title: Maven - Best way to refer to a directory on the system path
body: <p>I am trying to build an RPM from my Maven project. I have 5 different modules and each one has its own pom.xml, In the root I have one pom.xml which builds all modules (Typical Maven Setup). When I build an RPM, I want to include a directory that is not part of the maven directories. Its above a directory [from the root folder that contains my maven modules]. What is the best way to include that in my RPM? or rather what is the best way to refer to a directory with out hardcoding the path? I am confused about ${baseDir} and what it refers to?</p>
  
  <p>Thank you.</p>
