你这个是Gradle 版本的问题。你的项目似乎需要 Gradle 7.4.2，但在你的环境中找不到这个版本。
在项目的 build.gradle 文件中，将 Gradle 版本升级到 7.4.2 或更新的版本。在 build.gradle 文件的 buildscript 部分，修改 Gradle 版本的声明，如下所示：

buildscript {
    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:7.4.2'
    }
}

然后尝试重新构建你的项目。
