任务执行失败：app:transformClassesWithJarMergingForDebug

Question

我目前正在开发一个 android 应用程序，但每当我尝试加载某些 jar 文件时，我都会收到以下错误：

错误：任务执行失败 ':app:transformClassesWithJarMergingForDebug'。 com.android.build.api.transform.TransformException： java.util.zip.ZipException：重复条目： android/support/annotation/WorkerThread.class

这是我的 gradle 文件

apply plugin: 'com.android.application'

android {
compileSdkVersion 23
buildToolsVersion "23.0.2"

defaultConfig {
    applicationId "company.example.com.mobileapp"
    minSdkVersion 16
    targetSdkVersion 23
    versionCode 1
    versionName "1.0"
    multiDexEnabled true
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}
}

dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:23.1.0'
compile 'com.android.support:design:23.1.0'
compile files('libs/apache-httpcomponents-httpclient.jar')
compile files('libs/apache-httpcomponents-httpcore.jar')
//compile files('libs/java-json.jar')
//compile files('libs/android-support-v4.jar')
compile files('libs/commons-codec-1.10.jar')
compile files('libs/commons-io-2.4.jar')
compile files('libs/commons-lang3-3.4.jar')
}

Answer 1

你正在添加这一行

编译fileTree(dir: 'libs', include: ['*.jar'])

所以去掉多余的线

dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:23.1.0'
compile 'com.android.support:design:23.1.0'
}

或

删除这一行

编译fileTree(dir: 'libs', include: ['*.jar'])

dependencies {
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:23.1.0'
compile 'com.android.support:design:23.1.0'
compile files('libs/apache-httpcomponents-httpclient.jar')
compile files('libs/apache-httpcomponents-httpcore.jar')
//compile files('libs/java-json.jar')
//compile files('libs/android-support-v4.jar')
compile files('libs/commons-codec-1.10.jar')
compile files('libs/commons-io-2.4.jar')
compile files('libs/commons-lang3-3.4.jar')
}

尝试清理您的项目。

Build -> Clean Project

清洁后再次运行。
