The Maven WAR overlay template will, out-of-the-box without any configuration, build a very basic “default” CAS server. This server doesn’t do much, but it will let us verify that everything we’ve done up to this point is working correctly and give us a starting point for further configuration and customization. To build the default server, run the commands
casdev-master# cd /opt/workspace/cas-overlay-template
casdev-master# ./mvnw clean package

on the master build server (casdev-master). Since this is our first time running mvnw, several hundred lines of diagnostic output will be printed as the wrapper downloads and installs Maven (to a cache directory), and as Maven downloads all the various software components that CAS servers are built from—CAS modules, Java libraries, third-party packages, etc.—from public software repositories and stores them in its cache. Once all that preparatory work is finished, the CAS application itself will be built:

The end result of a successful build will be a subdirectory called target that contains a cas.war file:
