Error in library built with jitpack: Unable to resolve dependency for ':app@debug/compileClasspath'

Question

I am trying to publish my android library on jitpack.io but when I tried to add dependency to test my artifact I am getting this error:

Unable to resolve dependency for ':app@debug/compileClasspath': Could not resolve com.github.pashaoleynik97:GSBarcodeScannerHelper:0.1.1-alpha.

My gradle files in library project are listed below.

My build.gradle (app):

apply plugin: 'com.android.application'

android {
    compileSdkVersion 28
    defaultConfig {
        applicationId "com.github.pashaoleynik97.gsbarcodescannerhelperdemo"
        minSdkVersion 21
        targetSdkVersion 28
        versionCode 2
        versionName "1.1"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    implementation fileTree(include: ['*.jar'], dir: 'libs')
    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 project(':gsbarcodescannerhelper')
}

My build.gradle (gsbarcodescannerhelper):

apply plugin: 'com.android.library'
group='com.github.pashaoleynik97;'

android {
    compileSdkVersion 28



    defaultConfig {
        minSdkVersion 21
        targetSdkVersion 28
        versionCode 2
        versionName "0.1.1"

        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"

    }

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

}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])

    implementation 'com.android.support:appcompat-v7:28.0.0'
    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 'org.jetbrains.kotlin:kotlin-stdlib:1.3.10'
    implementation(name: 'generalscan-sdk-1.0.6', ext:'aar')
}

And finally, my build.gradle (project):

buildscript {

    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.2.0'
        classpath 'com.github.dcendents:android-maven-gradle-plugin:1.4.1'

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

allprojects {
    repositories {
        google()
        jcenter()
        flatDir {
            dirs project(':gsbarcodescannerhelper').file('libs')
        }
        maven { url 'https://jitpack.io' }
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

I pushed my project on github, created release (through github web interface), then went to jitpack.io and published my library. But when I tried to add this library to my new test project I had errors (listed in top of this post). What I am doing wrong?

UPD

I also tried to add classpath 'com.github.dcendents:android-maven-gradle-plugin:2.1' like in this docs: https://jitpack.io/docs/ANDROID/ But result remains the same.

UPD 2

Created issue: https://github.com/jitpack/jitpack.io/issues/3758

Answer 1

This seems to be a persisting issue for a few days, can be found here, the link mentions a workaround here. The workaround is to add www with the jitpack.io. Hence update it to the following:

maven { url 'https://www.jitpack.io' }
