Rookie programmer has some questions about new year

[sau]

Hi, I am the lead programmer of a team that lost almost all of its programmers and programming mentors, so we have almost no experience with frc programming. I know some basic java, but don't know too much, especially robot programming.

I have some questions about the new year:
1. I am aware that we are changing to Eclipse this year. Does anybody know why this change is taking place, and what we have to do to get the plugins. I have never used Eclipse before.

2.Where and when do we get the new FRC java API library? I heard somewhere that they were considering scrapping it and building a new one from scratch, is that true?

3. Lastly, where are some good places to learn and teach both basic java and robot programming, like autonomous, smart dashboard, ir sensors, and more that I can't think of. I'm expecting a number of people to join with little to no java experience, and I myself am not good at robot programming.
Is it all in the API library, or do I have to learn from somewhere else.

These are all the questions that I can think of now, I may add on to this post later if I have any more.

Thanks in advance for your help!
