Add vi: ft without breaking the code

Question

I'm using vim to write Jenkinsfile which has a groovy synatx.

node {
  // Jenkins stuff to do
}

In order to force groovy syntax on a file without .groovy extension I added

# vi: ft=groovy

To the top of the file.

While this works in vim - Jenkins has issues treating this as groovy script and throws a syntax error.

Is there a way to work around this?

Answer 1

# isn't how you write a comment in Groovy, so you've created a file with incorrect syntax. Change it to a proper Groovy comment and you should be fine.

// vi: ft=groovy
