Not able to run MATLAB execution using shell script.

[Rachit Kumar]

Following is the shell script:

#!/bin/bash
matlab -nosplash -nodisplay -r "InitFileName='model_init',VariableList={'motorspeed' 'motorpositions' 'voltage'},SimStart=0,SimEnd=20,ModelName='jenkins_test_model';jenkins_matlab"

This works fine when I execute it from Terminal, but throws following error when I use 'Execute shell' to run the script:

[MATLAB_Jenkins_Integration] $ bash -xe /tmp/hudson567488996824014170.sh
+ /unsecured/jenkins/workspace/MATLAB_Jenkins_Integration/project/build.sh Build-102
/unsecured/jenkins/workspace/MATLAB_Jenkins_Integration/project/build.sh: line 2: matlab: command not found

Finished: FAILURE

It would be really great if someone can help resolving this problem. Thanks in advance!

Doesn’t matlab: command not found tell you what the problem is? If it works from the terminal but not under Jenkins, then the PATH is presumably different in the two cases. Did you try in from the terminal using the same userid that Jenkins runs under?

Frankly I am new to Jenkins and new to Linux environment as well!
How can I check what is th euserid jenkins is using and how do I set the PATH for that userid. Also I do not have root access, so will it be possible for me to change the PATH of Jenkins userid and and run the MATLAB simulation.
Thank you!

Another option is just to change the shell script and put the path in there (e.g. change matlab to /opt/matlab/bin/matlab or whether the matlab executable is)

Hello Richard,

Modification:

#!/bin/bash
/usr/local/MATLAB/R2014a/bin/matlab -nosplash -nodisplay -r "InitFileName='model_init',VariableList={'motorspeed' 'motorpositions' 'voltage'},SimStart=0,SimEnd=20,ModelName='jenkins_test_model';jenkins_matlab"

It gives the following error:

[MATLAB_Jenkins_Integration] $ bash -xe /tmp/hudson199216277896528528.sh
+ /unsecured/jenkins/workspace/MATLAB_Jenkins_Integration/project/build.sh Build-104

If you can execute matlab using your user account from terminal and you are using the same accoutn while running the job, add this line in your  "execute shell" step

export PATH=$PATH:/usr/local/MATLAB/R2014a/bin/

That should point to the correct executable. You can try the above step even if you are using other user account from jenkins (it may just work :) )

Vivek.

Hello Guys,

Thanks a lot for your input, the issue has been resolved. The problem is in the Project configuration. It was configured for Windows and I was running it on Linux. Sorry for your time, thanks a lot!
