Jenkins Github Authentication error

[kyle rendon]

Hi, I am having some trouble getting a push to a branch.

I set up Jenkins to detect a Github web hook (which it is detecting successfully, and executing the build step) when I push to a remote branch on my personal GitHub, however, it returns this error after the build is completed:

Pushing HEAD to branch DevBranch at repo origin

 > git --version # timeout=10

using GIT_ASKPASS to set credentials 

 > git push https://github.com/user/project HEAD:DevBranch

ERROR: Failed to push branch DevBranch to origin

hudson.plugins.git.GitException: Command "git push https://github.com/user/project HEAD:DevBranch" returned status code 128:

stdout: 

stderr: remote: Invalid username or password.

Beyond this, i cannot confirm why this is occurring.

other notes: when i do a push, it does ask for a passphrase for my key during a push or pull.

How can I set up Jenkins to properly push in the Git publisher step?

Thanks in advance.
