Incremental Maven releases to Kafka

NOTE: This scraper is not working anymore since maven-repository.com is down.

This Python script scrapes maven-repository.com and forwards it to Kafka. The scraper script requires: start_date, kafka_topic, bootstrap_servers and sleeptime. It will scrape all releases until start_date and push this to the kafka_topic running on bootstrap_servers. It will keep repeating after sleep_time seconds with start_time == date_of_latest_release. I.e. it scrapes incremental updates on Maven releases.

Prerequisites

Install all dependencies:

python3 -m venv venv
. ./venv/bin/activate
pip install requests BeautifulSoup4 kafka-python

How To Run

usage: Scrape Maven releases to Kafka. [-h]
                                       start_date topic bootstrap_servers
                                       sleep_time

For example:

python scraper.py '2019-06-24 14:05:50' cf_mvn_releases localhost:29092 60

This will scrape up to 2019-06-24 14:05:50 (+ incremental updates) pushes it to cf_maven_releases located at localhost:29092. Incremental updates are checked every 60 seconds.

Note: start_date must be in %Y-%m-%d %H:%M:%S format. Multiple bootstrap servers should be , separated. Sleep time is in seconds.

Sample data

Data will be send in the following format:

{
  "groupId": "com.g2forge.alexandria",
  "artifactId": "alexandria",
  "version": "0.0.9",
  "date": "2019-06-24 14:42:49"
}

Run in Docker

docker build -t mvn-scraper .
docker run mvn-scraper '2019-06-24 14:05:50' cf_mvn_releases localhost:29092 60

or alternatively

docker run wzorgdrager/mvn-scraper '2019-06-24 14:05:50' cf_mvn_releases localhost:29092 60
