my operator can not appear on RM after installextension

I try to build my own operator, I follow theinstruction from rapidminer github. But after I run "gradlew installExtension" (build successfull), I still can not see my operator on RM operator tree. What should I do?

You should check the rapidminer-studio.log file (located in the .RapidMiner folder) for plugin initialization or other errors.

Hi,

 

did you try to turn it off an on again? you need to restart studio so it reloads the jar.

This is my log, and I can't find any clue on that file.

It seems that you have not provided a name for your extension. So I guess the extension 'Extension Template' is your custom one. 

The gradle task initializeExtensionProject only creates the project structure, so please check the following documentation to create custom operators.

 

Cheers,

Marcel
