解决gradle中的重复依赖性反应本

Question

我正在尝试使用两个视频聊天库（Opentok和Skylink）的React-Native应用程序。两者都使用org.webrtc（libjingle），在构建过程中，我们有一个问题：

在opentok build.gradle中我们有：

apply plugin: 'com.android.library'
android {
    compileSdkVersion 23
    buildToolsVersion "23.0.2"
    defaultConfig {
        minSdkVersion 16
        targetSdkVersion 22
        versionCode 1
        versionName "1.0"
        ndk {
            abiFilters "armeabi-v7a", "x86"
        }
    }
}
dependencies {
    compile 'com.facebook.react:react-native:+'
    compile('com.opentok.android:opentok-android-sdk:2.10.+') {
        exclude group: 'org.webrtc'
    }
    compile project(':react-native-permission-helper')
}

和Skylink Build.gradle

apply plugin: 'com.android.library'
buildscript {
    repositories {
        jcenter()
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.2.2'
    }
}
android {
    compileSdkVersion 23
    buildToolsVersion "23.0.2"
    defaultConfig {
        minSdkVersion 16
        targetSdkVersion 22
        versionCode 1
        versionName "1.0"
        ndk {
            abiFilters "armeabi-v7a", "x86"
        }
    }
}
dependencies {
    compile fileTree(include: '*.jar', excludes: ['libjingle_peerconnection.jar', 'libjingle_peerconnection_java.jar'], dir: 'libs')
    compile(group: 'sg.com.temasys.skylink.sdk', name: 'skylink_sdk', version: '0.9.7-RELEASE', ext: 'aar')
    compile 'com.facebook.react:react-native:+'
    compile project(':react-native-permission-helper')
}

但是这种配置仍然不起作用。在最终构建步骤中，两个" libjingle_peerconnection.jar"仍在包括。我可以为此获得一些帮助吗？我们可以控制Gradle构建脚本，但不能控制第三方SDK。

我能够通过在我的主构建中添加以下任务来解决此问题（尽管以短速度的方式）。

tasks.create("excludeTask") << {
    File file = file("${buildDir}/intermediates/exploded-aar/com.opentok.android/opentok-android-sdk/2.10.1-REL-2756/jars/libs/libjingle_peerconnection_java.jar");
    println("Excluding file " + file)
    if (file.exists()) {
        file.delete();
    }
}
tasks.whenTaskAdded({
    if (it.name.matches(/^process.*Resources$/)) {
        it.dependsOn excludeTask
    }
})
