gradle构建报错

```
An exception occurred applying plugin request [id: 'org.springframework.boot', version: '2.6.11']
> Failed to apply plugin [id 'org.springframework.boot']
> Spring Boot plugin requires Gradle 6.8.x, 6.9.x, or 7.x. The current version is Gradle 6.4.1
```

Start by inspecting the project's Gradle configuration and the org.springframework.boot plugin declaration, then reproduce the reported build with Gradle 6.4.1. Confirm the required Gradle and plugin versions and verify that the project builds successfully with compatible versions.
