ok i just realized that after the export DISPLAY=:<PORT_NUMBER>
I have the command : Xvfb :`expr "$BUILD_NUMBER" + "100"` & So using the plugin will have the same impact. But... in the plugin I don't see anything to use a free port number... it is said that the port_number will be the number of the build. So there will be risk for build to abord if the port_number is take by another job... Le jeudi 7 janvier 2016 15:05:33 UTC+1, iostrym a écrit : > > Thanks a lot.
