[Perforce-Plugin] Problems running p4 client "The system cannot find the file specified"

[Ribram]

Jenkins 1.456 with Perforce Plugin 1.3.10 on both Windows and Linux.

Cannot seem to invoke the p4 client (it is in the path).  Seeing the exception:

Caught exception communicating with perforce. Could not run perforce command.com.tek42.perforce.PerforceException: Could not run perforce command.

Notice 'cannot run program ""'

On the wiki screenshots there appears to be a way to set the path to your p4 client which I am not seeing.  Also clicking 'Advanced' P4 Executable shows an empty read-only dropdown box.

You need to setup the perforce installations in the main configuration page,

goto http://yourserver:port/configure

and scroll to find the perforce section and then click the add perforce button

enter the name of the installation and the path to the executable, of setup the automatic installation option.

Looks like the wiki screenshots show the versions pre 1.3.9 when this change was made.

Chris,

Yeah, the wiki is in dire need of an update...

I've slightly changed the behavior in 1.3.11 so that if there is no perforce installation defined, it will use 'p4' by default.
