Once upon a time, in IDEA I could define libraries that had only sources.
They were sources for jars that were included in the project classpath.
An attempt to navigate to one of those classes, the source from the
library was opened.
(examples of why this is useful to me : I used to browse the many sun
sources licensed separately from the binary product, eg the JDK sources,
javax stuff etc).
This is not possible now - eg IDEA now opens a decompiled stub in the
is this a bug or a limitation of the new project/module/library design ??
