git - Jenkins - How do I publish coverage report to github -

i trying use github-pr-coverage-status-plugin, documentation says need run following on master branch:

step([$class: 'mastercoverageaction'])

but when add pipeline following error:

java.lang.unsupportedoperationexception: can't find git_url or change_url in envs: {branch_name=master, build_display_name=#41, build_id=41, build_number=41, build_tag=jenkins-testci-master-41, build_url=https://jnkns-ci.myserver.com/job/testci/job/master/41/, classpath=, hudson_home=/var/jenkins_home, hudson_server_cookie=01f6aedeea333d1f, hudson_url=https://jnkns-ci.myserver.com/, jenkins_home=/var/jenkins_home, jenkins_server_cookie=01f6aedeea333d1f, jenkins_url=https://jnkns-ci.myserver.com/, job_base_name=master, job_display_url=https://jnkns-ci.myserver.com/job/testci/job/master/display/redirect, job_name=testci/master, job_url=https://jnkns-ci.myserver.com/job/testci/job/master/, run_changes_display_url=https://jnkns-ci.myserver.com/job/testci/job/master/41/display/redirect?page=changes, run_display_url=https://jnkns-ci.myserver.com/job/testci/job/master/41/display/redirect}     @ com.github.terma.jenkins.githubprcoveragestatus.pridandurlutils.getgiturl(pridandurlutils.java:85)     @ com.github.terma.jenkins.githubprcoveragestatus.mastercoverageaction.perform(mastercoverageaction.java:71)     @ org.jenkinsci.plugins.workflow.steps.corestep$execution.run(corestep.java:80)     @ org.jenkinsci.plugins.workflow.steps.corestep$execution.run(corestep.java:67)     @ org.jenkinsci.plugins.workflow.steps.synchronousnonblockingstepexecution$1$1.call(synchronousnonblockingstepexecution.java:49)     @ hudson.security.acl.impersonate(acl.java:260)     @ org.jenkinsci.plugins.workflow.steps.synchronousnonblockingstepexecution$1.run(synchronousnonblockingstepexecution.java:46)     @ java.util.concurrent.executors$runnableadapter.call(executors.java:511)     @ java.util.concurrent.futuretask.run(futuretask.java:266)     @ java.util.concurrent.threadpoolexecutor.runworker(threadpoolexecutor.java:1149)     @ java.util.concurrent.threadpoolexecutor$worker.run(threadpoolexecutor.java:624)     @ java.lang.thread.run(thread.java:748) finished: failure 

i have tried multiple ways inject these variables. in latest try, looked @ source code class, changed pipeline be:

pipeline {    agent    options {     skipdefaultcheckout()   }   environment {     // calling credentials() sets 3 environment variables     // git_hub  <username>:<password>     // git_hub_user <username>     // git_hub_psw <password>      git_hub = credentials('tmhjenkins')     docker_repo  = 'mobilityhouse'     docker_hub   = credentials('tmhitadmin')     git_url_property = "https://$git_hub@github.com/mobilityhouse/testci.git"   }    stages{     ...     ... stage('coverage & tests') {       steps {         sh 'pip3 install -e .'         sh 'make coverage-xml'         script {           currentbuild.result = 'success'           sh(script: 'export git_url_property="https://$git_hub@github.com/mobilityhouse/testci.git"')           env.git_url_property = "https://$git_hub@github.com/mobilityhouse/testci.git"           step([$class: 'mastercoverageaction'])         }       }     }  ... 

}

alas, fails too. how supposed use plugin within pipeline? appreciated.
