With latest email-ext-plugin release(2.44), it has support for integrating email-ext task in Pipeline type job. We were using "Script Content" i.e ${SCRIPT, template="groovy-html.template"} in free style job to generate html emails, but it is not working in latest version of email-ext-plugin for Pipeline type job, when we try to put same in "body" field of email-ext step in pipeline.
