mvn clean install to execute Cucumber test for executing a jar file

I am working on running Cucumber tests through Maven "mvn clean install" command. One of my tests including executing a jar file through the command line, eg - "java -jar -Dprop1:value... ./jarLocation

This test is working correctly locally in my IDE, but it fails to start the process and throws a Null Pointer exception during maven clean install phase. Would anybody have an idea as to how to get this Cuke test to execute jar file, working with Maven? Any suggestions would be very much helpful.
