How to run a main application (not a spring boots appl) from a folder of Spring Boot application as jar

Question

Background: I have written a one-time tool to run as a non-spring boot application in one of the folder of Spring Boots. This tool calls a class from Spring boots application.

I tried : java -jar <jarName> <com.dummy.folder3.Mainpgm1> -u <username> -p <password>

This when calls spring boots class fails with "Invalid parameters; exiting without generation"

Folder structure:

com/
  dummy/
   <folder1>
   <folder2>
   <folder3>
      Mainpgm1
   Application

Any help
