While working on some new project examples for JBDS 4.1.1, I ran into an issue. I have a project within a project examples zip that has an empty src folder but requires that the folder be in place to compile properly. Talking with Snjeza, she mentioned that the code skips empty folders during the import process.

Is there any way to short-circuit that behavior for the "src" directory at least?

The workaround is to include a file (like a dummy txt file) in the empty directory so it's no longer empty before you export the project(s) as a zip to be used by the project examples wizard.
