Pipeline Snippet Generator

The snippet generator generates an invalid syntax: mimeType: '' causes javax.mail.internet.ParseException: Expected MIME type, got instead of defaulting to text/plain.

mail bcc: '', body: 'ready to deploy my-app?', cc: '', charset: '', from: '', mimeType: '', replyTo: '', subject: 'ready to deploy my-app?', to: 'me@example.com'

Probably failing to default to use Util.fixEmpty.

I had the same problems.
I just change to use emailext, instead of mail.
It works.

As a workaround.

Remove:

mimeType = ''
charset = ''

to allow the mailer to use the defaults.

Example:

mail bcc: '', body: 'ready to deploy my-app?', cc: '', from: '', replyTo: '', subject: 'ready to deploy my-app?', to: 'me@example.com'
