Adaptavist ScriptRunner for Confluence Data Center - Missing Class "CopyTree"

[Stefan Rybinski]

Problem description:

Trying to migrate our internal atlassian plugin that uses ScriptRunner. After changing the versions of Confluence and ScriptRunner (see below) I got the following problem: 

The class com.onresolve.scriptrunner.canned.confluence.admin.copytree.CopyTree is missing in the Maven package.

We used the class to implement the same functionality as the CopySpace builtin Script,  but removing the CopyLabel part. Here are the affected LOCs

//import class
import com.onresolve.scriptrunner.canned.confluence.admin.copytree.CopyTree

//init CopyTree with a given Space
def copyTree = new CopyTree(targetSpace)

//get CopyInstructions and copy them to the target space
def copyInstructions = copyTree.getCopyInstructions(targetSpace, tmp, Closure.IDENTITY).copyInstructions
copyTree.copy(targetSpace, copyInstructions)

//copy blog posts
copyTree.copyOnePageOrBlogPost(blogPost, space, linksRewriter)

Without this Class our plugin is not buildable. 
Is there an alternative to the missing CopyTree class? 

Migration:

Confluence: 7.4.8 -> 8.5.9
ScriptRunner: 6.23.0 -> 8.28.0
