Multi-Branch project with svn externals

[Lars Meynberg]

We have setup a multi-branch project with a Jenkinsfile. The detection is working fine but we're using external links for some stuff and everytime when the projects start it fails with an authentication error:

org.tmatesoft.svn.core.SVNCancelException: svn: E200015: authentication cancelled

In the single pipeline script it works because we have setup ignoreExternals like this:

 checkout scm: [$class: "SubversionSCM", locations: [[remote: '*****',

                    clean: true, local: '.', ignoreExternalsOption: false]]]

but as the Jenkinsfile has only checkout sum I'm not able to add this setup to it. Or needs this to be setup in the config of the multi-branch project? But there is only the option for the remote url and nothing else.

So I'm grateful for any tipps to solve the authentication problems (All found issue we're solved by bugfixes in the past and seems not related) or to add the ignoreExternalsOption to the multi-branch project.

Kind regards Lars
