背景信息 #

• 应用创建于2020/21年，此前已升级过API级别，本次再次升级时触发该问题
• 已知JCenter已关闭，查阅过官方相关说明及2021、2023年的同类问题，未找到有效解决方法
• 已为多个模块添加namespace配置

修复方案 #

1. 修复buildscript嵌套错误 #

你的根build.gradle存在buildscript嵌套buildscript的无效写法，这会导致依赖配置无法被正确识别。需要删除内层嵌套的buildscript块，将内容合并到外层。

2. 替换JCenter为有效仓库 #

JCenter已停止服务，需将mavenCentral()添加到buildscript和allprojects的repositories中，替换或移除jcenter()。com.eightbitlab:blurview的新版本已迁移至mavenCentral，确保仓库配置正确。

3. 调整blurview依赖的位置 #

com.eightbitlab:blurview是应用级依赖，不属于buildscript的classpath依赖，必须移至模块级build.gradle（如app/build.gradle）的dependencies块中，而非根项目的buildscript内。

修正后的根build.gradle示例 #

buildscript {
    ext {
        buildToolsVersion = "30.0.3"
        minSdkVersion = 21
        compileSdkVersion = 34
        targetSdkVersion = 34
    }
    repositories {
        google()
        mavenCentral() // 替换jcenter()，或保留jcenter并添加内容过滤
        // 若必须保留jcenter，可添加过滤仅允许特定依赖：
        // jcenter {
        //     content {
        //         includeGroupByRegex 'com\\.eightbitlab.*'
        //     }
        // }
    }
    dependencies {
        classpath("com.android.tools.build:gradle:8.0.0")
        // 注意：blurview依赖不应出现在此处
    }
}

allprojects {
    repositories {
        mavenLocal()
        mavenCentral()
        maven {
            url("$rootDir/../node_modules/react-native/android")
        }
        maven {
            url("$rootDir/../node_modules/jsc-android/dist")
        }
        google()
        maven { url 'https://www.jitpack.io' }
        // 同样替换jcenter为mavenCentral，或按需过滤
    }
}

4. 在模块级build.gradle中添加依赖 #

打开app/build.gradle，在dependencies块内添加：

implementation 'com.eightbitlab:blurview:1.6.3'
// 可选：尝试升级到最新兼容版本，如1.7.2
// implementation 'com.eightbitlab:blurview:1.7.2'

5. 同步并清理缓存 #

• 执行Gradle同步操作（Android Studio中点击"Sync Project with Gradle Files"）
• 运行命令清理缓存并重新构建：

  # Windows
  gradlew.bat clean build --refresh-dependencies
  
  # macOS/Linux
  ./gradlew clean build --refresh-dependencies
