Checkout SVN with credentials in Jenkins pipeline?

Question

How can I check out a Subversion repository that requires user credentials, via a Jenkins pipeline groovy script? It appears that the built-in svn command doesn't support credentials, so I tried code like this:

node {
    stage 'checkout'
    withCredentials([[$class: 'UsernamePasswordMultiBinding',
                      credentialsId: '34761a89-1402-47d7-96e2-aec22ffdc50b',
                      usernameVariable: 'USERNAME', passwordVariable: 'PASSWORD']]) {
        sh "svn co https://trac.nci.org.au/svn/cable/branches/$SVN_BRANCH --username $USERNAME --password $PASSWORD cable_branch"
    }
}

But this fails with

groovy.lang.MissingPropertyException: No such property: USERNAME for class: groovy.lang.Binding
    at groovy.lang.Binding.getVariable(Binding.java:63)

What am I missing?

Answer 1

You can use the Snippet Generator for General SCM step. This displays the familiar Subversion configuration options, and takes credentials as parameter as usual.

The Snippet Generator will produce a tad ugly representation of your parameter selections and looks something like this:

checkout([$class: 'SubversionSCM', 
          additionalCredentials: [], 
          excludedCommitMessages: '', 
          excludedRegions: '', 
          excludedRevprop: '', 
          excludedUsers: '', 
          filterChangelog: false, 
          ignoreDirPropChanges: false, 
          includedRegions: '', 
          locations: [[credentialsId: '34761a89-1402-47d7-96e2-aec22ffdc50b', 
                       depthOption: 'infinity', 
                       ignoreExternalsOption: true, 
                       local: 'cable_branch', 
                       remote: "https://trac.nci.org.au/svn/cable/branches/$SVN_BRANCH"]], 
          workspaceUpdater: [$class: 'UpdateUpdater']])

Notice that the remote section uses double quotes, so that the variable $SVN_BRANCH gets substituted correctly.
