Publishing newman-reporter-htmlextra reports with Jenkins html publisher fails - jenkins

Question

I am running newman with newman-reporter-htmlextra in a Jenkins pipeline, generating a html report which I want to publish via the jenkins html publisher.
This is the stage in the pipeline I´m using
stage('Newman tests') {
steps() {
script {
dir("${JENKINS_HOME}/workspace/myproject") {
sh 'newman run "./Collections/my_collection.postman_collection.json" --reporters cli,junit,htmlextra --reporter-junit-export "newman_result.xml" --reporter-htmlextra-export "newman_result.html"'
junit "*.xml"
}
}
publishHTML target: [
allowMissing: false,
alwaysLinkToLastBuild: false,
keepAll: true,
reportDir: '.',
reportFiles: 'newman_result.html',
reportName: 'Newman HTML Reporter'
]
}
This is running, and creating an entry Newman HTML Reporter in my Jenkins project.
However, when I open such a report, it is empty, pls check .
Any ideas?
Many thanks in advance,
Christian

I guess you are accessing the wrong folder when you want to publish your html result.
You are creating your file not in the regular jenkins workspace:
dir("${JENKINS_HOME}/workspace/myproject") {
sh 'newman run "./Collections/my_collection.postman_collection.json" --reporters cli,junit,htmlextra --reporter-junit-export "newman_result.xml" --reporter-htmlextra-export "newman_result.html"'
junit "*.xml"
}
After you are leaving the script{} you are accessing the original workspace of Jenkins so reportDir: '.' is not the same folder where your file is which means no file = no html can be displayed.
You have 3 choices here:
You create the file in the regular workspace of Jenkins
The HTML Publisher Plugin aims to the correct folder
Put the HTML Publisher plugin into the scope of your dir{} as you did with your junit plugin
To find out easily which folder you are accessing in which scope you can run an echo pwd. Do this once in the scope of your dir{} and once in the scope of your plugin then it should be clear that the reportDir of your plugin is wrong.
