{noformat}
Reason: is usually project formatted like this:
{noformat}
worx
.mvn
prj1
pom.xml
prj2
pom.xml
{noformat}
At level of {{.mvn}} there is no POM.
IMHO this is valid layout. Maven should not expect that there is pom.xml where
.mvn directory is. Is like is mixing rootDirectory and topDirectory?
Also, as we discussed, Maven _could come up_ with generated on the fly POMs for
such directories, to be able to build the complete tree structure: these POMs
are not parents (otherwise they would be referenced from prj1 or prj2 and they
missing would mean project is broken). They are really "just aggregator" POMs,
but subprojects can today be inferred, it means they need GA only, V=1 and
packaging=pom.
This means maven could generate these in memory with random G and V=relativized
path from rootDirectory parent?
