  • I have been trying to use Workflow to check out a secured Subversion repository. My script is this: def creds = com.cloudbees.plugins.credentials.CredentialsProvider.lookupCredentials( com.cloudbees.plugins.credentials.common.StandardUsernameCredentials.class, Jenkins.instance, null, null ); def cid = creds[0].id node { checkout scm: [ $class: "SubversionSCM", locations: [ remote:'https://secure3.svnrepository.com/myrepo/trunk', credentialsId: cid] ] } I have only one credential stored in Jenkins, the one for the svn repo, so that's why I am grabbing it programatically. The output is: Running: Allocate node : Start Running on master in /var/jenkins_home/workspace/WorkflowTest Running: Allocate node : Body : Start Running: General SCM Running: Allocate node : Body : End Running: Allocate node : End Running: End of Workflow java.lang.ClassCastException: sun.reflect.generics.reflectiveObjects.ParameterizedTypeImpl cannot be cast to java.lang.Class at
