Android：WireMock：com.android.dex.DexIndexOverflowException：方法ID不在[0，0xffff]：65536

Gradle 3.3，WireMock 2.6.0。由Gradle構建我的Android項目。我寫了Espresso，Mockito的單元測試，並且一切正常。Android：WireMock：com.android.dex.DexIndexOverflowException：方法ID不在[0，0xffff]：65536

這裏我的build.gradle：

dependencies { 
    // for folder "androidTest" 
    androidTestCompile 'com.android.support.test.espresso:espresso-core:2.2.2' 
    androidTestCompile "org.mockito:mockito-android:2.7.21" 
    androidTestCompile "org.powermock:powermock-api-mockito:1.6.6" 
    androidTestCompile 'org.powermock:powermock-module-junit4:1.6.6' 

    // for folder "test" 
    testCompile 'junit:junit:4.12' 
    testCompile 'org.powermock:powermock-api-mockito:1.6.6' 
    testCompile 'org.powermock:powermock-module-junit4:1.6.6' 
    }

我的項目是成功構建和單元測試成功運行。好。現在我想添加WireMock單元測試。所以，我改變我的build.gradle（如顯示此博客：http://handstandsam.com/2016/01/30/running-wiremock-on-android/）：

dependencies { 
// for folder "androidTest" 
androidTestCompile 'com.android.support.test.espresso:espresso-core:2.2.2' 
androidTestCompile "org.mockito:mockito-android:2.7.21" 
androidTestCompile "org.powermock:powermock-api-mockito:1.6.6" 
androidTestCompile 'org.powermock:powermock-module-junit4:1.6.6' 

//WireMock 
androidTestCompile("com.github.tomakehurst:wiremock:2.6.0") { 
    //Using Android Version Instead 
    exclude group: 'org.apache.httpcomponents', module: 'httpclient' 

    //Version conflict with our app's slf4j version 
    exclude group: 'org.slf4j', module: 'slf4j-api' 

    //Was getting a classpath conflict for org.objectweb.asm.AnnotationVisitor which is a part of 'net.minidev:asm' 
    exclude group: 'org.ow2.asm', module: 'asm' 

    //Was getting this warning, so decided to ignore this version included by WireMock. 
    //Warning:Dependency org.json:json:20090211 is ignored as it may be conflicting with the internal version provided by Android. 
    //In case of problem, please repackage with jarjar to change the class packages 
    exclude group: 'org.json', module: 'json' 
} 

// for folder "test" 
testCompile 'junit:junit:4.12' 
testCompile 'org.powermock:powermock-api-mockito:1.6.6' 
testCompile 'org.powermock:powermock-module-junit4:1.6.6' 
}

當我運行我的應用程序一切正常。但是，當我嘗試啓動Android的我插樁的單元測試，我得到了一個錯誤：

:app:compileDevAndroidTestShaders 
:app:generateDevAndroidTestAssets 
:app:mergeDevAndroidTestAssets 
:app:transformClassesWithDexForDevAndroidTest FAILED 

FAILURE: Build failed with an exception. 

What went wrong:

當訪問以大於64K（敏捷方法計數限制）的索引方法的DexIndexOverFlowException發生。這意味着android項目中實際的方法計數（引用）數量大於64K，應用程序的最終.dex文件將被拆分爲多個dex文件。在這種情況下，你應該讓你的應用程序支持multidex，以下列方式：

1-添加multidex依賴性：

compile 'com.android.support:multidex:1.0.1'

2-以下配置添加到應用程序/的build.gradle：

android { 

     defaultConfig { 

      multidexEnabled true 
     } 
    }

3-創建自定義應用程序的類來擴展MultiDexApplication

public MyApplication extends MultiDexApplication

4-將此自定義類作爲應用程序的入口點，在AndroidManifest.xml：

<application 
    android:name=".MyApplication"
