You need Maven 3 (at least 3.0.4) and Java 8 or later to build Tobago.
In the project directory you can use:
mvn install
to run the install target on all sub projects. This will put all necessary artifacts into your local repository.
Switch to sub-directory and call Maven to run the demo:
cd tobago-example/tobago-example-demo mvn clean jetty:run -Pjetty
