Hi Ludovic,

Actually I am the owner of the ucloud project on github :) so I can make any changes you suggested. Wil let you know if it will work.

Thanks!

Hello Boris,

It looks like you are almost there. Your project is hosted on Github,
but I don't support yet Git, so the debian/watch used to find the latest
version and get the upstream code is not generated by mh_make.

However there are lots of other packages which get their sources from
Github (basex, plexus-cipher, junit4, libjdom1-java), so you can study
their packaging using apt-get source <package>.

This watch file should in theory get the latest release of uCloud,
expect that it does not...

cat <<EOF > debian/watch
version=3
http://githubredir.debian.net/github/cyberb/uCloud/ (.*).tar.gz
EOF

You should ask the project owner to tag in Git the latest release,
otherwise it's not possible to know what to download. Or better, he
should use maven-release-plugin to create a release of the project.

After you get this detail sorted, then you should add those lines to
debian/rules:

get-orig-source:
uscan --download-version $(DEB_UPSTREAM_VERSION)
--force-download --rename

Finally, if you work on Ubuntu and use Launchpad, then you should store
your packaging in bzr:

sudo apt-get install bzr-builddeb
bzr init
mkdir .bzr-builddeb/
echo -e '[BUILDDEB]\nmerge = True' > .bzr-builddeb/default.conf
bzr add .

and you can build your package with

bzr bd

Well that's the usual procedure. In your case, since it's difficult to
get the upstream sources, you need to download them yourself and put
them in a tar.gz file which you should call ucloud_1.0.0.orig.tar.gz and
copy it in the parent directory. Doing so will make bzr bd / debuild
happy since they don't have to download the sources.

Consider also joining the Debian Java team, as it's full of active and
knowledgable developers (http://wiki.debian.org/Teams/JavaPackaging).
Once your package is ready, you can ask to include it in Debian and it
will land some time later into Ubuntu.

Cheers,
Ludovic
