android - Prograurd 重复的 zip 条目

Question

我在签署和发布 APK 时遇到问题。我收到重复的 zip 条目警告和一个错误，这是代码:

Information:Gradle tasks [:app:assembleRelease]

我什至尝试向 gradle 添加打包选项，但它不起作用这是我的 gradle 代码:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 25
    buildToolsVersion "25.0.2"
    useLibrary  'org.apache.http.legacy'
    defaultConfig {
        applicationId "com.company.myapp"
        minSdkVersion 14
        targetSdkVersion 21
        versionCode 70
        versionName "7.4"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
        multiDexEnabled true
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    packagingOptions {
        exclude 'META-INF/MANIFEST.MF'
        exclude 'META-INF/NOTICE.txt'
    }
    lintOptions {
        checkReleaseBuilds false
        // Or, if you prefer, you can continue to check for errors in release builds,
        // but continue the build even when errors are found:
        abortOnError false
    }
}

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    //    compile 'com.android.support:appcompat-v4:25'
    testCompile 'junit:junit:4.12'
    //    compile fileTree(include: '*.jar', dir: 'libs')
    compile 'com.google.android.gms:play-services:10.2.1'
    //    compile "com.google.android.gms:play-services-gcm:10.2.1"
    //    compile 'org.apache.httpcomponents:httpmime:4.5.3'
    //    compile files('libs/gson-2.2.4.jar')
    //    compile files('libs/httpmime-4.2.2.jar')
    //    compile files('libs/joda-time-2.1.jar')
    //    compile files('libs/universal-image-loader-1.9.4.jar')
//    compile files('libs/android-support-v4.jar')

}

我在这个项目上呆了几天，我不知道该怎么办，欢迎任何帮助。

除了 Jared 的回答之外，如果您收到有关重复 .class 文件的错误，而不仅仅是 META-INF/ 文件，您可能需要排除包含重复的 .class 文件的有问题的模块。

您需要确定哪个依赖项包含具有重复 .class 条目的模块，并从所述依赖项中排除该模块。

您可以使用 Gradle 命令:./gradlew app:dependencies 列出完整的依赖关系图。其中“app:”是您项目的模块/应用程序的名称。

使用 ./gradlew app:dependencies 命令后，您应该查看依赖项列表并找到包含具有重复 .class 的违规模块的那个条目。

例如，假设 com.android.support:support-v4 是包含导致这些错误的重复类的模块。以下是如何从您的依赖项中排除该重复模块:

//Your dependency that includes the module with the duplicates.
compile('com.my.project:my-module:0.1') {
        //exclude the offending module so there won’t be duplicates.
        exclude module: 'support-v4'
        //maybe you need to exclude a group also?...
        exclude group: 'com.google.android.gms'
    }
