creating android library on jitpack error

Question

I am following tutorial: https://medium.com/@anujguptawork/how-to-create-your-own-android-library-and-publish-it-750e0f7481bf

to create android library. Everything works fine, but when I go to Jitpack, script under "LOG" has red color. This means there is error and I am unable to use m library in android projects.

This is what the script says when I open it:

Does anyone know how to fix this?

Answer 1

What went wrong: Plugin [id: 'com.android.library'] was not found in any of the following sources:

You should use below

plugins {
    id 'com.android.library'
    id 'android-maven'
    id 'kotlin-android'
    id 'kotlin-android-extensions'
}

FYI

Make sure the library is listed at the top of your settings.gradle file, as shown here for a library named "testLib":

include ':app', ':testLib'

Then open the app module's build.gradle file and add a new line to the dependencies block as shown in the following snippet:

dependencies {
    implementation project(":testLib")
}
