FileNotFoundException after running git pack-refs

[parasyte]

git pack-refs --all changes the .git internal structure, placing all refs in .git/packed-refs and deletes the individual files in .git/refs/. This can also be done implicitly by other commands like git gc.

The plugin will then crash as it tries to lookup a non-existing file:

lein-tar/src/leiningen/tar.clj

Line 65 in 09f253c

(.trim (slurp (str (io/file git-dir ref-path))))

FWIW, anyone who hits this issue can work around it by unpacking refs with this script: https://github.com/tj/git-extras/blob/7f0f91b4d429a11fdaecd5ad4c03c733470b07a1/bin/git-unpack-refs

I think we probably did this to avoid shelling out to git. What's a good solution here?

[parasyte]

My guess would be catching the exception and parsing the .git/packed-refs file in the exception handler.

10 internet points on offer if you put that up in a PR - except check for the file and fall back to the packed location instead of doing Flow Control Through Exceptions.
