title: Specifying system properties or command line arguments when starting a daemon created using appassembler maven plugin
body: <p><br> we would like to use appassembler-maven-plugin to generate daemon scripts for our apps, we want to avoid having multiple configuratoins and generated scripts for the different environments, e.g. test, prod, etc., and would like to be able to set a jvm system property or add an extra command line argument when starting. I have been looking into this for a while ow and can't seem to find a solution.<br>
  If anybody has any ideas or suggestions they would be greatly appreciated,<br><br>
  thanks</p>
