I recently upgraded from v1.61 to v1.75 of Sauce OnDemand plugin for Jenkins v1.524. After doing so, all jobs using the plug-in encounter Null Pointer Exception when launching sauce-connect.

Job/SlaveDetails:

• Sauce connect launched on slave
• Slave had already been created and running jobs with Sauce Connect before the plug-in update
• Configured to use web driver
• Uses default sauce connect credentials (i.e. those set up in the master plug-in configuration)
• Bringing the slave offline, restarting it, and bringing it back online did not solve the problem

Plug-in Configuration Details:

• "Sauce Connect Working Directory" field blank
• "Disable Sauce Status Column?" unchecked
• "Use authentication details in ~/.sauce-ondemand?" unchecked
• Test Connection returns success

Log:

Starting Sauce OnDemand SSH tunnel on slave node
Launching Sauce Connect on ...
