The latest release can be downloaded from SourceForge
Apropos uses Git Version Control System. Public repo is hosted at GitHub . To get the source, once you have installed Git, issue this command:
$ git git://github.com/azzazzel/apropos.git apropos
This will make a new folder called "apropos" containing the working copy as well as cloned repo.
Apropos uses Maven build system so you need to have Maven installed in oder to build Apropos. To generate WAR file simply execute:
$ mvn package
This will compile classes and generate apropos.war in a folder called target.
Having apropos.war (either downloaded or built from source) all you have to do is to copy it into the webapps directory of your application server (e.g. Tomcat or Jetty). Then point your browser to http://localhost:8080/apropos
