java.lang.Exception when cloning a repo on GitHub [message #1734993] Tue, 14 June 2016 10:05 Go to next message
Eclipse UserFriend
I got this question in the Scout forum, and I think it is better to answer it here.

source: [neon] [oomph] import Demo app - auth failed
René Eigenheer wrote on Tue, 14 June 2016 13:11
I did some "playing around with Oomph".
Using Eclipse Neon RC3 I've created a fresh workspace and tried the following:
1. File - Import...
2. Oomph - Projects into Workspace
3. selected "Eclipse Projects - Scout - Scout Demo App"

installation process started, IDE restarted and afterwards I've got the following error:

any idea?


Hi René,

I think you are trying to clone the repository over Git SSH.

Is your SSH Key correctly updated on GitHub? When you try to clone the repository, did Eclipse prompt an "provide your passphrase" box like this one:

index.php/fa/26165/0/

To change the way you clone the repository you should activate the checkbox "Show all variables" and switch the value in "repository": try "HTTPS (read-only, anonymous)".

index.php/fa/26166/0/

In that case, you will not be asked for any password and "git-clone" should work.

thank you Jeremie, changing to anonymous https did the job.

BTW: I don't know why, but the Scout RT import worked without changing anything.

It's not clear if that subproject included a git clone task. In the
end, questions about Scout's setup should be directed to a Scout
forum... We can only help provide the basic facilities but can't answer
questions about how all projects have authored their setup tasks.
