We are trying to use a parametrized pipeline passing a string parameter called "REPONAME" and than choosing the "Pipeline script from SCM" and entering as "Repository URL" the following string:
https://gitlab.csi.it/technical-components/tecnologie/container/${REPONAME}.git
in GIT we use the webhook as this:
http://tst-jenkins-master.ecosis.csi.it/project/TEST_DOCKER_PIPELINE/docker-pipeline-globaleaks/buildWithParameters?token=4e9b91e3a3124e8082b443b9d2873a8c&REPONAME=globaleaks

The build console show us that the REPONAME variable is empty and does not get substituted in the process.
We already set the "Lightweight checkout" unchecked (with the option checked on the error is even worse)
The console output is:

Checking out git https://gitlab.csi.it/technical-components/tecnologie/container/${REPONAME}.git into /var/lib/jenkins/workspace/TEST_DOCKER_PIPELINE/docker-pipeline-globaleaks@script to read Jenkinsfile
