There should be build instructions in the README.md file, but more-or-less, you just need to do the following:
mvn clean install
cp socialpm-gwt/target/socialpm-gwt.war $DEPLOYMENTS_DIR
Wherever your deployments directory may be.
Right now the project is begging for help in the UI – I haven’t been able to port much from JSF to GWT yet, but if you’d like to help, I’d love it!
Sorry it’s not in a better state.
