RFR 8209064: Make intellij support more robust after changes for 2018.2

[Magnus Ihse Bursie]

Hi Maurizio!

Even if this only incidentally relates to the build, please always 
include build-dev when making changes in the "make" directory.

As far as I can understand, your changes looks good. One question: the 
build.xml was previously stored as a "template", and copied to the 
output directory. Now it's left in the source tree. I assume that there 
was no actual transformations or changes made to the template before? So 
that the scripts do not modify the source tree version, that is.
