This is almost certainly in the negative column for me. SBT has the dubious distinction of being the only build system that takes me hours to figure out how to change a setting. Inevitably I have to fall back to reading the source, and given all the macro magic that can be difficult to unwind.

I've been using Pants, mostly because it's polyglot and has better multi-project support. The oss community is a lot smaller, and it has a fair number of problems around bugs, but I find the code much more approachable.

where are you using Pants?

I would really love to be able to use Pants as well, but alas, once I got running on SBT and was faced with a bit of rough-edges in Pants public-facing adoption/documentation story, I had to abort :)

My current startup and my last one, both smaller orgs. I setup both build systems, and initially used SBT in the previous one. In both cases I think it helps that we had engineers from larger companies familiar with a working monorepo; if you've seen one done well you have some aspiration as to what to shoot for with pants, even if it's more than what's currently available.

I'd use SBT again for a locally contained, single project setup. Once you learn the arcana, it works well, has a ton of plugins, and the repl is nice. I don't think it scales well with new engineers or number of projects though.

All very reasonable, thanks.

I've used Blaze at Google and then Pants at Foursquare, so I've seen this sort of thing done, but yea, Pants seemed like it was going to take a higher level of commitment to set up / maintain, due to smaller OSS ecosystem around it, so I had to short-circuit that thread.

Also, putting everything in a monorepo is not really an option in my current OSS-focused setup, and I've come to have grave doubts about its desirability overall, after years of believing that it was the ideal way, but that's another discussion :)
