How to checkout from SVN with Oomph?

Question

I try to write a Setup Project Model which installs Eclipse and also checks out the source code from SVN with Oomph 1.6.0.

I read Automating Project-specific Eclipse Setups with Oomph:

One big issue in the process of software development (especially, but not only for bigger teams) is the setup of a common IDE. There are many settings and Plugins that must be common to all project members:

• File encodings
• Target Platforms
• SCM-Linking to Git/SVN/CVS/…

so it seems possible. But I couldn't find any documentation for it.

I found under Additional Tasks and Git Clone... an extension for Git, but there is no extension for SVN.

I found Importing project set from SVN fails:

I'd like to implement a setup task which creates a set of projects defined with a team project set:

<setupTask xsi:type="projectset:ProjectSetImportTask" uRL="https://subversion.assembla.com/svn/MYPROJECT/user.psf">
    <description>User projects</description>
</setupTask>

I set the property url, but the task is not executed. With the help of the referenced link:

• With Help -> Perform Setup Tasks... you can manually trigger the setup tasks again

I could excute the task manually, but I got an exception:

How can I check out my source code automatically with Oomph 1.6.0?
