我在android studio中的项目级build.gradle文件中收到此警告。

Warning:(22, 9) JCenter Maven repository is no longer receiving updates: newer library versions may be available elsewhere

做该做的事。我试着删除它，得到了一个很长的错误列表，如下所示。

> Could not resolve all files for configuration ':classpath'.
   > Could not find org.jetbrains.kotlin:kotlin-stdlib-jdk8:1.7.10.
     Searched in the following locations:
       - https://dl.google.com/dl/android/maven2/org/jetbrains/kotlin/kotlin-stdlib-jdk8/1.7.10/kotlin-stdlib-jdk8-1.7.10.pom
     If the artifact you are trying to retrieve can be found in the repository but without metadata in 'Maven POM' format, you need to adjust the 'metadataSources { ... }' of the repository declaration.

     If the artifact you are trying to retrieve can be found in the repository but without metadata in 'Maven POM' format, you need to adjust the 'metadataSources { ... }' of the repository declaration.....

可能的解决方案如下：

Possible solution:
 - Declare repository providing the artifact, see the documentation at https://docs.gradle.org/current/userguide/declaring_repositories.html

我该怎么做才能解除警告？
这是我的项目级build.gradle，在这里我得到了警告：

buildscript {

    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:7.4.2'
        classpath 'com.google.gms:google-services:4.3.15'
        
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        google()
        jcenter()
    }
}
