Environment:Hudson 1.355, Cobertura plugin 0.8.11
My build for some reasons produces an empty Cobertura report, like this:
<?xml version="1.0" ?> <!DOCTYPE coverage SYSTEM 'http://cobertura.sourceforge.net/xml/coverage-03.dtd'> <coverage> <sources> <source> /private/var/lib/hudson/workspace/myproj/client </source> </sources> <packages/> </coverage>
Whenever I load the project page or the Cobertura report page, I get an exception in the server log:
