I assume the stash in repo address ssh://git@stash/project/repo.git is declared in /etc/hosts? Can you try putting "proper" URI there?

dmnk89 · 2015-05-04T13:07:21Z

git push works properly so i assume that this is not the issue

adamdubiel · 2015-05-04T13:08:57Z

This is not so straightforward - jgit does a lot of stuff on it's own, not by delegating to git executable, so it's not 1:1. Connection negotiation, keys lookup etc is one of those things.

dmnk89 · 2015-05-04T13:11:17Z

ok, i added url to /etc/hosts and still same error

adamdubiel · 2015-05-04T13:12:41Z

Oh, i meant - can you use "proper" URI in your origin declaration, i.e. instead of ssh://git@stash/project/repo.git put ssh://git@mystash.com/project/repo.git.

dmnk89 · 2015-05-04T13:18:18Z

the configuration i copied is not same i am really using... I changed 'sensitive' data...

I found similar problem on: http://dev.eclipse.org/mhonarc/lists/jgit-dev/msg02479.html
and removing entry from known_hosts solved problem...

adamdubiel · 2015-05-04T13:23:26Z

Ah, okay, i misunderstood it then :) Issue solved then? I'm keeping up with newest versions of grgit, which in turn uses jgit, but i can possibly force some newer version of jgit to be used.

dmnk89 · 2015-05-04T13:24:20Z

this may not be important but real origin address uses ssh on port 2222

adamdubiel · 2015-05-04T13:27:05Z

I think it was the keys issue, now i remember troubleshooting this kind of issue few months back.

dmnk89 · 2015-05-04T13:27:05Z

Update of jGit should solve this issue... I can wait :)

adamdubiel · 2015-05-04T13:28:55Z

Okay, so i'm going to repoen this and change the title accordingly :)

dmnk89 · 2015-05-04T13:31:17Z

Hmm... according to this http://mvnrepository.com/artifact/org.eclipse.jgit/org.eclipse.jgit/3.7.1.201504261725-r
Newest version of jGit still uses jsch in version 0.1.50. Problem was solved in 0.1.51 so we will have to wailt for upgrade of jGit first :)

adamdubiel · 2015-05-04T13:34:27Z

I will just force version via gradle, patch bump should not change the API :)

adamdubiel · 2015-06-21T22:10:35Z

At last i had some time to hack axion-release - this is now fixed.
