I am having troubles getting Selenium Grid to start Selenium Server on slaves. When I try manually starting Selenium server on the slaves it works great.
I am getting this error all the time:
[12/09/14 17:15:48] [SSH] Starting slave process: cd "C:\cygwin64\home\$USER\selenium-server" && java -jar slave.jar
<===[JENKINS REMOTING CAPACITY]===>channel started
Slave.jar version: 2.48
This is a Windows slave
Starting Selenium nodes on Thor IE11 - Win8.1
$ "C:\Program Files\Java\jre1.8.0_25\bin\java" -Dwebdriver.ie.driver=C:\cygwin64\home\$USER\selenium-server\IEDriverServer.exe -cp C:\cygwin64\home\$USER\selenium-server\slave.jar hudson.remoting.Launcher -cp C:\cygwin64\home\$USER\selenium-server\selenium-server-standalone-2.41.0.jar -connectTo localhost:57416
ERROR: Unexpected error in launching a slave. This is probably a bug in Jenkins.
