Describe the problem you are trying to solve

I'm using steve for testing as a server for my OCPP.
but instead of the available parameters in Data transfer operation, I needed to add some other parameters.
for that, I'm unable to find the DataTransferRequest class java file.

...

Describe the solution you'd like

fetch where this DataTransferRequest class/file is located ?
and the functions associated with the parameters of that class.
...

I've tried making changes in .xml file but I'm not able access where the associated functions are being implemented.
...

Additional context

i need to where the functions like withMessageId(), withvendorId() are defined/implemented
...

you want to make changes to the source code, but you struggle with it. i assume that some fundamental java knowledge missing. github issues are not a platform for these kind of questions. i would suggest to google for learning material about modern java development, maven and spring framework.
