推荐答案

这是目前已知的问题，Architecture Components Release Notes 概述了问题并提供了解决方案，直到 alpha10 版本的工作管理器库:

This is a known problem at the moment, Architecture Components Release Notes outline the issue and provides a solution to fix it until alpha10 version of work manager library:

已知问题

如果您遇到以下问题:发现多个文件与操作系统独立路径‘META-INF/proguard/androidx-annotations.pro’"，请将以下内容放入您的 gradle 文件中作为临时解决方法，同时我们在 alpha10 中修复了这个问题:

If you run into the following issue: "More than one file was found with OS independent path 'META-INF/proguard/androidx-annotations.pro'", please put the following in your gradle file as a temporary workaround while we fix the issue in alpha10:

 android {
     packagingOptions {
         exclude 'META-INF/proguard/androidx-annotations.pro'
     }
 }

因此，在您的情况下，android 部分应如下所示:

So, in your case, android section should be like following:

android {
    compileSdkVersion 28
    defaultConfig {
        applicationId "rock.dmx.xaro.workmanagerexample"
        minSdkVersion 19
        targetSdkVersion 28
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }

    // Temporary fix until alpha10
    packagingOptions {
        exclude 'META-INF/proguard/androidx-annotations.pro'
    }
}

应该在 1.0.0-alpha10 版本的 WorkManager 中正确解决问题.

Issue should be addressed properly in 1.0.0-alpha10 version of WorkManager.
