... which will change 1.2.3-SNAPSHOT to 1.2.3-FEA-650-SNAPSHOT if the current checked-out Git branch is FEA-650.  You might need to consider replacing / with - in your branch-naming strategy, depending on what Maven thinks of it (I find the /s confusing, but that's just me), or modify the sed accordingly.
At worst this would allow you to remove your version-number from of your POM, so other POM changes can be safely merged and known to be non-version-number related - if necessary you can keep version numbers in another file, using a Maven Properties Plugin to load them and replace the entire version number if required.

 Q:

Java How do you declare a generic parameter to be any interface

I'm trying to learn some reflection in Java and I've run into a snag. Essentially I'm trying to create a really generic event system. Yes I know there are already many out there but this is more of an exercise in learning than anything practical. Anyway, I keep getting the following error when I declare an Instance of EventSource<PersonnameChangeListener, PersonNameChangeEvent>
error: type argument PersonNameChangeListener is not within bounds of type-variable ListenerT
    private EventSource<PersonNameChangeListener,
  where ListenerT is a type-variable:
    ListenerT extends Class declared in class EventSource

So My question is, "How do I declare that I want a generic parameter to be any interface?"
Thank you in advance,
Jec

... then draw creative with replace the version - string, for example you can: 
 mvn install -Dexternal.version - qualifier=$(git emblematic - ref --short HEAD| sed s_^master\$ _ _) 

... which will change 1.2.3 - SNAPSHOT to 1.2.3 - FEA-650 - SNAPSHOT if the current checked - out Git outgrowth is FEA-650.   You might need to consider replace / with - in your branch - naming scheme, depending on what Maven thinks of it (I find the /s confusing, but that's just me), or change the sed accordingly. 
 At worst this would leave you to remove your version - act from of your POM, so other POM changes can be safely unite and known to be non - version - number related - if necessary you can continue version numbers in another file, using a Maven Properties Plugin to load them and replace the entire interpretation number if required.
