Jenkins can't pull local Git repo - v1.536

[Julien Tanay]

Hi, 

Since this morning - and I absolutely don't know why! - Jenkins is not able to pull from any of my local repository.

Builds that worked yesterday don't today. The only error i got is this Exception :

FATAL: Username may not be null

java.lang.IllegalArgumentException: Username may not be null

at org.apache.commons.httpclient.UsernamePasswordCredentials.<init>(UsernamePasswordCredentials.java:90)

But I didn't change anything to my settings.

I am using a Jenkins user.

From the command line, I am able to pull my repositories (with the exact same credentials).

I'm lost here. Did you ever seen such an Exception ?

Thanks for your help, 

[Julien Tanay]

PS : I'm using Jenkins 1.536 with :

GIT Plugin 2.0

GIT client Plugin 1.4.5

SSH Credentials Plugin 1.5.1 (STRANGE ; previous version was 0.3!!!)

Check if you have git user.name set.

Hi Julien,

we are experiencing exactly the same problem. Just came out of nowhere.

Have you been able to find out something?

Best regards

Igor

I'm wondering if this is somehow related to https://issues.jenkins-ci.org/browse/JENKINS-20262. Can you try rolling back to 1.535?

Hi, 

Thanks for your answer. I wasn't able to do anything about it.

I'll rollback Jenkins to 1.535 ASAP and I'll keep you in touch.

 -- Just an update :

Tried to upgrade to 1.357 : same issue. I'll try to rollback tomorrow.

[Julien Tanay]

Hello all, 

ERRATUM : the version I tried yesterday was 1.537 and not 1.357.

I downgraded my Jenkins 1.535 and found the exact same issue ... "Username may not be null".

But which username ???

Thx, 

Julien

Did you try setting up the git credentials again? They may have become corrupted via the 1.536 issues.

Hi Slide, 

On the server side or on the Jenkins side ?

Thx, 

Julien

Hi,

On the Jenkins side.

Hi all, 

After upgrading again to 1.537, I changed the git credentials just to see if it works...

Well now I don't see the error anymore, but when I try to pull from my local gitlab (on the same machine than Jenkins) during a build job, getting a 503 error :

"Failed to connect to 'http://gitlab.myserver/my/repo.git' (status = 503)"

I Tried to check on the build configuration side the adress of my GitLab repository : I get a 504 error...

That's wierd...

Thanks for your help, 

Julien

Hi all, 

It was a proxy issue... my bad...

I had to save proxy settings again after the upgrade and that did the trick.

Thanks all for your help. I hope this thread could help someone else !
