Android 项目错误任务 ':transformClassesWithJarMergingForDebug' 执行失败

我正在将我的 Android 应用程序从 Eclipse 转换为 Android Studio。当我构建 gradle 时没有错误。但在运行应用程序时，我遇到了以下错误：

Error:Execution failed for task ':transformClassesWithJarMergingForDebug'.
> com.android.build.api.transform.TransformException: java.util.zip.ZipException: duplicate entry: org/xmlpull/v1/XmlPullParserException.class

我多次尝试清理/重建项目，但总是遇到相同的错误。 我还尝试了终端命令 ./gradlew 来清理它，但它不起作用。

Android Studio版本：2.1 摇篮版本：2.1.2 jdk版本：1.8 Android SDK 构建工具：24

构建.gradle代码：

    apply plugin: 'com.android.application'

dependencies {

    compile ('com.google.android.gms:play-services:9.0.2')
    compile 'com.android.support:appcompat-v7:24.0.0'
    compile files('libs/appcompat_v7.jar')
    compile files('libs/ksoap2-android-assembly-2.5.8-jar-with-dependencies.jar')
    compile files('libs/gcm.jar')
    compile files('libs/android.jar')
    compile files('libs/activation.jar')
    compile files('libs/additionnal.jar')

    compile ('com.google.android.gms:play-services-analytics:9.0.2')
    compile files('libs/libGoogleAnalyticsServices.jar')
    compile files('libs/mail.jar')
    compile "com.android.support:support-v4:24.0.0"
    compile "com.android.support:design:24.0.0"
    compile 'com.android.support:multidex:1.0.1'
}

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.1.2'
    }
}

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.3"
    useLibrary  'org.apache.http.legacy'

    defaultConfig {

        applicationId "com.expedite.apps.vedant"
        minSdkVersion 9
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
        multiDexEnabled true
    }


    sourceSets {
        main {
            manifest.srcFile 'AndroidManifest.xml'
            java.srcDirs = ['src']
            resources.srcDirs = ['src']
            aidl.srcDirs = ['src']
            renderscript.srcDirs = ['src']
            res.srcDirs = ['res']
            assets.srcDirs = ['assets']
        }

        // Move the tests to tests/java, tests/res, etc...
        instrumentTest.setRoot('tests')

        // Move the build types to build-types/<type>
        // For instance, build-types/debug/java, build-types/debug/AndroidManifest.xml, ...
        // This moves them out of them default location under src/<type>/... which would
        // conflict with src/ being used by the main source set.
        // Adding new build types or product flavors should be accompanied
        // by a similar customization.
        debug.setRoot('build-types/debug')
        release.setRoot('build-types/release')
    }
}

我解决了我的错误：

按照我的 build.gradle 代码：

    apply plugin: 'com.android.application'

dependencies {
    compile 'com.android.support:appcompat-v7:24.0.0'
    compile('com.google.android.gms:play-services:9.0.2')
    compile ('com.google.android.gms:play-services-analytics:9.0.2')
    compile files('libs/ksoap2-android-assembly-2.5.8-jar-with-dependencies.jar')
    compile "com.android.support:design:24.0.0"
    compile 'com.android.support:multidex:1.0.1'
    compile files('libs/mail.jar')
    compile files('libs/activation.jar')
    compile files('libs/gcm.jar')
}

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.1.2'
    }
}

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.3"
    useLibrary  'org.apache.http.legacy'

    defaultConfig {

        applicationId "com.expedite.apps.vedant"
        minSdkVersion 9
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
        multiDexEnabled true
    }
    packagingOptions {
        exclude 'META-INF/NOTICE.txt' // will not include NOTICE file
        exclude 'META-INF/LICENSE.txt' // will not include LICENSE file
        exclude 'META-INF/LICENSE-FIREBASE.txt'
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    dexOptions {
        javaMaxHeapSize "4g"
    }

    sourceSets {
        main {
            manifest.srcFile 'AndroidManifest.xml'
            java.srcDirs = ['src']
            resources.srcDirs = ['src']
            aidl.srcDirs = ['src']
            renderscript.srcDirs = ['src']
            res.srcDirs = ['res']
            assets.srcDirs = ['assets']
        }

        // Move the tests to tests/java, tests/res, etc...
        instrumentTest.setRoot('tests')

        // Move the build types to build-types/<type>
        // For instance, build-types/debug/java, build-types/debug/AndroidManifest.xml, ...
        // This moves them out of them default location under src/<type>/... which would
        // conflict with src/ being used by the main source set.
        // Adding new build types or product flavors should be accompanied
        // by a similar customization.
        debug.setRoot('build-types/debug')
        release.setRoot('build-types/release')
    }
}

在 AndroidManifest.xml 中添加这一行 android:name="android.support.multidex.MultiDexApplication"

<application
 .....
 android:name="android.support.multidex.MultiDexApplication">
</application>
