it's definitely boot.core/sync-user-dirs! that's resetting the filesystem - I verified by calling it in my task, rather than waiting for the one called in run-tasks!. Digging into that today.

in an ironic twist of fate, I think that this problem is related to the fileset diffing change that I did

I don't have more to report yet, but this is looking like a more appropriate stream of consciousness for #boot-dev, so any further updates will be there, if you're following along

I wrote a guide on public maven repositories that you're likely to encounter on the JVM: https://www.deps.co/guides/public-maven-repositories/

@danielcompton FYI, in the past, http://build.clojure.org acted as a Maven repo. Early versions of clojure, clojure-contrib, and a few other things were released there before they started getting published to Maven Central. I killed that repo (accidentally) about a year ago when we upgraded the build box. Since then, I’ve had a few people run into projects that included that repository and were relying on very old artifacts from there. Many of the important jars were already also available on Maven Central but I did find some old clojure-contrib builds and a few odds and ends that were only in that old repo and published those as well. In the unlikely event that you ever hear of anyone running into this, I have a backup of the full repo just in case.
