Possible solutions is put your dependencies in src/main/resources then in your pom :
<dependency>
groupId ...
artifactId ...
version ...
<scope>system</scope>
<systemPath>${project.basedir}/src/main/resources/yourJar.jar</systemPath>
</dependency>
Note: system dependencies are not copied into resulted jar/war
(see How to include system dependencies in war built using maven)
