Maven Central

Mode: 🌐 Public · Domain: search.maven.org

Search Maven Central artifacts and pull per-artifact version histories without auth or browser. Two commands.

Commands

Command	Description
opencli maven search <query>	Search Maven Central by keyword (artifact name, groupId, tag)
opencli maven artifact <coordinate>	Version history for groupId:artifactId[:version]

Usage Examples

# Free-text search
opencli maven search jackson --limit 10
opencli maven search "ai.koog" --limit 5

# Version history for a specific artifact (use `coordinate` from search rows)
opencli maven artifact com.fasterxml.jackson.core:jackson-databind --limit 10
opencli maven artifact com.google.guava:guava --limit 5

# Pin to a specific version
opencli maven artifact com.google.guava:guava:33.0.0-jre

# JSON output
opencli maven search jackson -f json

Output Columns

Command	Columns
search	rank, coordinate, groupId, artifactId, latestVersion, packaging, versions, lastPublished, repository, url
artifact	groupId, artifactId, version, packaging, publishedAt, tags, url

The coordinate column from search round-trips into artifact exactly. To pin a single version, append :<version>.

Options

maven search

Option	Description
query (positional)	Free-text query
--limit	Max artifacts (1-200, default: 30)

maven artifact

Option	Description
coordinate (positional)	groupId:artifactId or groupId:artifactId:version
--limit	Max versions (1-200, default: 20). Ignored when version is pinned.

Caveats

• Coordinates are validated upfront — groupId and artifactId must be [A-Za-z0-9][A-Za-z0-9._-]* (max 200 chars each). Bad input raises ArgumentError.
• lastPublished / publishedAt are derived from Solr's epoch-ms timestamp and rendered as second-precision YYYY-MM-DDTHH:MM:SSZ.
• Maven Central throttles bursts; HTTP 429 surfaces as a typed CommandExecutionError with a retry hint.
• versions (in search) is the count Solr reports — it includes pre-releases as well as stable versions.

Prerequisites

• No browser required — uses search.maven.org/solrsearch/select (Solr endpoint).
