Deploy your JAR to your local (file) Repository. You shold also commit this to your CVM System. You can also add JARs as Javadoc or Source.
    mvn deploy:deploy-file \
        -DgroupId=<group-id> \
        -DartifactId=<artifact-id> \
        -Dversion=<version> \
        -Dfile=<path-to-file> \
        -Dpackaging=jar \
        -Durl=file:///<project-dir>/repo 
        ( -Dclassifier=javadoc | sources  )
You can now use these JARs in your pom File if they were in a normal Repository:
    <project>
        ...
        <repositories>
        ...
            <repository>
                <id>project.local</id>
                <name>project</name>
                <url>file:${project.basedir}/repo</url>
            </repository>     
        ...
        </repositories>
        ...
    </project>
