Possible solution:

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

解决步骤 #

1. 补全仓库配置 #

如果是新版Gradle项目（使用pluginManagement），修改settings.gradle文件，确保包含必要仓库：

pluginManagement {
    repositories {
        google()
        mavenCentral()
        gradlePluginPortal()
    }
}
dependencyResolutionManagement {
    repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
    repositories {
        google()
        mavenCentral()
    }
}
rootProject.name = "My Application"
include ':app'

如果是旧版项目，在根build.gradle中添加buildscript块配置仓库：

buildscript {
    repositories {
        google()
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:7.4.0'
    }
}

plugins {
    id 'com.android.application' version '7.4.0' apply false
    id 'com.android.library' version '7.4.0' apply false
}

2. 排查网络问题 #

• 确认网络可正常访问Google Maven仓库，若无法访问可切换国内镜像（如阿里云）
• 关闭代理、VPN，避免网络拦截

3. 清理Gradle缓存 #

• 关闭Android Studio
• 删除本地Gradle缓存目录：
  • Windows：C:\Users\<你的用户名>\.gradle\caches
  • Mac/Linux：~/.gradle/caches
• 重新打开Studio，点击File -> Sync Project with Gradle Files

4. 匹配Gradle与插件版本 #

Android Gradle插件7.4.0对应Gradle 7.5版本，检查gradle/wrapper/gradle-wrapper.properties：

distributionUrl=https\://services.gradle.org/distributions/gradle-7.5-bin.zip

版本不匹配则修改后同步项目。

5. 配置国内镜像（可选） #

若无法访问Google仓库，在settings.gradle替换为阿里云镜像：

pluginManagement {
    repositories {
        maven { url 'https://maven.aliyun.com/repository/google' }
        maven { url 'https://maven.aliyun.com/repository/public' }
        gradlePluginPortal()
    }
}
dependencyResolutionManagement {
    repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
    repositories {
        maven { url 'https://maven.aliyun.com/repository/google' }
        maven { url 'https://maven.aliyun.com/repository/public' }
    }
}
