Oh, I think I remember there are some customers who has jar files that don't
quite follow the industry standard that would use a "-" before the versions,
like abc.1.0.jar, they would like abc.1.1.jar to replace abc.1.0.jar.

I think the "intuitive" nature of the versioning means we have to have a
standard jar file format, so that the system can intuitively understand that
"some-jar-0.2" is the update to "some-jar-0.1". There HAS to be some form of
format for the auto-version-update to work, otherwise one could never compare.
Maybe I'm just trying to be more explicit. That way, any implementation of
the "deploy jar" functionality can rely on a single fact, that the jar files
will be in a known format.
The alternative is maven-like in behavior... then we don't have to deal
with explicit file formats. When a jar is deployed, the feature behaves more
maven-like, and "artifact name", "version" and file path is required. That way,
the jar file does not ever have to meet the required format. All information
required has been provided by the user. Removes the false-positives that could
be introduced.
As there is no public API here, the only change we would have to deal with
is the gfsh scripting, which I assume is not so horrible.
Anyway.. just thoughts..

The goal of the GEODE-7436 change is that when user deploys

*both* deployed, which is bad!
In the weird example below of spark-network-common_2.11-2.3.1.jar, it
is harmless that we stem it as spark-network-common_2 (*if* for some very crazy
reason a user NEEDS both spark-network-common_2.11-0.0.0.jar and
spark-network-common_2.12-0.0.0.jar deployed side-by-side, they can simply
rename the jar to something more sane)

probably concerned that user's jar name might contain "_" or "-" themselves,
like common-logging.jar etc. So we had to resort to finding the first "."
followed by a digit to determine where the version pattern begins.

“spark-network-common_2.11-2.3.1.jar” is incorrectly classified and has the
WRONG artifact name. As “spark-network-common_2.11” is the correct artifact
name NOT “spark-network-common_2”!

This would be a “breaking” change, but we should change this sooner than
later. There is no transition ability here, as it would be too hard to have
Geode support both, as there is no simple way for the system to decide if the
name conforms to the “correct” format or not.
