Process finished with exit code 1

问题分析：

错误是由于 MyBatis-Plus 的 mybatis-plus-extension 模块版本与 mybatis-plus-core版本不一致，导致 ReflectionKit.getSuperClassGenericType 方法签名不兼容。Spring Boot 3.x 需要 MyBatis-Plus 3.5.3+ 版本，且所有相关模块必须版本统一。

成功解决：

    
            com.baomidou
            mybatis-plus-spring-boot3-starter
            3.5.6
            
                
                
                    com.baomidou
                    mybatis-plus-extension
                
            
        
        
        
            com.baomidou
            mybatis-plus-extension
            3.5.6
        

统一版本即可。
