Subject [jira] [Commented] (LUCENE-5850) Constants#LUCENE_MAIN_VERSION can have broken values

Just trying to understand why custom build would be too difficult anyway. I mean, perhaps
you have to make a small hack to the ant file or something, but that's fine.

Its currently attempted to be supported and thats why versioning is a mess (there are multiple
versions) and nobody understands what is going on. We have to just simplify it: its open source.
If you want to do something custom, my god you might have to change the source :)

> Constants#LUCENE_MAIN_VERSION is set to the Lucene Main version and should not contain
minor versions. Well this is at least what I thought and to my knowledge what the comments
say too. Yet in for instance 4.3.1 and 4.5.1 we broke this such that the version from SegmentsInfo
can not be parsed with Version#parseLeniently. IMO we should really add an assertion that
this constant doesn't throw an error and / or make the smoketester catch this. to me this
is actually a index BWC break. Note that 4.8.1 doesn't have this problem...
