Anserini Fatjar

Overview

Use this skill to install and run Anserini quickly by downloading the latest fatjar from Maven Central into the current working directory.

Validation note:

• Validated on 2026-03-27 against anserini-1.7.1-fatjar.jar
• Verified locally: fatjar download, cacm-download reproduction, catalog lookups, Search CLI, and RestServer

Workflow

1. Verify runtime tools.
2. Download the latest fatjar from Maven Central.
3. Run smoke test/help command.
4. Execute target commands.

For a reusable end-to-end check of the documented workflow, run:

SKILL_DIR="/path/to/anserini-fatjar"
bash "$SKILL_DIR/scripts/verify_fatjar_workflow.sh"

1. Verify Runtime Tools

Run:

java -version
javac -version
wget --version

Require:

• JDK 21 available on PATH for both java and javac
• wget available on PATH
• Optional: jq available on PATH for JSON filtering commands below

Stop immediately and warn the user if prerequisites are not satisfied. In particular:

• If java -version or javac -version does not report JDK 21, do not continue.
• If wget is missing, do not continue with Maven Central download steps.
• If jq is missing, continue only when JSON filtering is unnecessary or replace those examples with an equivalent plain-text inspection.

2. Download Latest Fatjar

From the skill directory, run:

SKILL_DIR="/path/to/anserini-fatjar"
bash "$SKILL_DIR/scripts/fetch_latest_fatjar.sh"

This script probes Maven Central metadata at https://repo1.maven.org/maven2/io/anserini/anserini/maven-metadata.xml, extracts the current release, and downloads anserini-<version>-fatjar.jar from the matching official artifact path. At the moment, a direct example URL is:

wget https://repo1.maven.org/maven2/io/anserini/anserini/1.7.1/anserini-1.7.1-fatjar.jar

All subsequent commands assume the jar is available in the current working directory as anserini-<version>-fatjar.jar. Resolve the filename dynamically before invoking Java:
