This repository contains the Maven crawlers for VersionEye and requires Maven 3.3.9. This project contains:

• A Maven Crawler which works via HTML. It can crawl the HTML representation of a Maven repository
• RabbitMQ consumers/workers for HTML/Index crawlers.

There is always 1 crawler which walks ever through a maven index or it's HTML representation but doesn't download and parse any pom.xml files. It only sends the coordinates to a Queue (RabbitMQ). There can be N consumers/workers which do the heavy lifting, the downloading and parsing of the pom.xml files. That way it's relatively easy to scale the crawling processes.

This project contains a docker-compose.yml file which describes the backend services of VersionEye. You can start the backend services like this:

docker-compose up -d

That will start:

• MongoDB
• RabbitMQ
• ElasticSearch
• Memcached

For persistence you should comment in and adjust the mount volumes in docker-compose.yml for MongoDB and ElasticSearch. If you are not interested in persisting the data on your host you can let it untouched.

Shutting down the backend services works like this:

docker-compose down

As primary database we are using MongoDB. To make this project work you need to configure the MongoDB connection in versioneye_maven_crawler/src/main/resources/mongo.properties. If you run MongoDB as a single instance, only fill out the first 3 lines.

To configure the RabbitMQ connection adjust the settings in versioneye_maven_crawler/srm/main/resources/settings.properties.

To start the RabbitMQ consumer/worker for the maven indexer run this command:

mvn crawl:maven_index_worker

That will spin up a RabbitMQ worker which waits for messages from the maven-indexer project.

To start the RabbitMQ consumer/workers for the maven HTML crawler run this command:

mvn crawl:html_worker

That will spin up a RabbitMQ worker which waits for messages from the HTML index crawler.
