BundleWorks writes log entries to the 'logs' directory inside the BundleWorks 'work' directory (i.e., $BUNDLEWORKS_WORK/logs). Logs files include the date in the filename, so finding the current log is a matter of finding the current date (or sorting a directory listing by date).
When an error occurs in BundleWorks, the details of that error are sent to the current log file. These details often provide information that can be helpful in figuring out what went wrong.
BundleWorks uses Java logging. By default, BundleWorks is comfigured with a log level of WARNING, which includes entries at the FATAL or WARNING level. At times it may be helpful to see more information in the logs. To change the log level, you can edit the file 'bin/include.sh' inside the BundleWorks work directory. Change WARNING to INFO on the following line to see additional log entries:
JAVA_PROPS="-Dlog.fileName=bw.log -Dlog.level=WARNING"
