git tag: fatal: Failed to resolve 'HEAD' as a valid ref

Question

I am cloning a single branch from a repository and creating a tag in a python script. The commands are as follows.

git clone -b master --single-branch <repository adress>

git tag -a testag -m 'test'

It clones successfully but when it comes to adding the tag, it breaks with the following error:

fatal: Failed to resolve 'HEAD' as a valid ref.

Answer 1

I ran into the same issue and was able to fix it by changing from

git tag -a testtag -m 'test'

to

git tag -a testtag -m "test"

I was running in Windows 7. Hope this helps :-)
