gh-pages: Missing persmissions in GitHub repo (release fails)

[oleg-nenashev]

Seems several GitHub permissions are missing on my account.

• mvn:release step was able to create an empty version (seems to be OK)
• the tag has been also added => commit & push operations work well
• winp-1.23 snapshot is also available on Maven Central
• I was able to commit to gh-pages directly ( db20e0c )
• Seems https://github.com/kohsuke/wagon-gitsite somehow takes a wrong Git installation or ignores GIT_SSH variable

[kohsuke]

I see that it is git pull that fails, not git push. What happens when you run git pull origin refs/heads/gh-pages manually?

[oleg-nenashev]

It works well. I suspect a wrong Git installation is being used by wagon-git ( I have Cygwin and msysgit installations)

[kohsuke]

I doubt the code is doing any PATH manipulation before forking off cmd.exe.

[oleg-nenashev]

According to the code, there's no such steps.
I'll try to release from Linux in order to have a clean reproduction scenario.

[oleg-nenashev]

• The same issue happens on Linux (I'll update the log)
• git pull origin refs/heads/gh-pages works well in the manual mode

-bash-4.1$ git pull origin refs/heads/gh-pages

Seems the issue has been caused by khuxtable/wagon-gitsite#10

[oleg-nenashev]

Nothing to do on winp side
