从Gradle依赖项中排除.class文件

Question

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

意外的顶级异常:com.android.dex.DexException:多个dex文件定义Lorg/apache/commons/codec/binary/Base64;

Commons.codec是我的项目的依赖项,但不是直接的翻转项目,我认为它来自其中的一个罐子.如果我打开Kickflip的classes.jar,我可以看到.class文件.

如何排除从kickflip导入Base64.class到最终版本？我已经看过使用ziptree来排除东西,但却无法获得任何工作.

谢谢

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/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)
            }
        }
    }
}

    compile fileTree(dir: 'libs', include: '*.jar')

问题可能是 Base64 类包含了两次。它位于“google-http-client”中（查看它）。尝试排除此类。如果幸运的话，作为一个 Util 类，它不会在代码中使用。

在你的 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，但听起来有可能
