At the of the "In-process Script Approval" page, where you have "No pending script approvals" as per your picture.

Dav z, do you have security enabled in Jenkins? You will see entries there only if security is enabled.If you don't have security enabled then you don't need to approve groovy scripts. They should work without script approval.

I couldn't repro this issue on my machine. I use 0.63 version of the plugin on jenkins 1.654.

here is how my configuration screen looks like.

here is how the build page looks like

Can you check the Jenkins system log to see there are any exceptions there?
You can find this under 'Manage Jenkins'

vimil, yes I have security enabled in /configureSecurity/

Digging a bit int the log show that a script required approval, so wend back to the approval page and this time there was an approval button.

So now I can embed a groovy script. But it seems that I cannot load it . I tried both using the the absolute path and relative to the Job but nothing shows up. Also nothing comes up in the log file when the file cannot be found

So If I understand correctly, you can use the groovy script option but not the groovy script-file option?

correct I can create an inline script [where you type the script in the text area] fine. The script is excuted correctly.

But when I try to use an external file, nothing is happening. I checked the jenkins log and there are no file not found.

Maybe is the path incorrect, which one should I use ? Absolute or relative [to what in case] ?

Dav z,

You should use an absolute path. Let me verify that I am able to repro your issue and get back to you

I tested this with version 0.63 version of the plugin on jenkins 1.654. and was not able to repro the issue. Below is the screenshot of my configuration.

I can use a groovy script. There was problem with a regex I was using in the script. Thanks and sorry of the trouble.

I am marking this issue as cannot repro

All worked at the end for me. Using the absolute path did the trick
