This was indeed the answer - use the gitlab protocol and specify a branch e.g.

Iceberg enableMetacelloIntegration: true. 
Metacello new 
  baseline: 'PagerDuty';
  repository: ���gitlab://macta/WillowPagerDuty:master/src';
  load.

Thanks Gaby

I think you can use:
Metacello new 
  baseline: 'PagerDuty';
  repository: 'gitlab://macta/WillowPagerDuty:master/source';
  load.

or something like that

Hi - I���m trying to automate the deployment of a seaside image to Digital Ocean. I was following the Enterprise Pharo booklet - and its a bit out of date, but I wanted to do the bit about taking a clean image and then loading in my project which I���ve stored in Git using Iceberg.

So on the command line I am trying to eval ���
Iceberg enableMetacelloIntegration: true. 
Metacello new 
  baseline: 'PagerDuty';
  repository: 'git@gitlab.com:macta/WillowPagerDuty.git';
  load.���

But I get retry errors and a walkback, so I���ve tried to do the same in the playground in a fresh image and its true - I get an error because ZnClient is trying to connect to a url like "http://:80/git@gitlab.com:macta/WillowPagerDuty.git/?C=M;O%3DD��� (so it interprets that git@ specification strangely). 

But what is weird, is that if I use Iceberg - connected to the same repo (and specified the same way) - and then use the Metacello - Install baseline menu (right click on the BaselineOfXXX package) it then works perfectly.

So what���s the difference? It looks like the latter is mapping down to a "repository: 'gitlocal://', packageDir;��� whereas the above is trying to read it over the wire?

I then tried using an access token for gitlab, so its an https variant - but that gave me an error as well? Does this mean to automate I have to bring down the initial BaseLine - but then if that baseline refers to others - that seems to work, so I���m a bit confused about what is going on?
