升级Android Studio Electric Eel后React Native项目JAVA_HOME报错求助

我正在开发React Native+TypeScript移动应用，升级Android Studio后项目构建失败，折腾数小时仍无法解决持续出现的JAVA_HOME错误。

已安装的Android Studio信息 #

Android Studio Electric Eel | 2022.1.1

当前环境配置 #

• 当前JAVA_HOME设置为C:\Program Files\Java\jdk-19
• 可选有效路径：C:\Program Files\Android\Android Studio\jbr（该路径下包含\bin\java.exe）

构建错误信息 #

执行react-native run-android时触发错误：

解决步骤 #

1. 更新JAVA_HOME环境变量 #

Android Studio Electric Eel及后续版本自带的JDK目录为jbr，而非旧版的jre，Gradle仍在查找旧路径导致错误。修改环境变量：

• 打开系统环境变量设置（右键此电脑→属性→高级系统设置→环境变量）
• 找到JAVA_HOME变量，将值改为C:\Program Files\Android\Android Studio\jbr
• 检查Path变量，确保已添加%JAVA_HOME%\bin

2. 验证配置有效性 #

打开新的命令提示符或PowerShell，执行以下命令：

echo %JAVA_HOME%
java -version

确认输出路径为C:\Program Files\Android\Android Studio\jbr，且能正常显示Java版本信息。

3. 清理Gradle缓存并重构 #

进入项目的android子目录，执行：

gradlew clean

返回项目根目录，重新运行构建命令：

react-native run-android

4. 强制Gradle指定JDK（可选） #

若环境变量修改后问题仍存在，在项目的android/gradle.properties文件中添加以下配置：

org.gradle.java.home=C:\\Program Files\\Android\\Android Studio\\jbr
