当我在implementation 'com.google.firebase:firebase-inappmessaging-display:17.2.0'中使用app/build.gradle时，出现此错误:
Duplicate class com.google.common.util.concurrent.ListenableFuture found in modules guava-20.0.jar (com.google.guava:guava:20.0) and listenablefuture-1.0.jar (com.google.guava:listenablefuture:1.0)
Go to the documentation to learn how to Fix dependency resolution errors.
我的
app/build.gradle中也有以下内容:implementation 'com.google.android.gms:play-services-base:16.1.0'
implementation 'com.google.android.gms:play-services-analytics:16.0.8'
implementation 'com.google.android.gms:play-services-awareness:16.0.0'
implementation 'com.google.android.gms:play-services-cast:16.2.0'
implementation 'com.google.android.gms:play-services-gcm:16.1.0'
implementation 'com.google.android.gms:play-services-location:16.0.0'
implementation 'com.google.android.gms:play-services-maps:16.1.0'
implementation 'com.google.firebase:firebase-core:16.0.8'
implementation 'com.google.firebase:firebase-iid:17.1.2'
implementation 'com.google.firebase:firebase-messaging:17.6.0'
implementation 'android.arch.work:work-runtime:1.0.1'
implementation 'com.android.support:multidex:1.0.3'
apply plugin: 'com.google.gms.google-services'
也许我正在使用的库之一已经包含对In-App Messaging依赖的支持，然后它变得多余了？谢谢你。

Google知道此错误，因此他们制作了一个特殊的程序包来解决冲突。
将此添加到您的build.gradle
implementation 'com.google.guava:listenablefuture:9999.0-empty-to-avoid-conflict-with-guava'
关于android - 在模块guava-20.0.jar中找到重复的com.google.common.util.concurrent.ListenableFuture类(com.google.guava :guava:20. 0)，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/56639529/
