NB and multiple projects

Hi all,
  I need some help to solve a blocking problem I have. :_(
I've made some NB projects (Java SE) that almost have the same structure:

project_dir
   |
   +- src
   |
   +- lib

and few more. Inside "lib" there are 4-5 jars needed for each project, added 
as "jar/folder" in the project libraries (either compile or run).

Then I have some dependencies relationships between those projects, currently 
managed with "add project" in NB, in the project libraries. Something like A->B-
>C<-B<-D with no circular dependencies.

Usually NB builds, for each project, a dist directory with the project jar 
file and inside the dist a lib directory with the libraries/jars of that 
project. The jar of the project has a manifest correctly pointing to the lib/*.
jar files. So, double-clicking on this jar project (yes, I'm on windows...), 
everything works.

But, when I build a project that depend on another project it also creates the 
dist and dist/lib dirs with the main project in the dist and inside dist/lib 
the jar of the base project on which the main depend. But there are no the jars 
of the "inner" project!

Is there a way to solve these dependencies issues, jars, manifest and so on 
with NB?
  Unfortunately I cannot use maven or introduce maven at this point of the 
project.

Help,

Marco
