Flutter报错Your project's Gradle version is incompatible with the Java version that Flutter is using for Gradle.

不想多说什么，各种傻逼环境搞得人想吐，Gradle + Java 屎中屎，尤其是出现版本不兼容的情况时！

## 解决办法

有好多个Java环境、Gradle环境、Android环境、Flutter环境相关的配置细节，不想深究这傻逼玩意，全部列出来，依次排查解决吧，最终使用统一环境基本就可以了~

> 下面的示例是在 `Java17` 情况下的正常运行配置，如果你使用 Java17，按照示例配置即可。（不保证完全正确！）

### gradle.properties

- `android/gradle.properties` Java版本

注意其中的 `java.home`
```env
org.gradle.jvmargs=-Xmx4G -XX:MaxMetaspaceSize=2G -XX:+HeapDumpOnOutOfMemoryError
android.useAndroidX=true
android.enableJetifier=true
org.gradle.java.home=C:\\Program Files\\Java\\jdk-17
```

### setting.gradle

- `android/setting.gradle` Android - Gradle 工具包版本

注意其中的 `com.android.application`，不过这个错误好解决，可以放在最后！

当其他环境配置统一后，最后保证这里版本可用就没问题了。
```json
pluginManagement {
    def flutterSdkPath = {
        def properties = new Properties()
        file("local.properties").withInputStream { properties.load(it) }
        def flutterSdkPath = properties.getProperty("flutter.sdk")
        assert flutterSdkPath != null, "flutter.sdk not set in local.properties"
        return flutterSdkPath
    }()

    includeBuild("$flutterSdkPath/packages/flutter_tools/gradle")

    repositories {
        google()
        mavenCentral()
        gradlePluginPortal()
    }
}

plugins {
    id "dev.flutter.flutter-plugin-loader" version "1.0.0"
    id "com.android.application" version "8.1.0" apply false
    id "org.jetbrains.kotlin.android" version "1.8.22" apply false
}

include ":app"

```

### gradle-wrapper.properties

- `android/gradle/wrapper/gradle-wrapper.properties` Gradle版本

注意其中 `distributionUrl` ，配置与Java版本相匹配的 Gradle版本，请自行确定版本号。

```
distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists
distributionUrl=https\://services.gradle.org/distributions/gradle-8.0-all.zip

```

### Flutter配置JDK版本

使用命令 `flutter doctor --verbose` 检查当前配置的JAVA版本！

可以看到一部分配置信息如下：
```log
[√] Android toolchain - develop for Android devices (Android SDK version 35.0.0) [2.0s]
    • Android SDK at E:\dependencies\android\
    • Platform android-35, build-tools 35.0.0
    • Java binary at: C:\Program Files\Java\jdk-17\bin\java
      This JDK is specified in your Flutter configuration.
      To change the current JDK, run: `flutter config --jdk-dir="path/to/jdk"`.
    • Java version Java(TM) SE Runtime Environment (build 17.0.14+8-LTS-191)
    • All Android licenses accepted.
```

如果想要修改Java版本，可以通过如下命令修改（请自行修改目录）：

```sh
flutter config --jdk-dir="C:\Program Files\java\jdk-17"
```

### 总结

大概配置点就是上面的这些，总之就是：保证 `Android` + `Gradle` + `Java` 环境能够保持通用，同时，要保证 `Flutter` 中配置的 `Java` 版本与项目中的配置一致！
