How to get Matlab output in Jenkins console [duplicate]

Answer 1

You need to add -wait to the MATLAB command.

On Windows, Jenkins wraps the command in a batch file that returns immediately, and therefore doesn't capture the output (and by the way, it will also always exit with a success status even if MATLAB itself didn't).

By adding -wait, it will delay the exit until MATLAB has finished, and it will also return with the appropriate exit status.

PS Also see this excellent series of posts by @AndyCampbell on integrating MATLAB with Jenkins.

Edit:

The above works for me. But here's a couple of other things I would check, as they've been gotchas for me when I was getting it set up - perhaps they will help you too:

1. Make sure the build step is an "Execute Windows batch command" step rather than an "Execute shell" step, as it's a pain to get the unix utilities installed and running on Windows
2. Make sure that you have the right type of quote marks in the MATLAB build command. They need to be straight quotes, not curly quotes - both the single and double ones
3. If you copied and pasted the MATLAB build command into Jenkins, make sure you didn't accidentally paste in any extra invisible characters - try typing the command directly into Jenkins
4. Make sure there are no licensing issues - for example, Jenkins may be running as user1 and will call MATLAB as user1, but MATLAB is licensed to user2. If you call MATLAB with -nodesktop in this case it will just silently fail (and may even leave a zombie MATLAB process hanging around, with an invisible license error dialog, that you can only quit from with Task Manager)
5. To assist in troubleshooting, you can add -logfile \path\to\logfile.txt to your MATLAB command, which can diagnose some issues. You can also use a startup.m file and/or a finish.m file - these should run at startup (before your build command) and just before exit (after your build command). Finally you could try using a build command that does something simple to the filesystem, rather than a disp (this would diagnose whether it's an issue with MATLAB running at all, or an issue with Jenkins collecting its output).

Answer 2

I finally manage to get the matlab output in the console. I follow a tip given in @AndyCampbell blog by @Guy Starbuck:

start /wait matlab -nodesktop -nosplash -minimize -wait -r "disp('Hello World!');exit" -logfile unittestlog.txt
set output=%errorlevel%
MORE unittestlog.txt
EXIT %output%

thanks all for your help.
