Flutter检测提示Java版本过低但已配置高版本JDK问题咨询

已正确配置JAVA_HOME环境变量，系统安装Java 19版本，但执行flutter doctor时发现Android工具链使用的是Android Studio内置的OpenJDK 11；运行flutter doctor --android-licenses时提示需要Java 17或更高版本，怀疑是Flutter SDK版本过旧，附上相关命令执行结果及配置截图寻求解决方案。

5. 相关配置截图 #

• 环境变量配置截图

解决方案 #

1. 指定Flutter使用系统Java 19 #

Flutter默认优先调用Android Studio内置JDK，可通过环境变量强制指定系统Java：

• 打开系统环境变量，新增ANDROID_STUDIO_JDK变量，值设为Java 19的安装路径（如C:\Program Files\Java\jdk-19）
• 重启命令行窗口，重新执行flutter doctor和flutter doctor --android-licenses

2. 更新Android Studio至新版本 #

当前Android Studio 2021.3内置JDK 11，升级到Hedgehog（2023.1.1）及以上版本后，内置JDK会更新到17，满足许可证验证的版本要求：

• 打开Android Studio，通过帮助 > 检查更新完成版本升级
• 重启软件后重新执行相关命令验证

3. 临时跳过JDK版本检查（不推荐长期使用） #

若需快速完成许可证验证，可执行以下命令临时绕过版本检查：

set SKIP_JDK_VERSION_CHECK=true && flutter doctor --android-licenses

此方案仅为临时应急，长期使用可能引发其他兼容性问题。

4. 升级Flutter SDK至最新稳定版 #

Flutter 3.24.3本身支持Java 17+，但结合Android SDK 35.0.0，升级到最新稳定版可避免潜在的版本兼容问题：

flutter upgrade
