Maven Dependency to WAR module

So today, I had to create a new project, which was needed to have a dependency on another internal WAR module. 

The way to do that, is through the WAR module itself.

In the build tag, inside my WAR pom, under plugins I added:

<plugin>

   <artifactId>maven-war-plugin</artifactId>

   <version>2.1-beta-1</version>

   <configuration>

       <attachClasses>true</attachClasses>

   </configuration>

 </plugin>

When deploying your WAR module, the above plugin creates a JAR file with all the classes of your project (along with your WAR). This JAR will be accessible to your new project. In my case, I am deploying in an internal repository server (Apache Archiva). Bellow you can see the contents of my module directory inside Apache Archiva after deploying.

In the POM of my new project under the dependencies tag, I added the dependency to my WAR module as seen bellow:

<dependency>

   <groupId>${project.groupId}</groupId>

   <artifactId>e-receipt-api</artifactId>

   <version>1.2</version>

   <classifier>classes</classifier>

 </dependency>

The above code snippet resulted to including the produced JAR file with its classes.
