Wondering if the -d option is already set by IDEA and if you try to set it yourself it is ignored?
1. Set the -d option and at the same time uncheck the "Close message view if not error occured" checkbox under compiler options.
2. After compliaton you will see a message saying "The -d option may be specified no more than once."
I want my RMI classes to be built to a different folder than the rest of the project classes.
