About getting log predicates OR adding other new attribute to log

I tried to use log predicates but the link (Java Command Line Program) in the below link showed me an error message.
How can I get log predicates in my log? Is there any tutorial that I can use to use YAWL API for that?

Extracting YAWL Log Entries for Process Mining

YAWL can create process logs in XES format by simply selecting a specification in the control panel and clicking on "download log".

Unfortunately, the log that is exported there does not contain the log predicates that can be entered in YAWL specifications. These logs can only be extracted using the YAWL API. There is now a Java Command Line Program that extracts these log attributes.
