java Spring引导部署NoClassDefFoundError

Question

我正在尝试部署Spring Boot应用程序。我通过maven插件构建了一个jar文件。但我有一个错误是：

Exception in thread "main" java.lang.NoClassDefFoundError: org/springframework/boot/SpringApplication
        at com.spring-boot.example.AppConfig.main(AppConfig.java:18)
Caused by: java.lang.ClassNotFoundException: org.springframework.boot.SpringApplication
    at java.net.URLClassLoader.findClass(URLClassLoader.java:381)
    at java.lang.ClassLoader.loadClass(ClassLoader.java:424)
    at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:331)
    at java.lang.ClassLoader.loadClass(ClassLoader.java:357)
    ... 1 more

我试着给pom添加额外的插件。xml文件，但都不起作用。任何帮助都将不胜感激

这是我的pom。xml文件：
