If you want to compile the examples based on JESS, set the environment variable JESS_HOME to the home directory where your jess program has been installed. Default behaviour: IDLJ task is being skipped. WARNING: SubWCRev is being skipped. The copyright notice of JADE Runtime will not be updated WARNING: Executing the idlj task might create wrong java files tagging new release: JADE-${version} executing SUBWCRev to set revision number and date for this JADE Trying to compile the examples based on JESS. If the JESS library is not included into the CLASSPATH, a number of errors will be generated by the compiler but the task will contine. REMINDER!!!!!
