Flutter启动模拟器应用报错：无法找到有效javaHome路径

问题概述 #

Flutter搭配Android Studio Electric Eel开发，时隔一月后在VS Code启动初始应用时，Gradle构建失败，提示指定的JavaHome路径无效，系统识别的路径为C:\Program Files\Java\jre-10.0.2\bin\java.exe，但Android Studio实际安装在Z:\Program Files\Android\Android Studio。

报错信息 #

PS E:\projects\first_app> flutter run
Using hardware rendering with device sdk gphone x86 64. If you notice graphics artifacts, consider enabling software rendering with "--enable-software-rendering".

无效尝试 #

• 手动将C:\Program Files\Java\jdk-19内容复制到JRE文件夹，虽能临时解决构建问题，但会覆盖其他应用依赖的JRE，存在兼容性风险
• 新增或修改系统环境变量JAVA_HOME指向正确JDK路径，无效果

有效解决步骤 #

1. 使用Revo卸载工具彻底清理系统中所有Java版本（包括各类JDK、JRE）
2. 重新安装Java 8版本
3. 重新执行flutter run命令，应用可正常在模拟器启动
