22  * SnapshotVersion is like Version but holds extra fields that appear in the
23  * filename of a snapshot artifact. The toString() method is not overriden
24  * because the super implementation produces the correct string for navigating
25  * the directory structure of a plugin repository. The extra fields maintained
26  * in this class are needed for constructing the filename portion of a URL for a
27  * snapshot artifact where the qualifier and build number are replaced with a
28  * snapshot timestamp and build number.
