仅当我尝试发布或调试我的应用程序的 apk 时才会发生错误。我可以直接从 Android Studio 在我的设备上运行或调试它。来自 this问题,我知道这可能是由于重复的依赖关系。所以我尝试通过运行检查是否有任何重复的依赖项:
./gradlew -q :app:dependencies
我得到了以下依赖树:

如何从这棵树中推断出我的项目中哪些是重复的依赖项?他们是以星号结尾的吗?
编辑:我的 Gradle 文件如下所示
apply plugin: 'com.android.application'
android {
compileSdkVersion 25
buildToolsVersion "25.0.3"
defaultConfig {
applicationId "com.mycompany.myapp"
minSdkVersion 19
targetSdkVersion 25
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
exclude group: 'com.android.support', module: 'support-annotations'
})
compile 'com.android.support:appcompat-v7:25.3.1'
compile 'com.android.support:cardview-v7:25.3.1'
compile 'com.android.support:recyclerview-v7:25.3.1'
compile 'com.android.support:design:25.3.1'
compile 'pl.droidsonroids.gif:android-gif-drawable:1.2.7'
compile 'com.google.android.gms:play-services-ads:10.2.6'
compile 'com.google.android.gms:play-services-location:10.2.6'
compile 'com.google.firebase:firebase-core:10.2.6'
testCompile 'junit:junit:4.12'
}
apply plugin: 'com.google.gms.google-services'
编辑 2:完整的 gradle 错误:
Error:Execution failed for task ':app:transformClassesWithDexForDebug'.
com.android.build.api.transform.TransformException: com.android.ide.common.process.ProcessException: java.util.concurrent.ExecutionException: com.android.dex.DexException: Multiple dex files define Landroid/support/v7/util/ThreadUtil$MainThreadCallback;
编辑 3:由于 support/v7/util/ThreadUtil.java 属于 RecyclerView 模块,我尝试使用以下内容排除设计库下的 RecyclerView 模块:dependencies { compile fileTree(dir: 'libs', include: ['*.jar']) androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', { exclude group: 'com.android.support', module: 'support-annotations' }) compile 'com.android.support:appcompat-v7:25.3.1' compile 'com.android.support:cardview-v7:25.3.1' compile 'com.android.support:recyclerview-v7:25.3.1' compile ('com.android.support:design:25.3.1') { exclude module: 'recyclerview-v7' } compile 'pl.droidsonroids.gif:android-gif-drawable:1.2.7' compile 'com.google.android.gms:play-services-ads:10.2.6' compile 'com.google.android.gms:play-services-location:10.2.6' compile 'com.google.firebase:firebase-core:10.2.6' testCompile 'junit:junit:4.12' }
还是不行。
最佳答案
根据您的评论,显然问题是第三方 SDK 分发了 recyclerview-v7
的 JAR。 , 你在 libs/
,与您的 recyclerview-v7
冲突依赖。
使用纯 JAR 进行依赖有缺点。
一是您倾向于忘记它们,特别是如果您还使用来自工件存储库的依赖项。例如,我什至没有考虑到 libs/
中可能有 JAR。在 my comment .
另一个是 Gradle 无法为它们执行任何类型的依赖解析。 Gradle 依赖工件元数据(POM 文件)来确定需要哪些依赖项。对于 JAR 文件,Gradle 假定“您正在做正确的事情”,在这种情况下,您的广告网络的一个 JAR 不是“正确的事情”。
此外,JAR 是 JAR,而不是 AAR。在这种情况下,您广告网络的工程师是非常奇怪的人。 recyclerview-v7
在其 AAR 中有 RecyclerView
的资源需求(例如,自定义属性)。基本上,通过分发一个包含 RecyclerView
的 JAR代码,他们注定了任何使用他们的 SDK 的人:没有人可以使用他们的 RecyclerView
因为它不完整(并且可能已经过时),没有人可以使用官方RecyclerView
由于类(Class)冲突。
至少,我建议您向广告网络投诉,敦促他们改用人工制品和一组适当的依赖项。
