I'm starting a development with Jive. I have to learn how to write plugin, use REST api etc, but we don't have Jive license yet - it takes a time while the company organizes it (contract, budget etc. - you know). But I'd like to prepare me and it isn't enough to read documentation. I found on the website how to gain a trail license to the online system, but I don't think it's a best way to playing with codes. Can you help me, is there any solution to build a Jive sandbox locally without working license?
