desktop-release.yml

name: Desktop release

# A desktop-only preview release: the assets are files on a GitHub Release, nothing is published to
# Maven Central. Triggered by pushing a version tag (the coordinator tags after release -> main), or
# by hand for an existing tag. The assets are assembled by .github/scripts/release/assemble-desktop-release.sh,
# and both examples of docs/release/desktop run against those assets before anything is uploaded.
