我正在尝试升级我的build gradle版本，但我遇到了错误。这是我的Gradle：

repositories {
        google()
        mavenCentral()
        jcenter()
        maven { url 'https://jitpack.io' }
    }
dependencies {
        classpath 'com.android.tools.build:gradle:7.4.2'
        classpath 'com.google.gms:google-services:4.3.13'
    }

这是Gradle Wrapper：distributionUrl=https：services.gradle.org/distributions/gradle-7.4.2-all.zip
它已经下载了gradle-7.4.2-all.zip但它没有下载gradle：7.4.2.这就是错误

Could not find com.android.tools.build:gradle:7.4.2.
Searched in the following locations:
  - https://dl.google.com/dl/android/maven2/com/android/tools/build/gradle/7.4.2/gradle-7.4.2.pom
  - https://repo.maven.apache.org/maven2/com/android/tools/build/gradle/7.4.2/gradle-7.4.2.pom
  - https://jcenter.bintray.com/com/android/tools/build/gradle/7.4.2/gradle-7.4.2.pom
  - https://jitpack.io/com/android/tools/build/gradle/7.4.2/gradle-7.4.2.pom

我该怎么办？
