github上的安卓液态动画问题

问题遇到的现象和发生背景

请问这个液态动画的代码应该写入哪个build.gradl文件里面

用代码块功能插入代码，请勿粘贴截图

def githubProperties = new Properties()
githubProperties.load(new FileInputStream(rootProject.file("github.properties")))
repositories {
    maven {
        name = "GitHubPackages"

        url = uri("https://maven.pkg.github.com/Cuberto/liquid-swipe-android")
        credentials {
            /** Create github.properties in root project folder file with     
            ** gpr.usr=GITHUB_USER_ID & gpr.key=PERSONAL_ACCESS_TOKEN 
            ** Or set env variable GPR_USER & GPR_API_KEY if not adding a properties file**/
            username = githubProperties['gpr.usr'] ?: System.getenv("GPR_USER")
            password = githubProperties['gpr.key'] ?: System.getenv("GPR_API_KEY")
        }
    }
}
