class.getName(), context); 
    }
}

CustomTestRunner.kt -(导致错误 - 请参阅下面的堆栈跟踪)

class CustomTestRunner : AndroidJUnitRunner() {
    override fun newApplication(cl: ClassLoader, className: String, context: Context): Application {
        return super.newApplication(cl, TestApp::class.java.name, context)
    }
}

build.gradle

android {
  defaultConfig {
    testInstrumentationRunner "<>.CustomTestRunner"
  }
}

dependencies {
  compile "org.jetbrains.kotlin:kotlin-stdlib:1.2.0"
  androidTestCompile "org.jetbrains.kotlin:kotlin-stdlib:1.2.0"
}

错误

你可能缺少类路径依赖:

buildscript {
    . . . 
    dependencies {
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:1.3.20"
    }
}
