New Jira Server Developer

Dear Developer Team,

I am a new developer and want to design and developer plugins for Jira server. I am using jira sdk, java and eclipse but facing challenges. I have been following jira document but sometime get lost, as the guide sometime directs to jira forge.
Can someone please recommend me a book or something which can help me?

Thank you.

Best Regards
