Mac端Android Studio中Flutter项目JAVA_HOME配置异常求助

初始错误触发场景 #

更新Java时误重置项目JAVA_HOME路径，导致应用构建时报错：

ERROR: JAVA_HOME is set to an invalid directory: Users/{My UserName}/Library/Java/JavaVirtualMachines/openjdk-23.0.1

Please set the JAVA_HOME variable in your environment to match the
location of your Java installation.

本地Java环境排查 #

执行终端命令查找已安装Java版本及路径：

/usr/libexec/java_home -V

返回结果：

Matching Java Virtual Machines (1):
    1.7.45.18 (x86_64) "Oracle Corporation" - "Java" /Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home
/Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home

环境变量配置尝试 #

编辑.zshrc文件添加以下配置：

export JAVA_HOME=$(/usr/libexec/java_home -v 1.7.45.18)

export PATH=$JAVA_HOME/bin:$PATH

执行echo $JAVA_HOME确认路径已生效：

/Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home

但重新构建应用时仍弹出相同的JAVA_HOME无效错误。

临时环境变量设置失败 #

在项目目录终端执行临时设置命令：

export JAVA_HOME=“/Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home”

得到错误提示：

export: not valid in this context: /Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home

Android Studio端排查补充 #

通过File > Project Structure...下载新JDK，并更新.zshrc中的JAVA_HOME为新JDK路径，但执行flutter run仍报错：

ERROR: JAVA_HOME is set to an invalid directory: Users/{MyName}/Library/Java/JavaVirtualMachines/openjdk-23.0.1

Please set the JAVA_HOME variable in your environment to match the
location of your Java installation.

执行flutter doctor -v检测到：

Java binary at: Users/{MyName}/Library/Java/JavaVirtualMachines/openjdk-23.0.1/bin/java
    ✗ Cannot execute Users/{MyName}/Library/Java/JavaVirtualMachines/openjdk-23.0.1/bin/java to determine the version

执行flutter analyze --suggestions返回：

[✗] Java/Gradle/Android Gradle Plugin:
 Incompatible Java/Gradle versions.
 Java Version: null, Gradle Version: 7.6.3

当前echo $JAVA_HOME输出路径与Android Studio项目结构中配置的路径一致，但Java版本显示为null，问题仍未解决。
