当我尝试运行应用程序时，我得到：

Error: Could not find or load main class com.example.springboot.JgsbrmqApplication
Caused by: java.lang.ClassNotFoundException: com.example.springboot.JgsbrmqApplication

字符串
主要类别：

package com.example.springboot;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class JgsbrmqApplication {
    public static void main(String[] args) {
        SpringApplication.run(JgsbrmqApplication.class, args);
    }
}

我已经尝试了所有方法：重新加载项目，mvn clean install（这会给出一个错误，与Java 17有关）：

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.11.0:compile (default-compile) on project jgsbrmq: Fatal error compiling: error: release version 17 not supporte
