log4j.appender.file.File=@workPath@/logs/jazz.logThis line should be updated to reflect the value that you are using for your Jazz Team Server for System z @workPath@ directory, for example:
log4j.appender.file.File=/u/jazz/logs/jazz.log
The location of the log4j.properties file should be added to the Java™ options when you configure the installation. For more information see, Troubleshooting Ant with extensions for z/OS builds.
