Gradle duplicate entry error: META-INF/MANIFEST.MF (Or how to delete a file from jar)

Question

I've cloned a github repository because I wanted to study the code, but when I tried to build it in Android Studio, I ran into some trouble. After adding the google maven repository (as prompted by Android Studio) and updating both the Gradle Plugin Version and the Grade Version (to 3.5.2 and to 5.4.1, respectively), the build fails because of the following error:

Cause: duplicate entry: META-INF/MANIFEST.MF

And this, to be more specific:

Caused by: java.util.zip.ZipException: duplicate entry: META-INF/MANIFEST.MF

Here is my project level build.gradle file:

    buildscript {
        repositories {
            jcenter()
            google()
        }
    
        dependencies {
            classpath 'com.android.tools.build:gradle:3.5.2'
    
            // NOTE: Do not place your application dependencies here; they belong
            // in the individual module build.gradle files
        }
    }
    
    allprojects {
        repositories {
            jcenter()
    
            maven {
                url 'https://maven.google.com'
            }
    
        }
    }

Here's my module build.gradle file (before trying anything):

    apply plugin: 'com.android.application'
    
    android {
        compileSdkVersion 22
        buildToolsVersion '28.0.3'
    
        defaultConfig {
            applicationId "com.thelittlenaruto.supportdesignexample"
            minSdkVersion 11
            targetSdkVersion 22
            versionCode 1
            versionName "1.0"
        }
    
        buildTypes {
            release {
                minifyEnabled false
                proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
            }
        }
    }
    
    dependencies {
        implementation fileTree(dir: 'libs', include: ['*.jar'])
        implementation ('com.android.support:appcompat-v7:22.2.1')
        implementation ('com.android.support:design:22.2.1')
        implementation 'com.github.frankiesardo:linearlistview:1.0.1@aar'
    }

Here's what I've tried so far:

• Adding the following to the android section of my module build.gradle file:

    sourceSets {
            main{
                java{
                    exclude '**/META-INF/MANIFEST'
                    exclude '**/META-INF/MANIFEST.MF'
                    exclude 'META-INF/MANIFEST'
                    exclude 'META-INF/MANIFEST.MF'
                    exclude '!META-INF/MANIFEST.MF'
                }
            }
        }

• Adding this:

    sourceSets.main.res.filter.exclude 'META-INF/MANIFEST'
        sourceSets.main.res.filter.exclude 'META-INF/MANIFEST.MF'

• Also this:

    packagingOptions {
            apply plugin: 'project-report'
            exclude '**/META-INF/MANIFEST'
            exclude '**/META-INF/MANIFEST.MF'
            exclude 'META-INF/MANIFEST'
            exclude 'META-INF/MANIFEST.MF'
            exclude '!META-INF/MANIFEST.MF'
        }

• And this:

    packagingOptions {
            pickFirst '**/META-INF/MANIFEST'
            pickFirst '**/META-INF/MANIFEST.MF'
            pickFirst 'META-INF/MANIFEST'
            pickFirst 'META-INF/MANIFEST.MF'
            pickFirst '!META-INF/MANIFEST.MF'
        }

• This:

    aaptOptions {
            ignoreAssetsPattern "!META-INF/MANIFEST.MF"
            ignoreAssetsPattern "META-INF/MANIFEST.MF"
        }

I think I've tried mostly everything in this question: How to exclude certain files from Android Studio gradle builds?

Nothing worked.

After searching for a solution, I think the problem is that I have duplicated dependencies. So I've tried the following:

    dependencies {
        implementation fileTree(dir: 'libs', include: ['*.jar'])
        implementation ('com.android.support:appcompat-v7:22.2.1'){
            exclude module: 'support-v4'
        }
        implementation ('com.android.support:design:22.2.1')
        implementation 'com.github.frankiesardo:linearlistview:1.0.1@aar'
    }

And this:

    dependencies {
        implementation fileTree(dir: 'libs', include: ['*.jar'])
        implementation ('com.android.support:design:22.2.1'){
            exclude module: 'support-v7'
        }
        implementation 'com.github.frankiesardo:linearlistview:1.0.1@aar'
    }

I still get the same error.

What am I doing wrong?

Answer 1

I was facing the same issue in Android Studio Giraffe,

I delete Build folder and rebuild will fix the issue for me.

Go to project view -> Build

Answer 2

as @rubo77 says and after my confirmation:

• Latest solution
  • Upgrade gradle version
    • eg:
      • from 3.5.2 to 3.5.3
      • from 3.5.2 to 3.5.4
• Obsolete solution:
  • downgrade from 3.5.2 to 3.5.1

my choice is : upgrade from 3.5.2 to 3.5.4

build.gradle:

    dependencies {
//        classpath 'com.android.tools.build:gradle:3.5.2'
//        classpath 'com.android.tools.build:gradle:3.5.3'
        classpath 'com.android.tools.build:gradle:3.5.4'
    }

Answer 3

Either package it once or not at all:

android {
    packagingOptions {
        pickFirst "META-INF/MANIFEST.MF"
        // exclude "META-INF/MANIFEST.MF"
    }
}

Answer 4

Set project dependencies to:

classpath 'com.android.tools.build:gradle:3.5.3'

or latest one.

Note: by doing this, my problem has been resolved.

Answer 5

This issue is happening because of duplicate dependencies.
Check for multiple dependencies in the Gradle app.

Answer 6

As Rajen Raiyarela said, go to File->Project Structure->Project->Android Gradle Plugin Version and downgrade it from 3.5.2 to 3.5.1.
