If you want to change Java code I would recommend just building JAR file and replacing it in existing Traccar instance.
replace tracker-server.jar ?
Yes. Make sure that you use corresponding tag as a base for your modifications.
ok thank you anton, I want try use Firebase Cloud Mesaging
Then it's not that easy. You need to update everything, including third party libraries.
yes Not easy, I has been finish build to jar with maven "assembly:single", but why file very big size, size I am build 41Mb and file tracker-server.jar only 1Mb ?
I would recommend you to wait for next official release, unless you absolutely know what you are doing.
Also, have you compiled mobile apps as well, if you want to try push notifications?
ok Anton I will wait release from you, yes I have compile for apk

It's not related to this topic, and you also need to search for a solution first before asking for help. If you don't do that, when you actually have a genuine problem, I won't be answering your questions anymore.
