Configuring Jenkins with Bitbucket

Question

I seem to have got stuck trying to link Jenkins (an EC2 AWS instance of Ubuntu) with Bitbucket.

Whenever I try to build my project (I've installed the git plugin on Jenkins) I get...

Building in workspace /var/lib/jenkins/jobs/Google adwords/workspace

Fine - this looks like it's trying to go over ssh but can't find the keys. So I'm trying to generate the keys, under ~/.ssh I've got the files authorized_keys and known_hosts but according to the documentation here...

https://confluence.atlassian.com/display/BITBUCKET/How+to+install+a+public+key+on+your+bitbucket+account

I should have a file under ~/.ssh called id_rsa

I've been following the documentation...

https://confluence.atlassian.com/display/BITBUCKET/Using+the+SSH+protocol+with+bitbucket

But it looks almost either half finished or I'm missing the bit where the key gets put in the correct file.

Firstly - is my assumption correct this is an ssh issue? Secondly, if it is, does anyone know how to get the keys to match so Jenkins can make the pull and build?

EDIT : I assumed it was an ssh issue as the question Jenkins Build Using Git with Deploy Key was related, but I'm using bitbucket rather than github.

Answer 1

You need to generate the key file to upload to your BitBucket account. From the user that is running Jenkins, do the following:

ssh-keygen -t rsa

Take the default for the key file location and leave the passphrase blank. You'll then have the ~/.ssh/id_rsa.pub file to upload to BitBucket.

Answer 2

I was reading this post because I had the same problem and I have found something useful right now.

MY CONFIGURATION I have a slave building server (Win7-64 machine) where I have installed the standard Git (during installation I chose the third option: "Run Git and included Unix tools from the Window command prompt".) Jenkins is configured with Java Web Start.

I have noticed that if I execute from Git shell the command

ssh -vT git@bitbucket.org

I can authenticate with the server getting the message

You can use git or hg to connect to Bitbucket. Shell access is disabled.

BUT if i execute the same command from cmd, I get

Permission denied (publickey)

I'm not sure, but I think that Git plugin execute commands from the window shell and not with git shell (as I expected), so this could determine an authentication problem in the build.

In Git Plugin docs there is a little section called "Some windows fun" that suggest to copy the .ssh user's folder under Git folder (in my case C:\Program Files (x86)\Git).

After doing so, from windows shell I ran ssh -vT git@bitbucket.org and it worked (if it doesn't work, try to restart the shell or the entire machine). Then I ran the build from Jenkins and finally it worked.

I hope this could help.

Good luck.
