Jenkins Pipeline - Jmeter Performance report - jenkins

Question

I have the below Jenkins pipeline script to run the jmeter tests and make a report from a JTL file
node('master') {
stage 'Run JMeter Test'
def workspace = pwd()
def jmeterTestFile = 'jenkins_test'
echo "workspace = ${workspace}"
echo "env.WORKSPACE = ${env.WORKSPACE}"
bat "${workspace}\\jmeter\\bin\\jmeter.bat -n -t ${workspace}\\jmeter_scripts\\${jmeterTestFile}.jmx -l ${workspace}\\jmeter_scripts\\${jmeterTestFile}_results.jtl"
step([$class: 'ArtifactArchiver', artifacts: 'CP-Perf-Report.html,**/*.jtl, **/jmeter.log', fingerprint: true])
//perfReport "jmeter_scripts\\${jmeterTestFile}_results.jtl"
performanceReport parsers: [[$class: 'JMeterParser', glob: "jmeter_scripts\\${jmeterTestFile}_results.jtl"]], relativeFailedThresholdNegative: 1.2, relativeFailedThresholdPositive: 1.89, relativeUnstableThresholdNegative: 1.8, relativeUnstableThresholdPositive: 1.5
}
Initially I tried creating report with perfReport "jmeter_scripts\\${jmeterTestFile}_results.jtl" command but it was failing with FileNotFoundException so I tried alternative way using performanceReport parsers but even then its failing again with FileNotFoundException but I can manually open the c:\tools\jenkins\workspace\PerformanceTesting\jmeter_scripts\jenkins_test_results.jtl file and see the test report. can anyone help me to fix this issue?
workspace = c:\tools\jenkins\workspace\PerformanceTesting
[Pipeline] echo
env.WORKSPACE = c:\tools\jenkins\workspace\PerformanceTesting
[Pipeline] step
Archiving artifacts
Recording fingerprints
[Pipeline] step
[Pipeline] }
[Pipeline] // node
[Pipeline] End of Pipeline

I don't see any sign of running a JMeter test in the log so I would recommend amending your pipeline script as follows:
Convert \\ slashes into / ones
Given you are running your test on Windows I believe you should be using variables in form of %WORKSPACE% rather than ${workspace}
