Springboot部署宝塔错误，提示找不到org.springframework.boot.SpringApplication类

Question

把Springtboot在宝塔上部署的时候提示问题

Exception in thread "main" java.lang.ClassNotFoundException: classes.com.example.demo.DemoApplication
    at java.net.URLClassLoader.findClass(URLClassLoader.java:381)
    at java.lang.ClassLoader.loadClass(ClassLoader.java:424)

但是在IDEA上面运行DemoApplication是没有问题的

但是在打包jar出来后，在本地java -jar就提示

Exception in thread "main" java.lang.reflect.InvocationTargetException
        at java.base/jdk.internal.reflect.DirectMethodHandleAccessor.invoke(DirectMethodHandleAccessor.java:119)

我的MANIFEST.MF:

Manifest-Version: 1.0
Spring-Boot-Classpath-Index: BOOT-INF/classpath.idx
Implementation-Title: demo
Implementation-Version: 0.0.1-SNAPSHOT
Spring-Boot-Layers-Index: BOOT-INF/layers.idx
Start-Class: com.example.demo.DemoApplication
Spring-Boot-Classes: BOOT-INF/classes/
Spring-Boot-Lib: BOOT-INF/lib/
Build-Jdk-Spec: 1.8
Spring-Boot-Version: 2.6.0
Created-By: Maven JAR Plugin 3.2.2
Main-Class: org.springframework.boot.loader.JarLauncher

DemoApplication确实存在于解压后的\XTool\BOOT-INF\classes\com\example\demo里面，但是为什么会提示找不到呢？

先把 spring-boot-maven-plugin 中的 configuration、executions 去掉再 package 就可以了
