Hello,
i´ve built a plugin that calls an external c#-Program to import some
things using the .Net-Framework.
Ok, during the development of the plugin everything works fine (The
program "*.exe" lies in a subfolder named "temp" of the project) because
the plugin is loaded from the project, so it has a real filepath which I
get using the getInstallUri-Method.
Now my problem: When I export the plugin as a jar the exe cannot be
launched because the file lies within the jar.
So is there any possibility to execute the program at this location or
if not, how can i export a plugin as a directory so that eclipse is able
to load the plugin like a jar (I just tried to extract the contents of
the exportet jar and add the directory to the eclipse-plugin folder but
as I´ve expected eclipse didn´t load the plugin).
Thanks for the moment!

Each bundle gets its own cache space. It should be cleaned up if the
bundle gets uninstalled, but otherwise I think it stays unless someone
runs with -clean.
In a headless build the shape of the built plugin depends on what the
containing feature says for the "unpack" attribute on the plug-in entry.
If not specified, the default is "true", which results in a folder.
If you are running productBuild.xml with a .product, and the container
feature is generated for you, then we guess, which is based on whether
or not the Bundle-Classpath has a '.' on it.

Thanks for your replies.
I´m sorry that I wasn´t able to answer earlier but there was too much to
do at other projects.
So this tip worked fine, thanks a lot!
