A typo that killed every stage before stage one

My Jenkinsfile called emailtext instead of emailext, and was missing the commas between arguments.

That was not an email bug. A declarative pipeline is compiled as Groovy before anything executes, so the parse error meant not a single stage ran.

Two more in the same file

• docker build -t $IMAGE_NAME was missing its trailing . build context
• A docker run was split across lines with no \ continuation, so the shell read it as two separate commands

Takeaway

If the stage view is empty, suspect the Jenkinsfile itself rather than the steps inside it.
