Flutter项目在Fedora系统VS Code中持续提示OpenJDK 21工具链不满足能力要求的问题求助

各位好，我最近在Fedora 41系统的VS Code里开发Flutter项目时，一直被一个顽固的Java工具链警告折腾，试了好几种方法都没解决，想来请教下大家的思路。

每次打开项目都会弹出这个错误：

The supplied phased action failed with an exception. Could not create task ':app:compileDebugAndroidTestJavaWithJavac'. Failed to calculate the value of task ':app:compileDebugAndroidTestJavaWithJavac' property 'javaCompiler'. Toolchain installation '/usr/lib/jvm/java-21-openjdk' does not provide the required capabilities: [JAVA_COMPILER]

奇怪的是，我明明已经把Java版本切换到OpenJDK 24了，但警告还是死死盯着OpenJDK 21不放，这到底是哪里还没改到位？

我已经尝试过的操作 #

• 修改了系统的JAVA_HOME环境变量，指向OpenJDK 24的安装目录
• 执行Flutter命令指定JDK路径：flutter config --jdk-dir="/usr/lib/jvm/java-24-openjdk/"
• 在项目的android/gradle.properties文件里添加了org.gradle.java.home=/usr/lib/jvm/java-24-openjdk

相关配置输出 #

以下是flutter doctor --verbose的结果：

项目中android/app/build.gradle.kts的配置（已省略项目名称）：

plugins {
    id("com.android.application")
    id("kotlin-android")
    // The Flutter Gradle Plugin must be applied after the Android and Kotlin Gradle plugins.
    id("dev.flutter.flutter-gradle-plugin")
}

android {
    namespace = "com.example.x"
    compileSdk = flutter.compileSdkVersion
    ndkVersion = flutter.ndkVersion

    compileOptions {
        sourceCompatibility = JavaVersion.VERSION_11
        targetCompatibility = JavaVersion.VERSION_11
    }

    kotlinOptions {
        jvmTarget = JavaVersion.VERSION_11.toString()
    }

    defaultConfig {
        // TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
        applicationId = "com.example.x"
        // You can update the following values to match your application needs.
        // For more information, see: https://flutter.dev/to/review-gradle-config.
        minSdk = flutter.minSdkVersion
        targetSdk = flutter.targetSdkVersion
        versionCode = flutter.versionCode
        versionName = flutter.versionName
    }

    buildTypes {
        release {
            // TODO: Add your own signing config for the release build.
            // Signing with the debug keys for now, so `flutter run --release` works.
            signingConfig = signingConfigs.getByName("debug")
        }
    }
}

flutter {
    source = "../.."
}

我现在有点摸不着头脑了，明明已经切换了JDK，但系统还是揪着OpenJDK 21不放，而且flutter doctor显示的Java版本是17，Android Studio里又是21，这几个版本之间会不会有冲突？有没有大佬知道哪里可能还有隐藏的配置没改到？
