gradle - 即使我似乎安装了正确的版本，也遇到了Gradle版本错误

Question

运行Gradle构建时出现此错误:

$ ./gradlew clean build

FAILURE: Build failed with an exception.

* Where:
Build file '/Users/paulcarron/Documents/Documents/Books/Learning Spring Boot 2/learning-spring-boot-2/build.gradle' line: 2

* What went wrong:
An exception occurred applying plugin request [id: 'org.springframework.boot', version: '2.3.1.RELEASE']
> Failed to apply plugin [id 'org.springframework.boot']
   > Spring Boot plugin requires Gradle 5 (5.6.x only) or Gradle 6 (6.3 or later). The current version is Gradle 6.0.1

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

我已经安装了Gradne 6.5:

$ gradle -v

这可能是什么问题？

只是为了细化评论中的正确答案。
程序gradle(如果有)将调用系统上安装的Gradle。可能是从您的PATH变量中找到的。gradlew脚本(注意'w')是通常添加到Git存储库中的包装器脚本。它调用Gradle的声明版本，并在必要时自动自动下载。它使用自己的安装文件夹(默认情况下为~/.gradle/wrapper，版本在[repo]/gradle/wrapper/gradle-wrapper.properties中声明)。
虽然可以手动更改版本，但最好运行./gradle wrapper --gradle-version 6.5 --distribution-type all，因为这也会在需要时更新包装器脚本本身。
