* </p>
* <p>Currently, resource name has the following form:</p>
* <pre> DIR{/DIR}/FILE[:CLASS] </pre>
* <p>
* where <code>DIR{/DIR}/FILE</code> is a "file" part containing full name
* of a file (file path) in TunedIT Repository and
* <code>CLASS</code> is an optional "class" part
* which contains a fully qualified name of a Java class contained in the file
* (the file is expected to be a JAR file in such case).
* If present, the class part is separated from the file part by a colon ":".
