解决步骤 #

1. 修复expo-ads-admob的classifier属性错误 #

Gradle 7.0+ 废弃了Jar任务的classifier属性，改用archiveClassifier，需修改依赖的构建配置：

• 安装补丁工具：

  npm install patch-package --save-dev
  

• 打开node_modules/expo-ads-admob/android/build.gradle，找到第40行的classifier = 'sources'，替换为：

  archiveClassifier = 'sources'
  

• 生成并保存补丁：

  npx patch-package expo-ads-admob
  

2. 修复expo项目的release组件错误 #

该问题多由Gradle版本与Expo模块不兼容导致，执行以下操作：

• 检查android/build.gradle中的Gradle版本，确保与当前Expo SDK版本匹配（比如Expo SDK 49对应Gradle 7.5及以上）
• 清理缓存并重建项目：

  rm -rf node_modules package-lock.json yarn.lock
  npm install
  npx expo prebuild --clean
  

• 若使用EAS构建，确认eas.json中配置的Gradle版本符合要求
