Question

我正在将mapbox-sdk的依赖项集成到我的gradle构建文件中，并遇到我的依赖项树中重复的错误。如何排除必要的依赖关系？

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
    implementation "org.jetbrains.kotlin:kotlin-reflect:$kotlin_version"
    implementation 'com.android.support:appcompat-v7:28.1.1'
    implementation 'com.android.support:recyclerview-v7:28.1.1'
    implementation 'androidx.constraintlayout:constraintlayout:2.0.0-alpha2'
    implementation 'com.android.support:support-v4:28.0.0'
    implementation 'androidx.legacy:legacy-support-v4:1.0.0'

    // android exinterface
    implementation 'com.android.support:exifinterface:28.0.0'
    // mapbox sdk
    implementation 'com.mapbox.mapboxsdk:mapbox-android-sdk:6.7.0'
    // navigation sdk will transitively bring maps-sdk
    implementation 'com.mapbox.mapboxsdk:mapbox-android-navigation-ui:0.24.0-beta.1'
    implementation 'com.android.support:support-v4:28.0.0'
    implementation 'com.google.android:support-v4:r7'
    // multidex enabling
    implementation 'com.android.support:multidex:1.0.3'

    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'

}

我有多个androidx.fragment：fragment：1.0.0（*）条目，这似乎是问题所在。

我得到的异常是DexArchiveMergerException，如下所示：

./gradlew build 

> Task :app:transformDexArchiveWithExternalLibsDexMergerForDebug FAILED

Answer 1

在gradle.properties中添加以下行

android.useAndroidX=true
android.enableJetifier=true

通常由于以下情况之一而发生此错误：


二进制依赖项包含一个库，您的应用程序还包含一个库   直接依赖。例如，您的应用声明了直接   对库A和库B的依赖，但是库A已经包括   库B的二进制文件。要解决此问题，请将库B删除为   直接依赖。

您的应用具有本地二进制依赖性和远程   对同一库的二进制依赖性。要解决此问题，请删除   二进制依赖项之一。
