NOTE: These instructions assume that you have Apache Maven installed. You will need to install Apache Storm to run the crawler. The version of Storm to use must match the one defined in the pom.xml file of your topology. The major version of StormCrawler mirrors the one from Apache Storm, e.g. for StormCrawler 1.x, use Storm 1.2.3, for StormCrawler 2, use Storm 2.2.0.
The easiest way to get started is to generate a brand new StormCrawler-based project using :
mvn archetype:generate -DarchetypeGroupId=com.digitalpebble.stormcrawler -DarchetypeArtifactId=storm-crawler-archetype -DarchetypeVersion=2.1
You'll be asked to enter a groupId (e.g. com.mycompany.crawler), an artefactId (e.g. stormcrawler), a version and package name.
This will not only create a fully formed project containing a POM with the dependency above but also the default resource files, a default CrawlTopology class and a configuration file. Enter the directory you just created (should be the same as the artefactId you specified earlier) and follow the instructions on the README file.
Alternatively if you can't or don't want to use the Maven archetype above, you can simply copy the files from archetype-resources.
Have a look at the code of the CrawlTopology class, the crawler-conf.yaml file as well as the files in src/main/resources/, they are all that is needed to run a crawl topology : all the other components come from the core module.
