I was searching for how to publish Android library on MavenCentral() and it turned out the process seems very complicated and troublesome. So I found another easy method is to publish my Android library on instead.

Although it is simple, I still spent my whole day to figure that out. It is mainly due to the tutorials out there (even the official documentation) are missing information and not beginner-friendly enough.

So, I'm going to share the step-by-step guides how to do it and hopefully this can save you a lot of your time.

1. Create a New Project

  • Go to File -> New -> New Project...
  • Choose either Empty Activity or Empty Compose Activity, click Next
  • Update Name and Save Location
  • Click Finish

2. Create a New Module

  • Go to File -> New -> New Module...
  • Select Android Library, update Module Name and Package Name
  • Click Finish

3. Add Code Into Your Module

The module should be created at the root project folder.

  • Go to the package, right click, select New -> Kotlin Class/File

  • Implement this code as an example
package com.vtsen.sydneysuburbs

object Sydney {
    val suburbs = listOf("Ryde", "Chippendale")

4. Use the Local Module

In order to use the module that you just created,

  • Add implementation project(':<Module_Name>') dependency in the build.gradle (app level) file.
dependencies {
    implementation project(':SydneySuburbs')
  • Access / use the code that you created in step 3 above. E.g. Sydney.suburbs[0]
import com.vtsen.sydneysuburbs.Sydney
    // Example of accessing SydneyBurbs module
    Surface(color = MaterialTheme.colors.background) {
  • Run your app, it should work!

5. Setup and Configure for

  • Add maven-publish plugin in build.gradle file (module level).
plugins {
    id 'maven-publish'

Note: There are 3 build.gradle files - project level, app level and module level (the module you just created). Please make sure you update the correct build.gradle file.

  • Add afterEvaluate at the end of the build.gradle file (module level)
afterEvaluate {
    publishing {
        publications {
            release(MavenPublication) {
                from components.release

                groupId = 'com.github.vinchamp77'
                artifactId = 'demo-simple-android-lib'
                version = '0.0.0'
  1. groupId = com.github.<Your_GitHub_User_Name>
  2. artifactId = '<Your_GitHub_Repository_Name>'
  • Switch to project mode, add the jitpack.yml in project root folder

The content in jitpack.yml:

  - openjdk11

6. Share Project on GitHub

Now, it is ready to upload your projects to GitHub repository.

You can also clean up unused dependencies before you upload your project to GitHub. This can help save the build time when builds your project.

  • Follow the detailed steps below if you don't know how to do it
  • Please make sure the repository name match the artifactId in step 5 and uncheck the private check box

7. Sign Up JitPack

  • Go to, click the Sign In button at the top left
  • Authorize JitPack to allow JitPack accessing to your GitHub account

  • Select your repository and click Look Up. You should see the following:

8. Create a New Release to Trigger JitPack Build

  • Go to your repository, click Releases at the right.
  • Click Create a New Release
  • Click Chose a tag, enter the same version that you specify in step 4
  • Press enter
  • Click Publish release

9. Monitor JitPack Build

  • Go back to, and click Look Up.
  • While file a while, you should see the Log icon is build in progress.

  • When the build is done, you should see something like this:

Note: If the build failed, you should see the red report. If it passes, you should see the green report above.

  • Click on the green report, you should see something like this at the end.

10. Import JitPack Android Library

Once the JitPack has successfully built your Android library, it is ready to import your Android library to your project from

Note: I'm using the same project that I use to create this Android library as an example.

  • In settings.gradle, add maven { url '' }
dependencyResolutionManagement {
    repositories {

        maven { url '' }

Note: If you add this in build.gradle (project level), it won't work. You must add it in the settings.gradle instead.

  • In build.gradle (app level), replace implementation project(':SydneySuburbs') with implementation 'com.github.<github_user_name>:<repository_name>:<version_name>'
dependencies {
    implementation 'com.github.vinchamp77:demo-simple-android-lib:0.0.0'
  • Now, your project can import the Android library package and start using it. For example:
import com.vtsen.sydneysuburbs.Sydney


Some feedbacks that I get from twitter that some people in the community won't even consider your library if it's not on mavenCentral(). So it is worth to consider publishing to mavenCentral().

Well, I want to, but if you have any easy to follow tutorial, please let me know. For learning and beginner purpose, is good enough for me, at least for now. It is easy and simple to set it up.
