Hi I have a problem with com.github.PhilJay:MPAndroidChart library I want to add to my project when I sync my project everything is ok but when I compile my project it appears this error and I don't know why.

The problem says: More than one file was found with OS independent path 'META-INF/proguard/androidx-annotations.pro'

It supposed that I put everything in the right place

build.gradle (Module app)

 apply plugin: 'com.android.application'

android 
 compileSdkVersion 28
 defaultConfig 
 applicationId "company.eduardo.administradorfinanzas"
 minSdkVersion 21
 targetSdkVersion 28
 versionCode 1
 versionName "1.0"
 testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
 javaCompileOptions 
 annotationProcessorOptions 
 arguments = ["room.schemaLocation": "$projectDir/schemas".toString()]
 
 
 
 buildTypes 
 release 
 minifyEnabled false
 proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
 
 


repositories 
 jcenter()
 maven url 'https://jitpack.io' 


dependencies 
 implementation fileTree(dir: 'libs', include: ['*.jar'])
 implementation 'com.github.PhilJay:MPAndroidChart:v3.1.0-alpha'
 //noinspection GradleCompatible
 implementation 'com.android.support:appcompat-v7:28.0.0'
 implementation 'com.android.support:cardview-v7:28.0.0'
 implementation 'com.android.support:design: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 'com.google.android.gms:play-services-auth:16.0.1'
 implementation 'com.github.bumptech.glide:glide:4.8.0'
 implementation 'android.arch.persistence.room:runtime:1.1.1'
 annotationProcessor 'android.arch.persistence.room:compiler:1.1.1'

 // Room components
 implementation "android.arch.persistence.room:runtime:$rootProject.roomVersion"
 annotationProcessor "android.arch.persistence.room:compiler:$rootProject.roomVersion"
 androidTestImplementation "android.arch.persistence.room:testing:$rootProject.roomVersion"

// Lifecycle components
 implementation "android.arch.lifecycle:extensions:$rootProject.archLifecycleVersion"
 annotationProcessor "android.arch.lifecycle:compiler:$rootProject.archLifecycleVersion"

apply plugin: 'com.google.gms.google-services'

And my build.gradle (Project)

 // Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript 

 repositories 
 google()
 jcenter()
 
 dependencies 
 classpath 'com.android.tools.build:gradle:3.2.1'
 classpath 'com.google.gms:google-services:4.0.1'

 // NOTE: Do not place your application dependencies here; they belong
 // in the individual module build.gradle files
 


allprojects 
 repositories 
 google()
 jcenter()
 


task clean(type: Delete) 
 delete rootProject.buildDir


ext 
 roomVersion = '1.1.1'
 archLifecycleVersion = '1.1.1'

either use a stable version:

dependencies 
 // implementation fileTree(dir: "libs", include: ["*.jar"])
 implementation "com.github.PhilJay:MPAndroidChart:v3.0.2"

or limit the duplicate androidx-annotations.pro to one entry:

android 
 packagingOptions 
 pickFirst "META-INF/proguard/androidx-annotations.pro"
 

also check the libs directory, if not the duplicate entry originates from a *.jar, because file androidx-annotations.pro sounds as if it were a ProGuard consumer rules file, as it is often being provided by a library. and the google-services plugin currently would be at version 4.1.0.
