Take a look at https://issuetracker.google.com/issues/116154359.
看看https://issuetracker.google.com/issues/116154359。
The workaround is:
解决方法是：
implementation("android.arch.work:work-runtime:1.0.0-alpha09") {
exclude group: 'com.google.guava', module: 'listenablefuture'
}

In my case, I had to add the following configurations to app's module build.gradle:
就我而言，我必须将以下配置添加到 app 的模块中build.gradle：
configurations {
all*.exclude group: 'com.google.guava', module: 'listenablefuture'
}
It happens because some dependencies use com.google.guava:guavaand com.google.guava:listenablefuturetogether. It causes a dependency conflict.
发生这种情况是因为某些依赖项一起使用com.google.guava:guava和com.google.guava:listenablefuture。它会导致依赖冲突。

I merely added implementation 'com.google.guava:guava:27.0.1-android'at the end of my app gradle file and the error went away.
我只是implementation 'com.google.guava:guava:27.0.1-android'在我的应用程序 gradle 文件的末尾添加，错误就消失了。

I am using ListenableFuturethat comes from the work manager.
我正在使用ListenableFuture来自工作经理的。
implementation("android.arch.work:work-runtime:1.0.0")
So excluding exclude group: 'com.google.guava', module: 'listenablefuture', didn't work for me.
所以排除exclude group: 'com.google.guava', module: 'listenablefuture'，对我不起作用。
I was using a dependency that internally used androidTestImplementation "com.google.truth:truth:42"that internally used com.google.guava:guava:25.0.1-android. This was causing the problem for me.
我正在使用内部使用的依赖项androidTestImplementation "com.google.truth:truth:42"，内部使用的com.google.guava:guava:25.0.1-android. 这给我造成了问题。
Upgrading com.google.truth:truthto 43solved it for me.
升级com.google.truth:truth到43解决了这个问题对我来说。
