Question

当我将浓缩咖啡导入gradle文件并尝试运行我的应用程序时，我得到了这个异常。

 Error:Execution failed for task   
 ':app:transformClassesWithJarMergingForDebugAndroidTest'.
 > com.android.build.api.transform.TransformException:     
 java.util.zip.ZipException: duplicate entry:     
 junit/extensions/ActiveTestSuite$1.class

我做了很多搜索，但仍然有这个问题。这是我的gradle文件。

apply plugin: 'com.android.application'
android {
  compileSdkVersion 24
  buildToolsVersion "24.0.0"
defaultConfig {
    applicationId "theo.testing.androidespresso"
    minSdkVersion 18
    targetSdkVersion 24
    versionCode 1
    versionName "1.0"
    multiDexEnabled true
    testInstrumentationRunner 'android.support.test.runner.AndroidJUnitRunner'
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
  }
 }
 dependencies {
  compile fileTree(dir: 'libs', include: ['*.jar'])
  testCompile 'junit:junit:4.12'
  androidTestCompile 'com.android.support:support-annotations:24.2.0'
compile 'com.android.support:appcompat-v7:24.2.0'
androidTestCompile('com.android.support.test.espresso:espresso-contrib:2.2.1') {
    // Necessary to avoid version conflicts
    exclude group: 'com.android.support', module: 'appcompat'
    exclude group: 'com.android.support', module: 'support-v4'
    exclude group: 'com.android.support', module: 'support-annotations'
}
  androidTestCompile 'com.android.support.test:testing-support-lib:0.1'
}

任何想法?

谢谢。

将您的build.gradle依赖项更改为:

dependencies {
  compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:24.2.0'
  testCompile 'junit:junit:4.12'
androidTestCompile 'com.android.support.test:runner:0.5'
androidTestCompile 'com.android.support:support-annotations:24.2.0'
androidTestCompile 'com.android.support.test.espresso:espresso-core:2.2.2'
androidTestCompile('com.android.support.test.espresso:espresso-contrib:2.2.1') {
    // Necessary to avoid version conflicts
    exclude group: 'com.android.support', module: 'appcompat'
    exclude group: 'com.android.support', module: 'support-v4'
    exclude group: 'com.android.support', module: 'support-annotations'
}
}
