exe4j 打包 spring-boot 应用 报错

Question

java.lang.NoClassDefFoundError: BOOT-INF/classes/com/example/DemoApplication (wrong name: com/example/DemoApplication)

        at com.exe4j.runtime.WinLauncher.main(WinLauncher.java:101)

这只是一个 demo

DemoApplication.java

package com.example;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class DemoApplication {

    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
    }
}

是 用 exe4j 打包的步骤出现问题了 还是 本身这个程序就不能 用 exe4j 打包吗
