My experience is that Maven quietly ignores your desire to keep things in the 
local repository and messes up your dependencies.  I would argue that 
invisibly making changes is NOT a good thing.

Part of the problem I described is due to Maven's quiet retrieval of different 
transitive dependencies.  If it had instead crashed the build with a message 
about an unresolved dependency, it would have been better.  That certainly was 
not a good thing, and it's laid right at Maven's feet.

Sometimes even a bad tool can be used effectively, if a person is aware of all 
the kinks and quirks and is willing to take the effort to work around them. 
Such tool's effectiveness under those conditions is not evidence of its goodness.

Maven sucks.
