Using Jenkins email-ext plugin with pipeline

Question

I am running from my pipeline a snippet to send html mail from HTML file. it looks like that:

emailext(to: "${BUILD_USER_EMAIL}", mimeType: 'text/html', subject: "dummy subject", body: readFile 'pipeline/mail/summary.html');

My question: How can I embed image file (as part of the mail) using CID or something similar? it only works if I am adding the IMG tag to my HTML file linking to a url that actually available from my org. I just need the image to be embedded as part of the mail. Thanks, Nir

Have you done anything similar in a freestyle job? Or is this a more general question if email-ext plugin supports it at all? — Jon S
I just need to know how to embed image in emailext use in pipeline (not freestyle). — Nir Koren
Yes I understand that, however I did some research and found no obvious way to do it in general (regardless of pipeline or freestyle). So I'm just wondering if you have managed to do it in a freestyle job and now are trying to convert that to pipeline? — Jon S

You can embed an image via base64. Convert the image here or however you want then enter it into your pipeline script like this:

(example is from Jenkinsfile)

emailext attachmentsPattern: '%JENKINS_HOME%/changelog.xml', body: '<img src="data:image/png;base64,iVBORw0K...shortened...rkJggg==">', mimeType: 'text/html', subject: 'Look at this subject!', to: '[email protected]'

Very important, the latest version can only support up to 65535 characters in the body and the encoding can easily surpass that limit.
