报错截图：
二、解决
2.1 以管理员身份运行IDEA
2.2 检查对应的Dockfile文件的配置
检查ruoyi-nacos.jar相关内容是否配置有误：
2.3 maven操作
双击clean:
双击package:
already in use by container：
删除nacos containers改用docker compose 方式启动：
nacos运行报错-jar: file does not exist&Can’t retrieve image ID from build stream 问题解决了。
这里又会报一个常见的错误： No DataSource set
nacos: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'memoryMonitor' defined in URL [jar:file:/ruoyi/nacos/app.jar!/BOOT-INF/lib/nacos-config-2.2.1.jar!/com/alibaba/nacos/config/server/monitor/MemoryMonitor.class]: Unsatisfied dependency expressed through constructor parameter 0; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'asyncNotifyService': Unsatisfied dependency expressed through field 'dumpService'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'externalDumpService': Invocation of init method failed; nested exception is ErrCode:500, ErrMsg:Nacos Server did not start because dumpservice bean construction failure :
