Nothing more, nothing less.

1. Edit src/main/webapp/WEB-INF/web.xml and change the value of context-param hello.name to whatever you like.
   • Consider marking web.xml --assume-unchanged.

     $ git update-index --assume-unchanged src/main/webapp/WEB-INF/web.xml

2. Execute the following

   $ ./gradlew clean build appRunWar
   
   # or...
   
   $ ./gradlew clean build appRunWar -PhttpPort=<your preferred port>
   
   # Debugging 
   $ ./gradlew clean build appRunWarDebug
   
   # or...
   
   $ ./gradlew clean build appRunWar -PhttpPort=<your preferred application listening port> -PdebugPort=<your preferred debugging port>

3. Browse to http://localhost:8080/, replacing 8080 with your preferred application listening port if you so configured. Don't forget to attach a debugger if you're running appRunWarDebug.
