Previously I was using plugin to handle few files in one report.
The config is :
HTML directory to archive = target/html-reports
Index page[s] = report.html,results.txt
Report title = TestReport
Keep past HTML reports= true
Always link to last build = false
Allow missing report=true
After upgrade to 1.7
The report doesn't handle those files and displays no tabs at all. See attached screenshot.
No warning was in job console output.
