[pde-build-dev] Problems with package script and gzipped tars

[Urs Reupke <ureupke@xxxxxxxxxxxxxx>]

Hi,
I am working with Markus Knauer on the Eclipse Packaging Project,
and (following Pascals advice in the e.t.packaging NG) have written some 
code to use the PDE Packager to create distributable RCP applications 
from (more or less) thin air.

The code uses features and plugins retrieved from update sites in 
conjunction with the root files of the RCP.
Said root files are my reason for writing to you, since the packager 
does not work properly if the Packager Map refers to the root file 
archived as a gzipped tar archive instead of a zip.
In the documentation[1] it is "suggested that you build *nix packages on 
a *nix machine to ensure that file permissions are preserved." This 
could also mean that .tar.gzs are not supported as an input format - 
does it?

Moreover, there's a (presumably related) problem with the packager's 
output: No matter the specified output archive format for a platform, 
the files end up being called ".zip".
When the archive format is set to "antTar", this ".zip" is actually a 
broken .tar.gz, while setting the format to simple "tar" yields a 
gzipped tar with the correct contents (and just a 'wrong' file name.)
Is this a problem easily overcome by configuring the packager correctly, 
or is there something wrong with my system setup?

Thanks for your support
-Urs
