当我使用 flutter 构建应用程序时，它会出现 Gradle 错误

Question

当我尝试使用 Android 在 Flutter 中构建应用程序时，出现错误。

我尝试过

flutter clean

，

flutter doctor

，删除构建文件夹，但没有任何效果。

我可以在 Windows 和 Web 中构建，但 Android 给我这个错误：

FAILURE: Build failed with an exception.

• 地点： 构建文件

  D:\Projectos\flutter\todo\todo3\todo_app\android\app\build.gradle

  行：2

• 出了什么问题：

    An exception occurred applying plugin request [id: 'com.android.application']
    Failed to apply plugin 'com.android.internal.application'.
    Android Gradle plugin requires Java 17 to run. You are currently using Java 11.
    Your current JDK is located in C:\Program Files\Android\Android Studio\jre
    You can try some of the following options:
    - changing the IDE settings.
    - changing the JAVA_HOME environment variable.
    - changing `org.gradle.java.home` in `gradle.properties`.

我的

build.grade

代码是：

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.todo_app"
    compileSdk = flutter.compileSdkVersion
    ndkVersion = flutter.ndkVersion

    compileOptions {
        sourceCompatibility = JavaVersion.VERSION_1_8
        targetCompatibility = JavaVersion.VERSION_1_8
    }

    kotlinOptions {
        jvmTarget = JavaVersion.VERSION_1_8
    }

    defaultConfig {
        // TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
        applicationId = "com.example.todo_app"
        // 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.debug
        }
    }
}

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

错误消息就在那里说明：

Android Gradle plugin requires Java 17 to run. You are currently using Java 11.

所以安装 Java 17。
