When Maven settings.xml credentials are rejected by the remote repository (401/403), retry the JAR download without authentication. Mirrors `MavenPomDownloader.requestAsAuthenticatedOrAnonymous()` and Apache Maven's behavior, so anonymous-accessible artifacts resolve even when configured credentials are invalid. Also fixes two nits observed during troubleshooting: - local cache filename was missing the hyphen before the classifier (`foo-1.0.0recipes.jar` → `foo-1.0.0-recipes.jar`) - download error message omitted the classifier

Summary
MavenArtifactDownloadernow retries the JAR download anonymously whensettings.xmlcredentials are rejected by the remote repository (4xx), mirroringMavenPomDownloader.requestAsAuthenticatedOrAnonymous(). Credentials are applied first, so existing authenticated downloads against private repositories are unchanged and the anonymous attempt is only a fallback.Fix
LocalMavenArtifactCachecache filename missing the hyphen before the classifier (foo-1.0.0recipes.jar→foo-1.0.0-recipes.jar).Include the classifier in the
MavenDownloadingExceptionmessage so artifact coordinates are complete during troubleshooting.Split from the first commit of Try Maven downloads anonymously first, retry with credentials on 4xx #7447, to land this with minimal risk to existing behavior. A follow-up PR will mirror Apache Maven's anonymous-first behavior.
