            ah, i think most people here have had the same issue

            if you follow these steps for now;

            • git clone git@github.com:grahamoregan/github-plugin.git
            • mvn package
            • scp target/github.hpi user@server:/var/lib/jenkins/plugins/github.jpi

            restart jenkins to pick up the change.

            make sure you haven't pinned the version of github.jpi because you'll want to get the update when the issue is resolved.

            Thanks a lot for your reply.

            It may sound like a silly issue, but i am completely new to git, i have tried to clone using the first step, but following error is thrown, any pointers to get pass through :

            $ git clone git@github.com:grahamoregan/github-plugin.git
            Cloning into 'github-plugin'...
            Permission denied (publickey).
            fatal: Could not read from remote repository.

            Please make sure you have the correct access rights
            and the repository exists.

            you need to add your public ssh key to github, alternatively, you could try cloning using HTTPS instead (i think that'll work);

            git clone git@github.com:grahamoregan/github-plugin.git

            I'm actually unclear why bindJSON can return null at all.
            But I'm not going to let that mystery block users.
