android - 任务 ':app:dexDebug' 执行失败。不确定可能是 httpclient 和 httpmime 之间的依赖性问题

Question

在 Android Studio 中，我收到以下错误:-任务 ':app:dexDebug' 执行失败。

:app:compileDebugJava UP-TO-DATE :app:preDexDebug :app:dexDebug UNEXPECTED TOP-LEVEL EXCEPTION: com.android.dex.DexException: Multiple dex files define Landroid/support/annotation/AnimRes; at com.android.dx.merge.DexMerger.readSortableTypes(DexMerger.java:596) at com.android.dx.merge.DexMerger.getSortedTypes(DexMerger.java:554) at com.android.dx.merge.DexMerger.mergeClassDefs(DexMerger.java:535) at com.android.dx.merge.DexMerger.mergeDexes(DexMerger.java:171) at com.android.dx.merge.DexMerger.merge(DexMerger.java:189) at com.android.dx.command.dexer.Main.mergeLibraryDexBuffers(Main.java:454) at com.android.dx.command.dexer.Main.runMonoDex(Main.java:303) at com.android.dx.command.dexer.Main.run(Main.java:246) at com.android.dx.command.dexer.Main.main(Main.java:215) at com.android.dx.command.Main.main(Main.java:106)

• 尝试:使用 --stacktrace 选项运行以获取堆栈跟踪。使用 --info 或 --debug 选项运行以获得更多日志输出。

构建失败

我的 build.gradle 文件:-

apply plugin: 'com.android.application'

android {
    compileSdkVersion 21
    buildToolsVersion "21.1.2"

    defaultConfig {
        applicationId "info.androidhive.camerafileupload"
        minSdkVersion 15
        targetSdkVersion 21
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}



    dependencies {
        compile fileTree(dir: 'libs', include: ['*.jar'])
        compile 'com.android.support:appcompat-v7:21.0.3'
    //compile files('libs/httpclient-4.3.6.jar')
    //compile files('libs/android-support-v4.jar')
    //compile files('libs/httpcore-4.3.3.jar')
    //compile files('libs/httpmime-4.3.6.jar')
    //compile "org.apache.httpcomponents:httpmime:4.3.6"

    }

任何人都可以建议我如何解决它......？

Answer 1

你的build.gradle包含compile 'com.android.support:appcompat-v7:21.0.3'这个库依赖在 v4 支持库上。所以它会被gradle添加。你也有 android-support-v4.jar 在你的 libs 文件夹和行 compile fileTree(dir: 'libs', include: ['*.jar' ])，因为 AS 将尝试使用同一库的 2 个实例来构建它。

解决方案是从 libs 文件夹中删除 android-support-v4.jar 并重建项目。

更新:

添加到build.gradle下一个 block

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