A Jenkins 1.651 master and slave have been installed on a Windows Server 2012. I need a way to kill the slave from the master (I already have a job that start the slave). Could you please give me any advice on the best way to proceed?
A Jenkins 1.651 master and slave have been installed on a Windows Server 2012. The slave is dedicated to run Selenium tests, but most of the time it goes offline:
Build step 'Execute Windows batch command' marked build as failure
ERROR: slave-tester is offline; cannot locate jdk7
