Cache archive artifacts from Maven repositories - #425
Merged
Merged
Conversation
The Maven handler cached only .jar, .war, .ear, .pom, .aar, .klib and
.module files, so distributions published as archives, such as
apache-maven-{version}-bin.tar.gz, were proxied uncached on every request.
.zip, .tar.gz, .tgz, .tar.bz2 and .tar.xz files now go through the artifact
cache like other artifacts.

The added archive extensions use the existing artifact cache and Gradle Plugin Portal fallback. Checksums and signatures retain their metadata handling.

The Maven handler caches only
.jar,.war,.ear,.pom,.aar,.kliband.modulefiles. Everything else goes toproxyUpstream, uncached, so distributions published as archives on Maven Central, such asorg/apache/maven/apache-maven/3.9.9/apache-maven-3.9.9-bin.tar.gz, are fetched from upstream on every request.This adds
.zip,.tar.gz,.tgz,.tar.bz2and.tar.xzto the artifact extensions. They take the same path as jars, including the Gradle Plugin Portal fallback, and are listed under theirgroup:artifactname. Checksums and signatures (.tar.gz.sha512etc.) still matchisMetadataFilefirst, so they're unchanged.Tested with
go test ./...andgolangci-lint run ./...(v2.13.1, 0 issues), and by running the proxy against Maven Central: the first fetch ofapache-maven-3.9.9-bin.tar.gztook 1.7s, the second 16ms from cache, and/api/search?ecosystem=mavenlistsorg.apache.maven:apache-maven.
