Problem when generating JUnit report on Jenkins Pipeline - jenkins

Question

I'm creating a post job on Jenkins pipeline to publish test results using junit, html and cobertura. The code looks like this
post {
always {
publishTestResults(
script: this,
junit: [
active:true,
allowEmptyResults:true,
archive: true,
pattern: '**/reports/mocha.xml',
updateResults: true
],
cobertura: [
active:true,
allowEmptyResults:true,
archive:true,
pattern: '**/coverage/cobertura/cobertura-coverage.xml'
],
html: [
active:true,
allowEmptyResults:true,
archive:true,
name: 'NYC/Mocha',
path: '**/coverage/html'
],
lcov: [
active:true,
allowEmptyResults:true,
archive:true,
name: 'LCOV Coverage',
path: '**/coverage/lcov/lcov-report'
]
)
cobertura coberturaReportFile: 'coverage/cobertura/cobertura-coverage.xml'
junit 'reports/mocha.xml'
cleanWs()
// deleteDir()
script {
FAILED_STAGE = env.STAGE_NAME
}
}
}
}
The problem is when I execute the job on Jenkins I receive an error message:
find . -wholename **/reports/mocha.xml -exec touch {} ;
touch: cannot touch './reports/mocha.xml': Permission denied
I suppose the issue raised by junit command. How could I solve this problem?
P/S: Jenkins server runs on Ubuntu. I tried to modify /etc/sudoers and add this line to make Jenkins executes command as root. It still could not solve my problem.
jenkins ALL=(ALL) NOPASSWD: ALL

From checking the code at: https://github.com/SAP/jenkins-library/blob/5c13a0e2a20132336824c70b743c364bcb5341f4/vars/testsPublishResults.groovy#L136
Looks like you can avoid the issue by setting updateResults to false
If you absolutely have to update the timestamp on the result file, you'll have to open a terminal session, go to the project workspace (with jenkins user) and try to run touch ./reports/mocha.xml and then debug it from there.
