how to change subversion workspace format with a Groovy script?

[Nico Mommaerts]

Hey guys,

I'm trying to find out how I change the Subversion workspace format defined by the SubversionSCM plugin with a Groovy script?

This is what the plugin stores as configuration:

<?xml version='1.0' encoding='UTF-8'?>

<hudson.scm.SubversionSCM_-DescriptorImpl plugin="subve...@1.54">

  <generation>1</generation>

  <credentials class="hashtable"/>

  <workspaceFormat>10</workspaceFormat>

  <validateRemoteUpToVar>false</validateRemoteUpToVar>

  <storeAuthToDisk>true</storeAuthToDisk>

</hudson.scm.SubversionSCM_-DescriptorImpl>

I can query the value with this snippet:

Jenkins.instance.getDescriptorByName("hudson.scm.SubversionSCM").getWorkspaceFormat() 

But I don't seem to find a way to change it? I set a bunch of other options in the core and other plugins by using the descriptors but no cigar here.

Any suggestions?

Greets,

Nico
