declarative scripted pipeline: clone from mercurial with --stream

[Christoph Fetzer]

Hello!

Another weird issue I ran into:

For any reason it's not possible to clone from my repository without the extension largefile and the commandline switch --stream (or --uncrompessed, I tried both).

I therefore enabled this in the tools settings of mercurial:

When cloning from my jenkinsfile in this way:

            steps {
                checkout changelog: true, scm: [$class: 'MercurialSCM', source: 'http://XXX/hg/XXX/'
                    , credentialsId: 'XXX'
                    , modules: 'src', clean: true ], poll: false
            }
   

this unfortunately does not seem to be applied.

The output is looking like this:

I read the log as MercurialSCM would apply the tools settings only during jenkins internal housekeeping (e.g. clone of the jenkinsfile) and not during the checkout step from the jenkinsfile. In the docs of the checkout step I did not find a way to apply these settings.

Any ideas for me? Is it a failure of MercurialScm?
