Dependency Watch

Script to wait for an artifact to appear on Maven Central or to monitor coordinates for new versions.

Just release a new artifact and want to know when you can start using it?

$ dependency-watch await com.example:example:1.1.0 && say "Example 1.1.0 is available!"

Pipe to a notification, email, HTTP request, sound, or anything else your heart desires.

Monitor

The notify subcommand allows you to monitor multiple groupId/artifactId coordinates at once.

Create a config.yaml with a coordinate list.

coordinates:
 - com.example:example
 - com.jakewharton:dependency-watch

Pass the config file and a --data directory to store already-seen versions:

$ dependency-watch notify --data data config.yaml

This will check for any new versions once and then exit. Run with --watch to continuously check every minute. Use --interval to adjust the check period.

IFTTT

Both the await and notify subcommands print new versions to the console. The --ifttt option accepts an IFTTT webhook URL to notify when a new version is found. This notification can then be redirected to Twitter, Slack, email, printers, light bulbs, and hundreds of other places.

The event will have the following data set:

• Value1: The groupId:artifactId pair (e.g., com.example:example)
• Value2: The new versions that was seen (e.g., 1.1.0)
• Value3: Not used

Install

Mac OS

$ brew install JakeWharton/repo/dependency-watch

Other

Download ZIP from latest release and run bin/dependency-watch or bin/dependency-watch.bat.

Docker

The container runs the tool using cron on a specified schedule and will notify IFTTT.

$ docker run -it --rm
    -v /path/to/config:/config \
    -v /path/to/data:/data \
    -e "CRON=0 * * * *" \
    -e "NOTIFY_IFTTT=..." \
    jakewharton/dependency-watch:trunk

To be notified when sync is failing visit https://healthchecks.io, create a check, and specify the ID to the container using the HEALTHCHECK_ID environment variable.
