No.

Set the artifact to SNAPSHOT.

A block file is exactly the same as the file in BLOCK-INF/block.xml with
one addition - it contains a reference to the jar within the
classloader.  Personally I just use blocks (referred to as standalone
blocks) because it gives me a little more flexibility on deployment (you
can play around with the block without having to rebuild the jar).

Cheers, Steve.
