      Jenkins pipeline errors out with Null pointer exception when I am using Jacoco plugin. If I comment out the Jacoco step from Jenkinsfile then there is no error thrown. The log file in Jenkins indicate that the error is thrown after the End of Pipeline. Any idea why this error is thrown?

      Jacoco plugin version: 3.30

      Jenkins war version: 2.319.1

          I was able to solve the issue with correct jenkins statements. See <https://stackoverflow.com/questions/70274194/null-pointer-exception-in-jenkins-pipeline-when-jacoco-plugin-is-used/70352254#70352254>

          The instruction step() should not contain jacoco() statement
