The simplest and clean way to do that (actually svn 1.9, released 2015) is using:

svn info --show item revision [--no-newline] [SVNURL/SVNPATH] 

The output is the number of the last revision (joungest) for the SVNURL, or the number of the current revision of the working copy of SVNPATH. The --no-newline is optional, instructs svn not to emit a cosmetic newline (\n) after the value, if you need minimal output (only the revision number).
