Maven: The Definitive Guide

Building the Multimodule Project

With the simple-weather project containing all the general code for interacting with the Yahoo! Weather service and the simple-webapp project containing a simple servlet, it is time to compile and package the application into a WAR file. To do this, you will want to compile and install both projects in the appropriate order; since simple-webapp depends on simple-weather, the simple-weather JAR needs to be created before the simple-webapp project can compile. To do this, you will run mvn clean install from the simple-parent project:

~/examples/ch06/simple-parent$ mvn clean install [INFO] Scanning for projects...
