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：

    <dependency>
            <groupId>com.baomidou</groupId>
            <artifactId>mybatis-plus-spring-boot3-starter</artifactId>
            <version>3.5.6</version>
            <exclusions>
                <!-- 排除旧版本的扩展模块 -->
                <exclusion>
                    <groupId>com.baomidou</groupId>
                    <artifactId>mybatis-plus-extension</artifactId>
                </exclusion>
            </exclusions>
        </dependency>
        <!-- 手动引入统一版本的扩展模块 -->
        <dependency>
            <groupId>com.baomidou</groupId>
            <artifactId>mybatis-plus-extension</artifactId>
            <version>3.5.6</version>
        </dependency>

统一版本即可。
