JOSM project deployment in PT_Assistant plugin

[Vaibhav Bisht]

Hii,
Vaibhav here, I have compiled the PT_Assistant plugin with Gradle but most
of the classes are extending from JOSM so my question is?

where can I find the JOSM source code inside the PT_Assistant plugin?

Is there any source code of JOSM inside the plugin or is there any .jar
file for JOSM inside PT_Assistant plugin. Please let me know where can I
find it inside my PT_Assistant plugin.
And also how would I update the JOSM code.
By the way, I already have the JOSM source code but I would like to know
where can I find it inside my PT_Assistant.
Thank you
Truly yours
Vaibhav
