Question

我正在尝试使用gradle将https://github.com/Kickflip/kickflip-android-sdk导入到我的android构建中，我得到了：

意外的顶级例外情况： com.android.dex.DexException：多个dex文件定义Lorg / apache / commons / codec / binary / Base64;

Commons.codec是我项目的依赖项，但不是直接翻转项目，我认为它来自其中一个罐子。如果我打开Kickflip的classes.jar，我可以看到.class文件。

如何将Base64.class从kickflip导入到最终版本中？我已经看过使用ziptree来排除东西但却无法正常工作。

由于

我的build.gradle是：

apply plugin: 'android'

android {
    compileSdkVersion 19
    buildToolsVersion "19.0.3"

    defaultConfig {
        minSdkVersion 10
        targetSdkVersion 19
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            runProguard false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
        }
    }

    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_7
        targetCompatibility JavaVersion.VERSION_1_7
    }

    packagingOptions {
        exclude 'META-INF/DEPENDENCIES.txt'
        exclude 'META-INF/LICENSE.txt'
        exclude 'META-INF/NOTICE.txt'
        exclude 'META-INF/NOTICE'
        exclude 'META-INF/LICENSE'
        exclude 'META-INF/DEPENDENCIES'

        exclude 'META-INF/dependencies.txt'
        exclude 'META-INF/LGPL2.1'
        exclude 'META-INF/ASL2.0'
    }

    android.applicationVariants.all{ variant ->
        // This is an annoying hack to get around the fact that the Gradle plugin does not support
        // having libraries with different minSdkVersions. Play Services has a min version of 9 (Gingerbread)
        // but Android Maps Utils supports 8 (Froyo) still
        variant.processManifest.doFirst {
        File manifestFile = file("${buildDir}/exploded-aar/io.kickflip/sdk/0.9.9/AndroidManifest.xml")
            if (manifestFile.exists()) {
                println("Replacing minSdkVersion in Android Maps Utils")
                String content = manifestFile.getText('UTF-8')
                content = content.replaceAll(/minSdkVersion="18"/, 'minSdkVersion=\"10\"')
                manifestFile.write(content, 'UTF-8')
                println(content)
            }
        }
    }
}

dependencies {
    compile 'com.android.support:support-v4:19.1.0'
    compile 'io.kickflip:sdk:0.9.9'
    compile fileTree(dir: 'libs', include: '*.jar')
    compile project(':libs:typeface-textview:library')
    compile project(':libs:gpuimage')
    compile 'com.google.android.gms:play-services:4.3.23'

问题可能是Base64类包含两次。它位于'google-http-client'（view it）中。尝试排除此类。如果你很幸运，作为一个Util类，它不会在代码中使用。

在build.gradle中试试这个：

package com.google.api.client.util;

 sourceSets {
     main {
         java {
             exclude 'com.google.api.client.util.Base64.java'
             exclude 'org.apache.commons.codec.binary.Base64.java'
         }
     }
}

注意：我还没有尝试过，但听起来像是一种可能性

从Gradle依赖项中排除.class文件
