Thanks Taher, that's quite a proposition.

I'm not sure quite sure what you mean by "moving from Gradle to plain Java". So my answer
below may be biased.
My preference would be to recommend to use Gradle as much as possible in all areas (eg: dev,
test, QA, stage and prod) and if it's not possible to use 
in one or several of the areas then to switch to plain Java.
What I mean by "to switch to plain Java" is, as we discussed already, is to simply copy the
the Gradle cache to a another location and to set the 
location of Gradle cache by a mean or another (eg http://markmail.org/message/irm2q3palp65kmqg
and sequel)
We may also want to advice to copy only necessary files (to avoid copy the Internet ;)). Something
like what I proposed (for another reason: OWASP-DC) 
in this comment

In other words, if you can't run Gradle in an area but this area is on the same LAN than your
test instance (most common) then

     1. You have plenty of disk space and your LAN is not a bottleneck, just copy the Gradle
Cache, change its location, et voilà
     2. You can't use the point 1 (ie you want to minimise disk space or/and LAN usage, or
it's not on the LAN) then a solution like in in my comment
        above can be used (copy only files OFBiz needs to compile and run).
     3. You may even compile in a location where you can use Gradle and then copy only the
OFBiz jars and the runtime ones, something like Pierre
        proposed in this comment

Then do we need to explain more, ie what you suggest below? It seems they are more related
to Gradle knowledge and I'd let that to users to work on.
