执行npm run build时expo-firebase-core项目评估报错求助

我创建了一个Expo项目并集成了Firebase谷歌认证功能，执行npm run build时出现以下错误：

评估项目':expo-firebase-core'时出现问题。

无法为类型为org.gradle.api.tasks.bundling.Jar的任务':expo-firebase-core:androidSourcesJar'设置未知属性'classifier'。

项目依赖如下：

项目根目录build.gradle内容：

修复建议 #

方案1：修改expo-firebase-core的Gradle配置（推荐） #

这个错误是因为Gradle 7.x中Jar任务的classifier属性已被archiveClassifier替代，而expo-firebase-core的旧版本仍在使用废弃属性。可以通过patch-package生成永久补丁：

1. 安装patch-package：

   npm install patch-package --save-dev
   

2. 打开node_modules/expo-firebase-core/android/build.gradle，找到androidSourcesJar任务：

   task androidSourcesJar(type: Jar) {
       classifier = 'sources'
       from android.sourceSets.main.java.srcDirs
   }
   

3. 将classifier = 'sources'替换为archiveClassifier = 'sources'：

   task androidSourcesJar(type: Jar) {
       archiveClassifier = 'sources'
       from android.sourceSets.main.java.srcDirs
   }
   

4. 生成补丁：

   npx patch-package expo-firebase-core
   

5. 重新执行构建：

   npm run build
   

方案2：调整expo-firebase-core版本 #

Expo 49推荐使用expo-firebase-core@~6.0.0，当前使用的^6.0.0可能拉取了不兼容的小版本。修改package.json中的版本：

"expo-firebase-core": "~6.0.0"

然后删除node_modules和package-lock.json，重新安装依赖：

rm -rf node_modules package-lock.json
npm install

方案3：清理项目缓存 #

执行以下命令清理Expo缓存和构建文件：

npx expo prebuild --clean
npm run build
