i am trying android WorkManager, The code is throwing error "More than one file was found with OS independent path 'META-INF/proguard/androidx-annotations.pro" when running, I tried the following answer, it was not helpful.

WorkManager依赖关系

build.gradle(app)

apply plugin: 'com.android.application'

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'
        }
    }


}

dependencies {
    def work_version = "1.0.0-alpha09"
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.android.support:appcompat-v7:28.0.0'
    implementation 'com.android.support.constraint:constraint-layout:1.1.3'
    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'
    implementation "android.arch.work:work-runtime:$work_version"
}

推荐答案

这是目前已知的问题，《架构组件发行说明》 概述了该问题，并提供了解决方案，直到工作管理器库的 alpha10 版本发布为止:

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

如果遇到以下问题:使用操作系统独立路径'META-INF/proguard/androidx-annotations.pro'找到了多个文件"，请将以下内容作为临时解决方法放在gradle文件中，我们在alpha10中修复了该问题:

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'
    }
}

该问题应在WorkManager的 1.0.0-alpha10 版本中正确解决.

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