The short answer is: no

I've been running into the plugin when I tried to use the protobuf gradle plugin. It wraps protoc which it loads from maven central if I remember correctly. Or maybe it was a protoc plugin that was loaded separately from Maven Central.
Anyway, the issue with these things is that there's no unified way to point them to a directory for looking up natives. Some may have a system property, some may look at PATH, sometimes there's a Gradle plugin config...
So I wouldn't know how to solve this problem in a generic way.

I think what we would need is to be able to have drvs for all libs on maven central and then be able inject the build time dependencies on the nix level.
But thats a completely different and radical approach compared to the dependency FOD solution that we have right now.

has there been any work on the libre/binary-free bootstrap recently? Came across that discussion and at least to me doesn't seem like there's any movement on it

And if there isn't, would there be interest in me picking up that work? I've been looking at reducing nixpkgs' reliance on binary bootstraps in various places and openjdk/JDKs in general seem like a good place to do that for

Not really, at least to my knowledge.

I was the one who personally removed the previous bootstrap chain, because it was broken, unmaintained, and not even used.

If you want to look into it, be my guest, but you'll need to commit to maintaining it. I don't want to need to come back down the line and delete another bootstrap chain

I would personally love to see this, but I think it is not feasible at present. The limited bandwidth of current NixOS JVM contributors would be better spent elsewhere IMO.

If you are interested in using or contributing to a libre/binary-free JDK bootstrap, GUIX is the place. GUIX (last I checked) is lagging behind on Maven support (for example) so they could use help, too.
