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" } 

 


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:

Known Issue

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'      }  } 

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'     } } 

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