java.lang.NoSuchFieldError：没有类型为Lorg / apache / http / conn / ssl / AllowAllHostnameVerifier的静态字段INSTANCE

Question

Android Studio 3.3

我想在 Espresso 测试中使用 WireMock 。

build.gradle：

buildscript {
    ext.KOTLIN_VERSION = '1.3.21'
    ext.ESPRESSO_VERSION = '3.2.0-alpha02'

    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.3.2'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$KOTLIN_VERSION"

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

app / build.gradle：

  buildscript {
    repositories {
        maven { url 'https://maven.fabric.io/public' }
    }

    dependencies {
        classpath 'io.fabric.tools:gradle:1.27.0'
    }
}
apply plugin: 'com.android.application'
apply plugin: 'kotlin-android-extensions'
apply plugin: 'kotlin-android'
// Need to autocreate tasks crashlyticsUploadDistributionXXX
apply plugin: 'io.fabric'

repositories {
    maven { url 'https://maven.fabric.io/public' }
    mavenCentral()
}

def keystoreProperties = new Properties()
keystoreProperties.load(new FileInputStream(rootProject.file("app/keystore.properties")))

android {
    dataBinding {
        enabled = true
    }

    compileSdkVersion 28
    defaultConfig {
        applicationId "com.myproject.android"
        minSdkVersion 18
        targetSdkVersion 28
        versionCode 6
        versionName "0.0.8"

        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"

        multiDexEnabled true
    }

    packagingOptions {
        exclude 'META-INF/DEPENDENCIES'
        exclude 'META-INF/LICENSE'
        exclude 'META-INF/LICENSE.txt'
        exclude 'META-INF/license.txt'
        exclude 'META-INF/NOTICE'
        exclude 'META-INF/NOTICE.txt'
        exclude 'META-INF/notice.txt'
        exclude 'META-INF/ASL2.0'
    }

    sourceSets {
        main.java.srcDirs += 'src/main/kotlin'
        androidTest.java.srcDirs += 'src/androidTest/kotlin'
        //androidTest.assets.srcDirs += 'src/androidTest/assets'
    }

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation('com.crashlytics.sdk.android:crashlytics:2.7.0@aar') { transitive = true; }

    implementation 'androidx.appcompat:appcompat:1.1.0-alpha03'

    implementation 'com.yuyh.json:jsonviewer:1.0.6'

    implementation project(':common')

    androidTestImplementation "androidx.test.espresso:espresso-intents:$ESPRESSO_VERSION"
    androidTestImplementation "androidx.test.espresso:espresso-contrib:$ESPRESSO_VERSION"

    androidTestImplementation 'androidx.test:rules:1.1.2-alpha02'
    androidTestImplementation 'androidx.test:runner:1.1.2-alpha02'

    androidTestImplementation("com.github.tomakehurst:wiremock:2.18.0")

    testImplementation 'junit:junit:4.12'
}

这里是意式浓缩咖啡的测试：

import androidx.test.runner.AndroidJUnit4
import org.junit.Rule
import org.junit.Test
import org.junit.runner.RunWith
import androidx.test.espresso.Espresso.onView
import androidx.test.espresso.matcher.ViewMatchers.*
import androidx.test.espresso.assertion.ViewAssertions.matches
import androidx.test.espresso.intent.rule.IntentsTestRule
import androidx.test.espresso.Espresso
import androidx.test.espresso.action.ViewActions.*
import androidx.test.platform.app.InstrumentationRegistry
import com.github.tomakehurst.wiremock.core.WireMockConfiguration.wireMockConfig
import com.github.tomakehurst.wiremock.junit.WireMockRule

@RunWith(AndroidJUnit4::class)
class AddTraderActivityTest {
    val context = InstrumentationRegistry.getInstrumentation().getContext()
    val targetContext = InstrumentationRegistry.getInstrumentation().getTargetContext()

    @get:Rule
    var addTraderIntentTestRule: IntentsTestRule<AddTraderActivity> = IntentsTestRule(AddTraderActivity::class.java)

    @get:Rule
    var wireMockRule = WireMockRule(wireMockConfig().port(8081))

 @Test
 fun toolbar_title() {
    onView(withId(R.id.toolbaTitleTextView))
            .check(matches(withText(R.string.traders)))
  }

但是在这一行中我得到了错误：

var wireMockRule = WireMockRule(wireMockConfig().port(8081))

我意识到这比您的问题来得晚，但是我想发布遇到相同问题时发现的内容，以防其他人遇到。

为了避免出现此特定问题，我不得不将Gradle中的依赖项引用更改为Wiremock的独立变体

来自：

androidTestImplementation("com.github.tomakehurst:wiremock:2.18.0")

收件人：

androidTestImplementation("com.github.tomakehurst:wiremock-standalone:2.18.0")

出于一致性考虑，我保留了原始海报的2.18.0版本，但是我使用2.26.0版本遇到了此问题。

我不确定为什么独立版本的依赖关系可以解决问题，但我怀疑它与另一个依赖关系有关，从而导致了某种潜在的冲突。
