添加google_sign_in依赖后Flutter应用构建失败求助

问题描述 #

在Flutter项目中集成Firebase谷歌登录时，只要添加google_sign_in依赖，应用就无法构建运行；移除该依赖则恢复正常，即使在新项目中也会出现相同问题，且无论是否连接Firebase都会构建失败。

已尝试操作 #

• 多次执行flutter clean、flutter pub get清理缓存并重建项目
• 安装并切换JDK 17、20、21版本，问题仍未解决

解决方案 #

1. 统一子项目Java版本配置 #

修改android/build.gradle，在subprojects块中添加编译配置，确保google_sign_in_android模块使用Java 17而非默认的Java 8：

subprojects {
    project.evaluationDependsOn(":app")
    // 新增以下配置
    tasks.withType(JavaCompile) {
        sourceCompatibility = JavaVersion.VERSION_17
        targetCompatibility = JavaVersion.VERSION_17
    }
    compileOptions {
        sourceCompatibility = JavaVersion.VERSION_17
        targetCompatibility = JavaVersion.VERSION_17
    }
}

2. 指定Gradle使用的JDK路径 #

在项目根目录的gradle.properties文件（无则创建）中添加JDK 17的安装路径，确保Gradle使用指定JDK而非Android Studio自带的JBR：

org.gradle.java.home=C:\\Program Files\\Java\\jdk-17.0.10

注意：替换为你实际的JDK 17安装路径，Windows系统路径需用双反斜杠

3. 更新Gradle版本 #

检查android/gradle/wrapper/gradle-wrapper.properties中的Gradle版本，设置为与Flutter 3.24.4兼容的版本（如8.7）：

distributionUrl=https\://services.gradle.org/distributions/gradle-8.7-all.zip

4. 彻底清理并重新构建 #

执行以下命令完成清理和重建：

flutter clean
flutter pub get
cd android
./gradlew clean
cd ..
flutter run

5. 修复Android SDK平台文件 #

• 打开Android Studio的SDK Manager，找到Android 14 (API 34)，卸载后重新安装完整的SDK Platform
• 若仍有问题，手动删除C:\Users\huzai\AppData\Local\Android\sdk\platforms\android-34目录，再重新安装API 34平台
