Variable annotation used for getting the URI of the current script.
The type of the variable annotated with
@SourceURI must be assignment compatible with URI.
It will be used to hold a URI object that references the source for the current script.
By default the URI
will be made absolute (which is to say it will have an authority) in the case where a relative path was used
for the source of the script. If you want to leave relative URIs as relative, then set
@groovy.transform.SourceURIdef sourceURI assert sourceURI instanceof java.net.URI
