the devlight.io:navigationtabbar:1.2.5 dependency is now stored at https://repo.grails.org, specifically at https://repo.grails.org/ui/native/core/devlight/io/navigationtabbar/1.2.5/navigationtabbar-1.2.5.pom

Below is my example codes to get the dependency working.

in build.gradle(app level):

implementation 'devlight.io:navigationtabbar:1.2.5'

in settings.gradle:

pluginManagement {
    repositories {
        google()
        mavenCentral()
        gradlePluginPortal()
        maven { url 'https://jcenter.bintray.com' }
        maven { url 'https://jitpack.io' }
        maven { url "https://repo.grails.org/grails/core" } 
    }
}
dependencyResolutionManagement {
    repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
    repositories {
        google()
        mavenCentral()
        maven { url "https://repo.grails.org/grails/core" } 
        maven { url 'https://jitpack.io' }
        maven { url 'https://jcenter.bintray.com' }
    }
}
rootProject.name = "xxx"
include ':app'

and in build.gradle(Project level):

buildscript {
    repositories {
        mavenCentral()
        google()
    }
    dependencies {
        classpath 'com.github.dcendents:android-maven-gradle-plugin:1.5'
        classpath "com.jfrog.bintray.gradle:gradle-bintray-plugin:1.7.3"
        classpath 'com.android.tools.build:gradle:3.1.2'
    }
}

plugins {
    id 'com.android.application' version '8.3.1' apply false
    id 'com.android.library' version '8.3.1' apply false
}
