Nothing in the desktop app needs the JBR anymore, so go back to OpenJDK
(Temurin 21) everywhere:
- Remove the JETBRAINS vendor pin from the desktop toolchain and from the
launcher that jpackage bundles as the app runtime
- Replace the setup-jbr composite action with actions/setup-java; the
retry logic only existed to survive rate limits on the jetbrains
distribution's release listing
- Swap the JBR SDK tarball for Temurin 21 in the snap and flatpak builds,
and verify the snap download's checksum
- Standardize the remaining 'adopt' setup-java steps on 'temurin'
Replace ad-hoc icon scripts with a single source-of-truth manifest
(scripts/assets.yaml) and a Python generator that renders every app icon,
store-listing graphic, MSIX tile, favicon, and the Play feature graphic from
two SVG sources. Compositions (icon + "Hammer" wordmark in Kingthings
Trypewriter) are defined once as percentages of canvas and reused across the
Play feature graphic, MSIX wide/splash tiles, and the Snap featured banner.
Adds the missing snap store icon, fixes the snap desktop icon to the correct
256x256 hicolor size, and routes uploads-only assets to build/store-assets/
(gitignored).
See docs/ASSET-GENERATION.md for the manifest schema.
Reverts the Nucleus packaging port and its follow-ups:
- 93c7973c Trying nucleus for packaging Snap stays bespoke
- 7c14bcd5 Broaden artifact staging to handle Nucleus sandboxed pipeline paths
- d24f6183 Add homepage and debMaintainer for electron-builder
- 8831e9c5 Update release workflows for Nucleus packaging
- 4af31163 Port :desktop packaging to Nucleus framework
Compose Desktop is back as the packaging backend (jpackage targets,
custom packageMsix task, bespoke buildDistSnap/AppImage/Flatpak via
registerLinuxDistributionTasks). The Nucleus runtime libraries —
nucleus.darkmode-detector and nucleus.decorated-window-jbr — are
kept for window decoration and dark-mode detection in code, along
with the JBR jvmToolchain vendor pin and the libs.versions.toml
'nucleus' version entry that they depend on.
The Nucleus-pipeline state is preserved on branch
'nucleus-build-pipeline' for future reference.
