Jenkins pipeline multiline shell with escape character

Question

I'm running into a weird issues with a pipeline script. I have a multi line sh blob like

sh """
   git tag -fa \\"${version}\\" -m \\"Release of ${version}\\"
"""

And this somehow runs as:

+ git tag -fa '"1.0-16-959069f'
error: Terminal is dumb, but EDITOR unset
Please supply the message using either -m or -F option.

So its dropping the -m and message. I've tried single escapes, double escapes, nothing seems to work.

Answer 1

I have no idea why this worked but this did

def tagGithub(String version) {
    def exec = """
    git tag -d ${version} || true
    git push origin :refs/tags/${version}

    # tag new version
    git tag -fa ${version} -m "Release of ${version}"
    git push origin --tags
    """

    sh exec
}

Something with the inline jenkins groovy interpolation seems busted, doing the interpolation in another var and then executing it worked
