Firebase安装程序在根级(项目级)Gradle文件(<project>/build.Gradle.kts)上缺少插件

他们说,当我要建立我的firebase项目时,我遵循了firebase的介绍 但我在根级build.gradle文件中找不到这样的插件。下面的代码是我的build.gradle文件,

有任何独奏加上它,

buildscript {
    ext.kotlin_version = '1.7.10'
    repositories {
        google()
        mavenCentral()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:7.3.0'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    }
}

allprojects {
    repositories {
        google()
        mavenCentral()
    }
}

rootProject.buildDir = '../build'
subprojects {
    project.buildDir = "${rootProject.buildDir}/${project.name}"
}
subprojects {
    project.evaluationDependsOn(':app')
}

tasks.register("clean", Delete) {
    delete rootProject.buildDir
}

我正在努力( Where do I add repositories in my root-level build.gradle file? 这种解决方案),但对我来说不起作用。

当我添加到下面的中时,就像它给出了错误一样,

buildscript {
    ext.kotlin_version = '1.7.10'
    repositories {
        google()
        mavenCentral()
    }


    dependencies {
        classpath 'com.android.tools.build:gradle:7.3.0'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    }
}

plugins {

    id("com.google.gms.google-services") version "4.4.0" apply false

}

allprojects {
    repositories {
        google()
        mavenCentral()
    }
}

rootProject.buildDir = '../build'
subprojects {
    project.buildDir = "${rootProject.buildDir}/${project.name}"
}
subprojects {
    project.evaluationDependsOn(':app')
}

tasks.register("clean", Delete) {
    delete rootProject.buildDir
}

这是一个这样的错误,

在以下任何来源中都找不到插件[id:“com.google.gms.google services”,版本:“4.4.0”,apply:false]:
