运行：mvn spotless:check，报错

问题：

在项目目录下运行：mvn spotless:check，报错：
[ERROR] Failed to execute goal com.diffplug.spotless:spotless-maven-plugin:2.43.0:check (default-cli) on project marionette: Execution default-cli of goal com.diffplug.spotless:spotless-maven-plugin:2.43.0:check failed: Unable to load the mojo 'check' in the plugin 'com.diffplug.spotless:spotless-maven-plugin:2.43.0' due to an API incompatibility: org.codehaus.plexus.component.repository.exception.ComponentLookupException: com/diffplug/spotless/maven/SpotlessCheckMojo has been compiled by a more recent version of the Java Runtime (class file version 55.0), this version of the Java Runtime only recognizes class file versions up to 52.0

错误原因：

Spotless 插件版本 2.43.0 是用 Java 11（class file version 55.0）编译的
但当前系统路径安装的 Java 版本是 Java 8（class file version 52.0）【本地运行：java -version，输出：java version "1.8.0_261"】，无法加载 Java 11 编译的类
项目选择的Java 版本是Java 11

解决：

直接双击Maven工具栏中的：Maven->项目名->plugins->spotless->spotless:check、Maven->项目名->plugins->spotless->spotless:apply，因为项目选择的java版本是Java 11，在项目里可以直接使用。
