Hi , You done modifications ,thats fine. Do you want to reflect these changes in ODL or in your toaster itself? are you launching your toaster karaf/ or ODL karaf to check the changes? I guess you could see this changes in your Toaster application only.Bec In ODl, toaster project is located at diff location like sample project/ .. But I believe here you are creating your toaster.
ok , After modifications in your toaster, build it , It will be updated in m2/repository automatically. You dont need to do anything externally . To confirm it , Use some logger_info or SOP in your code. More over You can run debug mode also.So that you could see the runtime value where you have modified.
Enable debug mode in your IDE , and launch karaf with debug command.
Hope It might helped!
Thanks,
