I'm trying to generate a readme file which looks as following:

not released yet

30c9474 myname 2018-08-23   Feature 1337



v1.0.76

420368f myname 2018-08-22   Changed Jenkinsfile.groovy again



v1.0.75

be05539 myname 2018-08-16   Feature 2833

838c158 myname 2018-08-16   Fixed bug 9128

6fa061a myname 2018-08-14   Feature 8832



v1.0.74

21903f2 myname 2018-08-11   Some stuff

57f1a2f myname 2018-08-05   Changed Jenkinsfile.groovy

this is how I generate my readmefile with jenkins currently:

node('master') {

    def artifactConfig = [

        version: '1.0.'+env.BUILD_NUMBER,

    ]



    try {

        // ######################################## Commit stage ######################################

        stage('Create Changelog stage') {

            // needs to be checked out again, because by default on master the sources are checkout out to ${WORKSPACE}@script in scripted pipeline

            checkout scm



            // the Changelog will be created here

            sh 'git log $(git describe --tags --abbrev=0)..HEAD --pretty=format:"%d%h%x09%an%x09%ad%x09%s" --date=short --all | sed "s/^ *([^)]*)/\n&\n/;1i (not released yet)" > releasenotes.md'



            sh 'git config --global --unset-all core.editor && git config --global core.editor $(which vim)'



            sh 'git add releasenotes.md &&' +

                'git tag -a version/' + artifactConfig.version + ' -m "Version version/' + artifactConfig.version + ' created" &&' +

                'git commit -C HEAD --amend --no-edit &&' +

                'git push -f origin version/' + artifactConfig.version

        }

    } catch (exception) {

        currentBuild.result = 'FAILED'

        throw exception

    }

}

That creates a readme file in a versioned branch.
My problem is that I don't know how I can put that file together as my example. All I figured out is how to generate a readme file like:

30c9474 myname 2018-08-23   Feature 1337

420368f myname 2018-08-22   Changed Jenkinsfile.groovy again

be05539 myname 2018-08-16   Feature 2833

838c158 myname 2018-08-16   Fixed bug 9128

6fa061a myname 2018-08-14   Feature 8832

21903f2 myname 2018-08-11   Some stuff

57f1a2f myname 2018-08-05   Changed Jenkinsfile.groovy

Edit:
This is how my network graph looks like:

With the help of jthill I changed my git log line to this:

sh 'git log $(git describe --tags --abbrev=0)..HEAD --pretty=format:"%h%x09%an%x09%ad%x09%s" --date=short | sed "s/^ *([^)]*)/\n&\n/;1i (not released yet)" > releasenotes.md'

but the result looks like this now:

(not released yet)

30c9474 myname 2018-08-23   Feature 1337

420368f myname 2018-08-22   Changed Jenkinsfile.groovy again

be05539 myname 2018-08-16   Feature 2833

838c158 myname 2018-08-16   Fixed bug 9128

6fa061a myname 2018-08-14   Feature 8832

21903f2 myname 2018-08-11   Some stuff

57f1a2f myname 2018-08-05   Changed Jenkinsfile.groovy

which looks better, but it's still not what I needed.

You can get the data you need in the sequence you need with

git log --date=short --pretty='%d%h %an %ad   %s'

from there it's straight text munging with your favorite tool. If you don't need it too pretty, piping it through

sed 's/^ *([^)]*)/n&n/;1i (not released yet)'

will do.
