Analyze R code in Jenkins

[mitevski79]

I have set up a workflow to analyze R code in Jenkins, the result is sometimes different, the same code can lead to opposite build results. What is the exception with the zero pointer mentioned in the sonar analysis step here? ->

    ERROR: Error during SonarScanner execution

Did you run LintR before actually running SonarQube scanner? The stacktrace is saying that the JSON file for LintR outputs is empty.

I have checked it - and apparently the source file to be consumed by the sonar-scanner command has already been created prior to invoking the sonar-scanner command. Moreover, I output the content of the file with a "cat" command - and it is not empty.
