While generating signed APK, "androidx.legacy_legacy-support-core-utils.version collided" error occurs

Question

While trying to generate signed APK it shows the following error message.

Entry name 'META-INF/androidx.legacy_legacy-support-core-utils.version' collided

Previously it was working correctly for couple of years. Additionally i have checked in another PC with same android studio and same gradle version, it is working correctly in that PC. I am experiencing this issue in particular one PC itself why? I have attached the build.gradle below.

apply plugin: 'com.android.application'

android {
    compileSdkVersion 29

    defaultConfig {
        minSdkVersion 19
        targetSdkVersion 29
        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
        multiDexEnabled true
        vectorDrawables {
            useSupportLibrary = true
        }
    }

        compileOptions {
            sourceCompatibility JavaVersion.VERSION_1_8
            targetCompatibility JavaVersion.VERSION_1_8
        }


    //--Test
    lintOptions {
        checkReleaseBuilds false
    }



    flavorDimensions "default"



    buildTypes {
        publicDebug {
            minifyEnabled false
            initWith debug
            //shrinkResources true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'


        }



        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'

        }
    }

    sourceSets {
        main {
            res.srcDirs =
                    [

Kindly anyone help to solve this. Where i missed out anything?

Answer 1

I found the origin of issue. It was in the output.json. It is the culprit. That file corrupted due to some activities. We have to delete the file from the destination folder of Signed APK generation. It fixed the issue.

Answer 2

It worked for me by editing app/build.gradle

packagingOptions {
    exclude 'META-INF/androidx.legacy_legacy-support-core-utils.version'
    // or exclude 'META-INF/*'
}

or delete app/build directory
