Ask JitPack metadata last for names no other repo knows and that are not com.github.* (whose metadata is 401, tags used instead). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01WzxdWY1k4muZfdVJfb7YGJ

"""Maven repositories: newest stable of `group:artifact`, from maven-metadata.
|
|
|
|
Three repositories, ALL asked: Google Maven (every `androidx.*` and
|
|
`com.android.*` artifact lives ONLY there), Maven Central and the Gradle
|
|
plugin portal (plugin marker artifacts `<id>:<id>.gradle.plugin`). The
|
|
version lists are pooled and the newest stable across them wins. Stopping at
|
|
the first repository that knew the artifact graded
|
|
`com.github.ben-manes:gradle-versions-plugin` current at 0.51.0 because
|
|
Central still carries its 2016 releases (0.11.1) while the plugin portal has
|
|
0.54.0 (2026-09-18). A 404 means "not here", not "not anywhere"; anything
|
|
else surfaces as `Offline` from the HTTP layer.
|
|
|
|
JitPack used to be the fourth: it served tag metadata for `com.github.*`
|
|
artifacts published nowhere else (PhotoView, DirectionalViewPager). Since
|
|
2026-09 that endpoint answers HTTP 401 "No access token" while the artifacts
|
|
themselves still download, so a `com.github.<owner>:<repo>` name that no
|
|
repository knows is answered from the GitHub repo's tags over `git
|
|
ls-remote` (unmetered, no token). JitPack's version IS the tag name, `v`
|
|
prefix included, so the tags are compared as they are. Artifacts JitPack
|
|
hosts under their OWN group (`cz.adaptech.tesseract4android`) still get
|
|
200 metadata there, so JitPack is the last resort for any other name.
|
|
|
|
`<latest>` and `<release>` in the metadata are not trusted: AndroidX writes
|
|
`1.2.0-alpha03` into `<latest>` routinely. The full `<versions>` list goes
|
|
through `newest_stable` like every other ecosystem. Only when NO repository
|
|
has a stable release at all does the newest pre-release become the reference
|
|
(`versions.reference`), which is how `androidx.biometric:biometric-ktx`,
|
|
alpha-only since 2021, gets a checkable answer. Google's API clients
|
|
(`v3-rev20260901-2.0.0`) are neither: for those the answer is the newest
|
|
revision of every generation, and the judge picks the pin's own.
