How to correctly include a maven dependency

Hi.

I’m trying to import this maven dependency in my build.gradle.

The dependency should be defined, as the GitHub readme points out:

repositories {
  // releases
  mavenCentral()
  // snapshots
  maven {
    url "https://repo.spongepowered.org/repository/maven-public/"
  }
}

dependencies {
  implementation "org.spongepowered:noise:2.0.0-SNAPSHOT"
}

My build.gradle is generated by a tool since this is supposed to be a LibGDX game. So I don’t know how to read the script. This is the build.gradle:

buildscript {
    

    repositories {
        mavenLocal()
        mavenCentral()
        gradlePluginPortal()
        maven { url "https://oss.sonatype.org/content/repositories/snapshots/" }
        google()
    }
    dependencies {
        classpath 'org.wisepersist:gwt-gradle-plugin:1.0.13'
        classpath 'org.gretty:gretty:3.0.2'
    }
}

allprojects {
    apply plugin: "eclipse"

    version = '1.0'
    ext {
        appName = "Kingdoms of Cavva"
        gdxVersion = '1.10.0'
        roboVMVersion = '2.3.12'
        box2DLightsVersion = '1.5'
        ashleyVersion = '1.7.3'
        aiVersion = '1.8.2'
        gdxControllersVersion = '2.1.0'
    }

    repositories {
        mavenLocal()
        mavenCentral()
        google()
        gradlePluginPortal()
        maven { url "https://oss.sonatype.org/content/repositories/snapshots/" }
        maven { url "https://oss.sonatype.org/content/repositories/releases/"  }
    }
}

project(":desktop") {
    apply plugin: "java-library"


    dependencies {
        implementation project(":core")
        api "com.badlogicgames.gdx:gdx-backend-lwjgl:$gdxVersion"
        api "com.badlogicgames.gdx:gdx-platform:$gdxVersion:natives-desktop"
        api "com.badlogicgames.gdx:gdx-tools:$gdxVersion"
        api "com.badlogicgames.gdx:gdx-box2d-platform:$gdxVersion:natives-desktop"
        
    }
}

project(":core") {
    apply plugin: "java-library"

    dependencies {
        api "com.badlogicgames.gdx:gdx:$gdxVersion"
        api "com.badlogicgames.gdx:gdx-ai:$aiVersion"
        api "com.badlogicgames.box2dlights:box2dlights:$box2DLightsVersion"
        api "com.badlogicgames.gdx:gdx-box2d:$gdxVersion"
    }
}

project(":html") {
    apply plugin: "java-library"
    apply plugin: "gwt"
    apply plugin: "war"
    apply plugin: "org.gretty"


    dependencies {
        implementation project(":core")
        api "com.badlogicgames.gdx:gdx-backend-gwt:$gdxVersion"
        api "com.badlogicgames.gdx:gdx:$gdxVersion:sources"
        api "com.badlogicgames.gdx:gdx-backend-gwt:$gdxVersion:sources"
        api "com.badlogicgames.gdx:gdx-ai:$aiVersion:sources"
        api "com.badlogicgames.box2dlights:box2dlights:$box2DLightsVersion:sources"
        api "com.badlogicgames.gdx:gdx-box2d:$gdxVersion:sources"
        api "com.badlogicgames.gdx:gdx-box2d-gwt:$gdxVersion:sources"
        
    }
}

I don’t get where I should put maven dependencies in the script. Can someone help me, please? Thanks in advance.
