Generic-hub is a Grails web application that is aimed to be an example implementation of the ALA Biocache (occurrence record search interface). There is very little code in this project as most of the functionality is provided by a Grails plugin called biocache-hubs. If you intend to create your own custom skinned version of the Biocache webapp, then this is the project you should clone/fork as a starting point.
First download and install Grails (Note: version 2.3.x is currently required but check the
for the specific version). Fork this project to your local machine.
Then try running the app with the command line:
cd generic-hub grails run-app
