This project uses the Gradle build system. Most IDEs such as Eclipse or IntelliJ have support for importing gradle projects.
The easiest method is to build it from the command line. cd to the project's root directory (where this README file resides) and execute:
./gradlew run
If you are using a Windows computer, you can run:
gradlew.bat run
Gradle will take care of fetching dependencies and building the project from there.
