svn.debian.org (Alioth) has two different types of repositories.
Select repository which you should use.
Read http://wiki.debian.org/Alioth/CollabMaintImport at first. Then, execute following commands to dump.
SVNROOTPATH=/your/svn/root/path/of/repos
PKGBASEDIR=debian
PKG=your-package-name
workdir=`mktemp -d` && pushd $workdir
# dump your package
dumpfile=$PKG.svndump
svnadmin dump $SVNROOTPATH \
| svndumpfilter --renumber-revs --drop-empty-revs include $PKGBASEDIR/$PKG \
1> $dumpfile 2> dumpfile.error
perl -i.bak -npe "s|^(\S+-path: )$PKGBASEDIR/|\$1|" $dumpfile
# restore test
svnadmin create $workdir/collab-maint
svn mkdir file://$workdir/collab-maint/deb-maint -m "Initial directory creation"
svnadmin load $workdir/collab-maint --parent-dir deb-maint < $dumpfile \
> load 2> load.error
test ! -s load.error && echo "Succeeded"
# check restored
svn list file://$workdir/collab-maint/deb-maint
svn log file://$workdir/collab-maint/deb-maint/$PKG
# additional tests
svn co file://$workdir/collab-maint/deb-maint/$PKG
pushd $PKG/trunk && svn-buildpackage -uc -us
popd
# copy dumpfile to svn.debian.org
scp $dumpfile svn.debian.org:
# remove working dir
popd && rm -rf $workdir
After that, you can restore dumped file into svn.debian.org.
# log into svn.debian.org
ssh svn.debian.org
# check repository
svn list file:///svn/collab-maint/deb-maint
# or svn list file:///svn/collab-maint/ext-maint
# load file to repos (replace dumpfile with real filename)
svnadmin load /svn/collab-maint --parent-dir deb-maint < dumpfile > load 2> load.error
test ! -s load.error && echo "Succeeded"
# check restored (replace your-package-name with real package name)
svn list
svn log file:///svn/collab-maint/deb-maint/your-package-name
At last, checkout your repository and build.
svn co svn+ssh://svn.debian.org/svn/collab-maint/deb-maint/your-package-name
cd your-package-name
svn-buildpackage
