[news.eclipse.platform.rcp] Exported product fails "plugin is invalid"

[Marc Schlegel <marc.schlegel@xxxxxx>]

Hi

After exporting my product I am not able to start the application and
the log says that my plugin is ivalid.
I know that this is a known problem and I found some post regarding this
problem but none says how to fix it.

I know that the classes have to be in the plugins root folder and NOT in
a folder bin. But when I create a new plugin the output directory is bin
by default. Does someone know how I can change this behavior so that my
classes are in the root folder? I've tried to make some changes in the
build.properties but it didn' work.

Thx
