I'm running into a NumberFormatException when attempting to Publish Selenium Report with an HTMLTestRunner generated report. Tests are kicked off by Jenkins, all succeed, and the output file is generated to a directory in the Jenkins workspace that the user has permission to. I specified the full path to the directory and did not point to the HTML output file. I have attached the output file that Jenkins tries to parse.
