How can I find it ?

Sorry, that documentation is outdated. To create a plug-in package to publish, upload it as a "plug-in package" to contribute.ultimaker.com.

But I'd like to see a complete example of the plugin code.
Can I find it here?

No, as it's not the way to create plug-ins any more we're not supporting that.

I secretly ported it to CMake though to be able to release my plug-ins on Github as well. For an example, I recommend you take a look at the Settings Guide releases, which are .curapackage files: https://github.com/Ghostkeeper/SettingsGuide/releases
You can also upload them to contribute.ultimaker.com and then before submitting it downloading a .curapackage for a certain SDK version again. You can then inspect the file.

You're probably best off just mimicking the structure of those .curapackage files. They are just .zip files with a bit of metadata and then the actual plug-in under files/plugins.

My CMake script that generates that file is here:

https://github.com/Ghostkeeper/SettingsGuide/blob/8c55f0ea7f32c7e21bfe4bbe87d0f296cb1f9c24/CMakeLists.txt#L128-L161

Essentially that just takes a fixed _rels and [Content_Types].xml file, generates the correct package.json with the version number and such, and then copies in all of the files that need to be packaged.
