maven-indexer

This Maven project is using org.apache.maven.indexer/indexer-core to fetch and read maven indexes. Unfortunately the indexer-core project still relies on Maven 3.0.5. With higher versions of Maven the indexer-core is not running correctly.

This project is only fetching and reading Maven indexes from different repository servers. The project checks if the artefact is already in the VersionEye DB or not. If the artefact is a new one it sends a message to the RabbitMQ server with the corresponding coordiantes. There are different RabbitMQ workers running on Maven 3.3.X withe Eclipse Aether, fetching and parsing the actual pom file and writing the new artefact to the VersionEye DB.

Start the backend services for VersionEye

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

MongoDB Config

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

RabbitMQ Config

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

Maven Index Directory Config

The Maven Indexer is downloading the maven index to a local directory. The working directory for that can be configured here: srm/main/resources/settings.properties.

Dependencies

This project relies on versioneye_persistence and versioneye_service. These projects are currently located in the crawl_j project. Run

mvn install

on the crawl_j project to install the dependencies.

Run

To start the crawler for Maven Central, run this command with Maven 3.0.5:

mvn crawl:central

This will fetch the maven index form Maven Central and iterate through it. If it finds an Artifact which is not yet in the MongoDB, it will send a message to RabbitMQ. To make this fully work it is required that at least 1 RabbitMQ consumer is running which is processing the message from this project. The code for the consumers are located in the versioneye/crawl_j project.

This command will fail if you run it with a Maven version higher than 3.0.5!
