Bundle com.twelvemonkeys.imageio.bmp does not exist in the workspace or the current target platform

I'm trying to get Eclipse setup so I can build; I believe I've followed all the instructions at https://github.com/portfolio-performance/portfolio/blob/master/CONTRIBUTING.md, but a single error remains: Bundle com.twelvemonkeys.imageio.bmp does not exist in the workspace or the current target platform. I'm not at all familiar with Eclipse, but I just took a guess & tried to search for "Twelvemonkeys" under Help->Eclipse Marketplace, & installed the only thing that came up (Quickimage2), but it didn't resolve.

Is something missing in the setup instructions, or did I just miss something? I searched both Github Issues & the forum for "twelvemonkeys" but got no hits. I've reloaded the target platform.

Hello @metal450
Have you installed the M2E packages?

[metal450]

Yup, installed.

So I dumped everything & started completely over from scratch, and somehow this time that error is gone, but there are different ones:

However, PP does seem to be able to build & run, so I guess good enough.

(Man though, I've worked with a lot of IDEs in my day, but I gotta say...never seen anything that felt even close to as clunky/unintuitive as Eclipse. 😵‍)
