I've used

But afterwards, no tags have made it into GitHub:

I've seen the FAQ, but to be honest I don't really understand it. The tags aren't showing up in the gitk UI either.

I did try using GitHub's own importer, but this didn't preserve any of the history which was very frustrating.

svn2git output:

CodePudding user response：

1. Your repo has non-standard layout (visible even of dirty screenshot) for tags, but you used command-line of standard SVN-layout
2. Build a real "plan" of tree for your repo
3. Read svn2git Readme carefully
4. Define all needed for your case options and option's values
5. Repeat export, check for (possible) errors
6. Repeat p.5 as much, as needed
7. Have fun

CodePudding user response：

svn2git was working correctly - I could see it when I ran git tag on the local repository svn2git produced.

But git push --all only pushes branches, not tags - I needed to run git push --tags as well.

Following this the tags were showing correctly.
