You may create local repository on your project
For example if you have libs folder in project structure
In libs folder you should create directory structure like: /groupId/artifactId/version/artifactId-verion.jar
In your pom.xml you should register repository
<repository>
<id>ProjectRepo</id>
<name>ProjectRepo</name>
<url>file://${project.basedir}/libs</url>
</repository>
and add dependency as usual
<dependency>
<groupId>groupId</groupId>
<artifactId>artifactId</artifactId>
<version>version</version>
</dependency>
That is all.
