Android 在模块 guava20.0.jar (com.google.guava：guava：20.0) 中发现重复的类 com.google.common.util.concurrent.ListenableFuture

当我在app/build.gradle中使用implementation 'com.google.firebase:firebase-inappmessaging-display:17.2.0'时，会出现以下错误:

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.

在我的app/build.gradle岁生日中，我还有以下几点:

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'

也许我正在使用的其中一个库已经包含了对应用内消息依赖性的支持，然后它就变得多余了？非常感谢.
