Simone Bordet commented on ARCHETYPE-519:
-----------------------------------------
Robert,
that a URL has never been a valid value for {{archetypeCatalog}} is obviously
false, since it works fine with 2.4 and it's indeed what everybody here uses in
2.4 as a workaround for the removal of this exact feature in 3.0+.
So in summary: nobody asked for this feature change, no discussion about it
that I could find (please link if there was), it went in as a surprise breaking
change in 3.0, the community complains about the 3.0 change in this issue, and
there is denial of evidence when people reports the breakage.
Can you please report the rationale behind this change ? If it was driven by
community discussion, is there a link ? Otherwise, why has this change been
made, and why there is so much resistance in restoring its functionality when
the community asks for it ?
