Where to place Java classes belonging to a Java package inside a project?

I like to include some Java classes, that belong to a Java package in my Max project. If they do not belong to any package i can simply place them inside the code folder and Max/JVM will find them. But if they are are part of a package (i usually place all my classes inside a package prefixing with jm for a cleaner structure) the JVM expects them to be inside a folder "jm".

Unfortunately Max will move the *.class files back to the code directory as long as I have the "Keep Project Folder Organized" enabled. Does anyone have a solution for that? Can we exclude folders from being organized? Maybe with a startup action?

Cheers,

Jan
