There are new releases of PLDoc and downstream Maven projects.
I found some problems with identifying calls to standalone objects (PROCEDURE and FUNCTIONS); I also encountered problems running the 2 Maven plug-ins, possibly because they were dependent on different versions of PLDoc and PMD.
The response was to issue all 4 Maven projects with aligned core versions:-
PMD - 5.0.3
PLDoc - 1.3.11
If you do request plscope - PLScope identifier and call information is merged with PLDoc parse information.
The side-effect of this is an XML file that has call graph information within the PLSCOPE elements, including FUNCTION/PROCEDURE/TRIGGER node information (either PLScope SIGNATURE or an XML generated-id) - edge information is signature to signature.
I am going to see what is possible when I combine the PLDoc information with the graph - I am interested in hearing about anything that you find to do with it.
