'Failed to resolve: com.github.barteksc:android-pdf-viewer:2.8.1

I am trying use this library in my Project. But i am unable to download it by adding it in gradle build. In fact i am even unable to download any library through gradle. I need to manually download a jar file and add that as a library. But in this case I couldn't find the jar file for PDFviewer.

Build.gradle (Module)

dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
    exclude group: 'com.android.support', module: 'support-annotations'
})
compile 'com.android.support:appcompat-v7:25.1.1'
compile 'com.android.support:design:23.0.1'
testCompile 'junit:junit:4.12'
compile files('libs/jsoup-1.8.1.jar')
compile files('libs/log4j-1.2.9.jar')
compile files('libs/picasso-2.5.2.jar')
compile files('libs/json-simple-1.1.jar')
compile files('libs/glide-3.7.0.jar')
compile files('libs/commons-codec-1.9.jar')
compile files('libs/asmack.jar')
compile files('libs/android-logging-log4j-1.0.3.jar')
compile 'com.github.barteksc:android-pdf-viewer:2.8.1'  //unable to add this.
}

Build.gradle

allprojects {
repositories {
    jcenter()
    maven {
        url "https://maven.google.com"
    }
   // google()  
   // mavenLocal() // tried everything
}
}

I have tried almost everything for the past three days given in SO but still couldn't find any solution to this. It will be helpful even if i get the jar file.

Solution 1:^[1]

You should add

repositories 
   {
      maven { url "http://jcenter.bintray.com" }
   }

Solution 2:^[2]

it's a problem with jCenter (deprecated) when he's drop.

add :

allprojects {repositories {
        mavenCentral()
        google()
        gradlePluginPortal()
    }
}

Solution 3:^[3]

Simply add this line into the build.gradle(app level)

implementation 'com.github.barteksc:android-pdf-viewer:2.8.2'

If you have android studio bumblebee or android studio arctic fox then,

add gradlePluginPortal() into settings.gradle file

dependencyResolutionManagement {
    repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
    repositories {
        google()
        mavenCentral()
        gradlePluginPortal()
    }
}

Solution 4:^[4]

Add the maven URL and GitHub dependencies...

You might turn on your internet connection for Gradle to download necessary dependencies...

Solution 5:^[5]

Make sure adding this to your allprojects repositories like this inside android\build.gradle file: do not forget that it should be SSL secured using https://

repositories
   {
     maven {
        url ("https://jcenter.bintray.com")
     }
   }

Solution 6:^[6]

Simply add this line into the build.gradle(app level)

implementation 'com.github.barteksc:android-pdf-viewer:2.8.2'

If you have android studio bumblebee or android studio arctic fox then,

add gradlePluginPortal() into settings.gradle file

dependencyResolutionManagement {
    repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
    repositories {
        google()
        mavenCentral()
        gradlePluginPortal()
