How to import svn branches and tags into git-svn?

You’ll need several steps.

1. supply proper trunk, branches and tags folder names and fetch svn repo:

   git svn init -t tags -b branches -T trunk https://mysvn.com/svnrepo
   git svn fetch
   

2. Since tags in svn are real branches, create git tags from tag branches:

   git for-each-ref --format="%(refname:short) %(objectname)" refs/remotes/tags |  cut -d / -f 3- |
   while read ref
   do
     echo git tag -a $ref -m 'import tag from svn'
   done
   

3. Delete tag branches

   git for-each-ref --format="%(refname:short)" refs/remotes/tags | cut -d / -f 2- |
   while read ref
   do 
     echo git branch -rd $ref
   done
   

4. Since tags marked in the previous step point to a commit “create tag”, we need to derive “real” tags, i.e. parents of “create tag” commits.

   git for-each-ref --format="%(refname:short)" refs/tags |
   while read ref
   do
     tag=`echo $ref | sed 's/_/./g'` # give tags a new name
     echo $ref -\> $tag
     git tag -a $tag `git rev-list -2 $ref | tail -1` -m "proper svn tag"
   done
   

5. All we have to do now is to remove old tags.
