Converting HTML to Wikimarkup

The script below takes the response that has a property called description in HTML format and convert that to wikimarkup.

import com.atlassian.jira.component.ComponentAccessor
import groovy.lang.GroovyClassLoader
import com.fasterxml.jackson.databind.ObjectMapper

//load the class
Class DefaultWysiwygConverter = ComponentAccessor.getPluginAccessor().getClassLoader().findClass("com.atlassian.renderer.wysiwyg.converter.DefaultWysiwygConverter");

ObjectMapper mapper = new ObjectMapper()
//response is passed in from the parent action
def payload = mapper.readValue(response, HashMap.class)

String descHtml = payload.description //get description from json body
def converter = DefaultWysiwygConverter.newInstance()                                                 
String descWiki = converter.convertXHtmlToWikiMarkup(descHtml)
return descWiki

Example payload

{
  "description":"<b>This text is bold</b>"
}

Output *This text is bold*
