jamesward / zio-mavencentral   0.8.0

A ZIO 2 / Scala 3 toolkit for working with Maven Central:

• Read API (MavenCentral) — typed GroupId / ArtifactId / Version / GroupArtifact[Version] coordinates, searchArtifacts, searchVersions, latest / latestOrFail, pom, mavenMetadata, isArtifact, artifactExists, isModifiedSince, and jarUri / javadocUri / sourcesUri URL resolution. Requests fall back from repo1.maven.org to repo.maven.apache.org and can opt in to retry-on-5xx via the retryOnServerError extension.
• Downloads — stream a jar to a File with downloadJar, or download-and-extract a zip with downloadAndExtractZip, both surfacing Last-Modified / ETag cache metadata.
• JarCache — scoped, on-disk jar cache with random-access ZipFile reads, single-flight deduplication of concurrent fetches for the same GAV, and finalizer-driven handle cleanup; entry lookups don't decompress the rest of the jar.
• GavCacheMiddleware — zio-http HandlerAspects that stamp GAV-versioned routes with a path-derived stable ETag, pinned Last-Modified, and Cache-Control: public, max-age, immutable, and short-circuit conditional GETs to 304 Not Modified before the upstream fetch.
• Path codecs (MavenCentral.Codecs) — zio-http PathCodecs for GAV value types.
• Publishing (MavenCentral.Deploy.Sonatype) — Sonatype Central Portal client: bundle upload, checkStatus, drop, and an end-to-end uploadVerifyAndPublish that polls until the deployment is VALIDATED then publishes. Sonatype.Live reads OSS_DEPLOY_USERNAME / OSS_DEPLOY_PASSWORD; Sonatype.fromCredentials accepts explicit values.
