Cannot access recordIssues in Jenkins Pipeline using Warnings Next Generation - jenkins

Question

I have a simple Jenkinsfile with a recordIssues step. The relevant code looks like this:
step([
$class: 'recordIssues',
aggregatingResults: true,
enabledForFailure: true,
tools: [pyLint()]
])
I have installed the latest version of the Warnings Next Generation plugin (https://plugins.jenkins.io/warnings-ng) but I run into the following issue:
[Pipeline] step
[Pipeline] }
[Pipeline] // node
[Pipeline] End of Pipeline
java.lang.UnsupportedOperationException: no known implementation of interface jenkins.tasks.SimpleBuildStep is named recordIssues
at org.jenkinsci.plugins.structs.describable.DescribableModel.resolveClass(DescribableModel.java:478)
Is it somehow possible to check that the extension is installed correctly?

Answer 1

This is my working version for a Python project CI configuration in Jenkins to use JUnit, PEP8, Pylint and Coverage reports:
...
stage('Test: Run') {
steps {
// Run my project tests.
sh 'coverage run manage.py tests'
// Dump coverage metrics to XML.
sh 'coverage xml'
// Run Pylint.
sh 'pylint --rcfile=.pylintrc my_project > reports/pylint.report'
// Run Pycodestyle (PEP8 checks).
sh 'pycodestyle my_project > reports/pep8.report'
}
post {
always{
// Generate JUnit, PEP8, Pylint and Coverage reports.
junit 'reports/*junit.xml'
recordIssues(
tool: pep8(pattern: 'reports/pep8.report'),
unstableTotalAll: 200,
failedTotalAll: 220
)
recordIssues(
tool: pyLint(pattern: 'reports/pylint.report'),
unstableTotalAll: 20,
failedTotalAll: 30
)
cobertura coberturaReportFile: 'reports/coverage.xml'
}
}
}
...
It works with Cobertura plugin, JUnit plugin and Warnings Next Generation. Python packages I used are the traditional coverage and pylint and for PEP8 I used pycodestyle.
Hope this helps somebody else, as finding good examples of this Jenkinsfile stuff is not easy.

Answer 2

Just for the record:
Jenkins v2.204.2
Jenkins Warnings Next Generation Plugin v8.0.0
stage('Static Analysis') {
steps {
recordIssues(
tool: pyLint(pattern: '**/pylint.out'),
unstableTotalAll: 100,
)
}

Answer 3

This works for me (Jenkins ver. 2.164.1):
stage('Static Analysis') {
recordIssues(
tool: pyLint(pattern: '**/pylint.out'),
unstableTotalAll: '100',
)
recordIssues(
tool: pep8(pattern: '**/pep8.out'),
unstableTotalAll: '100',
)
}
