Maven dependency on web application - maven

Question

My Eclipse project is structured as such:
my.core.webapp (libs, java classes, web.xml, etc)
my.extended.webapp (libs, java classes AND a dependency to
my.core.webapp)
my.core.webapp pom:
<project>
<modelVersion>4.0.0</modelVersion>
<groupId>my.company</groupId>
<artifactId>my.core.webapp</artifactId>
<version>1</version>
<packaging>war</packaging>
<build>
<sourceDirectory>src</sourceDirectory>
<plugins>
<plugin>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.5.1</version>
<configuration>
<source>1.7</source>
<target>1.7</target>
</configuration>
</plugin>
<plugin>
<artifactId>maven-war-plugin</artifactId>
<version>2.6</version>
<configuration>
<warSourceDirectory>WebContent</warSourceDirectory>
<failOnMissingWebXml>false</failOnMissingWebXml>
</configuration>
</plugin>
</plugins>
</build>
<dependencies>
.
</dependencies>
</project>
my.extended.webapp pom:
<dependency>
<groupId>my.company</groupId>
<artifactId>my.core.webapp</artifactId>
<version>1</version>
<type>war</type>
</dependency>
when I compile with maven I get various package xyz does not exist exceptions.
Is there a way (without having a 3rd project or using modules) to achieve that?

Answer 1

You will have to do 2 things here.
The first thing will be to add <attachClasses>true</attachClasses> to your maven war plugin configuration in my.core.webapp pom.xml. So now it should look like
<plugin>
<artifactId>maven-war-plugin</artifactId>
<version>2.6</version>
<configuration>
<attachClasses>true</attachClasses>
<warSourceDirectory>WebContent</warSourceDirectory>
<failOnMissingWebXml>false</failOnMissingWebXml>
</configuration>
</plugin>
The second thing to do will be to add <classifier>classes</classifier> while you are specifying my.core.webpp as a dependency in your my.extendend.webapp pom.xml. So it should now look like
<dependency>
<groupId>my.company</groupId>
<artifactId>my.core.webapp</artifactId>
<version>1</version>
<type>war</type>
<classifier>classes</classifier>
</dependency>
That should be all.

Answer 2

I managed to solve the problem based on #ritz-xavi answer.
my.core.webapp pom:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<version>3.0.0</version>
<configuration>
<attachClasses>true</attachClasses>
<webXml>${basedir}/WebContent/WEB-INF/web.xml</webXml>
<failOnMissingWebXml>false</failOnMissingWebXml>
</configuration>
</plugin>
my.extended.webapp pom:
<dependency>
<groupId>my.company</groupId>
<artifactId>my.core.webapp</artifactId>
<version>1</version>
<classifier>classes</classifier>
<type>jar</type>
</dependency>
<dependency>
<groupId>my.company</groupId>
<artifactId>my.core.webapp</artifactId>
<version>1</version>
<type>war</type>
</dependency>
Including both the war and the jar classes did the trick.
