当我运行 ./gradlew assembleDebug 时，我得到:

:app:dexDebug FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:dexDebug'.
> com.android.ide.common.internal.LoggedErrorException: Failed to run command:
    /home/grub/Main/android-sdk-linux/build-tools/19.1.0/dx --dex --num-threads=4 --output 

合并类和 jar 列表:

UNEXPECTED TOP-LEVEL EXCEPTION:
        com.android.dex.DexException: Multiple dex files define Landroid/support/v4/accessibilityservice/AccessibilityServiceInfoCompat$AccessibilityServiceInfoVersionImpl;

它与this 非常相似问题和问题应该在多个 support-v4 库中。我清理了 build.gradle :

repositories {
    maven { url "http://dl.bintray.com/populov/maven" }
    mavenCentral()
}

apply plugin: 'android'

android {
    compileSdkVersion 19
    buildToolsVersion '19.1.0'

    defaultConfig {
        minSdkVersion 9
        targetSdkVersion 19
        versionCode 8
        versionName "2.1.17"
    }
    dependencies {
        compile fileTree(dir: 'libs', include: ['*.jar'])
        compile 'com.android.support:support-v4:20.+'
        compile ('com.google.android.gms:play-services:5+'){
            exclude group: 'com.android.support', module: 'support-v4'
        }
        compile(project(':libraries:com.typefacedwidgets')) {
            exclude group: 'com.android.support', module: 'support-v4'
        }
        compile(project(':libraries:com.truepagerindicator')) {
            exclude group: 'com.android.support', module: 'support-v4'
        }
        compile ('com.sothree.slidinguppanel:library:+'){
            exclude group: 'com.android.support', module: 'support-v4'
        }
        compile ('com.github.chrisbanes.pulltorefresh:sample:2.1.1+'){
            exclude group: 'com.google.android', module: 'support-v4'
        }
        compile 'com.thoughtworks.xstream:xstream:1.4.7'
        compile 'com.squareup.retrofit:retrofit:1.6.1'
        compile 'com.squareup.okhttp:okhttp-urlconnection:2.0.0'
        compile 'com.squareup.okhttp:okhttp:2.0.0'
        compile 'com.google.code.gson:gson:2.3'
        compile 'de.greenrobot:eventbus:2.2.1'
    }
}

为了检查依赖关系，我做了 ./gradlew -q -dependencies 显示:

+--- com.android.support:support-v4:20.+ -> 20.0.0
|    \--- com.android.support:support-annotations:20.0.0

看起来应该没问题，但问题仍然存在。

更新:

问题出在 apkLib 依赖和来自 Gradle 的混淆消息中。它像在this中一样被解决了回答将 Android-PullToRefresh 放入 Gradle 中单独的 android 库项目中。

最佳答案

当我导入一些需要 Google Play 服务的库时出现这个错误，

我刚从:

compile 'com.google.android.gms:play-services:6.5.87'

到:

compile ('com.google.android.gms:play-services:6.5.87') {
    exclude module: 'support-v4'
}

现在它构建正常
