Question

正如标题所述，我通过在JUnit 4测试中简单地调用构造函数而收到此错误。该测试位于我的应用程序的库模块内部。

在我的设置中，这足以引起问题：

import okhttp3.mockwebserver.MockWebServer
import org.junit.Test

class MyTest {

  @Test
  fun test() {
    MockWebServer()
  }
}

模块的

build.gradle文件包含依赖项： testImplementation("com.squareup.okhttp3:mockwebserver:4.0.1")

这是完整的堆栈跟踪：

奇怪的是，如果我在app模块中运行相同的测试，则在添加testImplementation依赖项后，它会成功完成。

如果我将MockWebServer()换成OkHttpClient.Builder()，我也会得到类似的堆栈跟踪：

java.lang.NoSuchFieldError: Companion

    at okhttp3.internal.Util.<clinit>(Util.kt:69)
    at okhttp3.internal.connection.RealConnectionPool.<clinit>(RealConnectionPool.kt:261)
    at okhttp3.ConnectionPool.<init>(ConnectionPool.kt:37)
    at okhttp3.ConnectionPool.<init>(ConnectionPool.kt:39)
    at okhttp3.OkHttpClient$Builder.<init>(OkHttpClient.kt:430)

我还尝试了更复杂的实例化方式（例如，通常在@Before方法中，等等）。所有这些都导致相同的结果。
