Proxy for branch indexing in multibranch pipeline

[Lionel Orellana]

Hi

I have a proxy configured in my Jenkins settings (Manage Plugins -> Advanced). 

I'm pretty sure this is what makes freestyle jobs and Pipelines set the proxy before connecting to github. 

Here's the output from a Pipeline job:

 > /opt/rh/devtoolset-2/root/usr/bin/git config --local credential.helper store --file=/tmp/git7252640829815953814.credentials # timeout=10
Setting http proxy: serverproxy:8080

 > /opt/rh/devtoolset-2/root/usr/bin/git -c core.askpass=true fetch --tags --progress https://github.com/****/*****.git +refs/heads/*:refs/remotes/origin/*

But when I try to run the indexing job in a Multibranch pipeline it fails to connect to github. It seems to me it is not setting the proxy.

Is there a way to set the proxy or could it be something different?

Thanks

Upgrading from 1.656 to 2.0 fixed it.

The GitHub Branch Source Plugin is probably what made the difference. I was using a Git (as opposed to GitHub) branch source before.

I'm facing the same problem, but I do not want to upgrade to 2.0. Would appreciate other suggestions.

There shouldn't be anything specific in Jenkins core affecting this. When Lionel upgraded he probably upgraded his plugins at the same time. Make sure you are running the latest version of GitHub Branch Source and Branch-API plugins and see if that fixes it.

It was the switch from the Git branch source to the GitHub branch source what probably fixed mine. I only found there was a github one whe I upgraded.

[Tarek Nabil]

Well, the problem is, my code is not on GitHub; it's on BitBucket.

The question is: what is the branch indexing doing differently from any other job that uses Git? We have like a hundred jobs and none of them has Git connectivity issues. It just seems that in this particular case, the proxy configuration is not used.

Is there any update on this? I am accessing a github enterprise repo and it also seem to not using the proxy settings...
