Installed my own extension but can´t find it in operator tree

Hello,

I developed my first operator and installed it. IntelliJ shows me that that the build was successful and
that the task "installExtension" is finished and i can see that the extension was loaded in the "About Installed Extensions" - menu. However I can not find my operator in the operator tree. Any suggestions what the reasons could be?

Best Regards

Hey @duken,
very hard to debug, because it can have quite a few reasons. Any chance you can share the code?

Otherwise, anything in the rapidminer-studio.log which looks odd?

Best,
Martin

Hey @duken,

That's weird, typically is should be a child of extensions folder in operator, did you try restarting Studio. Also checkout this thread https://community.rapidminer.com/discussion/56872/tutorial-for-creating-custom-operators/p1?new=1.

Hi @hbajpai,

Thanks for your answer.
yes I rebuilt and reinstalled it multiple times but it´s still not there.
The weird thing is when I was doing the "Extension-Tutorial" I could find the empty operator in the tree.

Hey @mschmitz,

thanks for your answer but I managed to get it to run now.
The problem was an NullPointerException.
Checking the .log definitely helps.

Hi @duken,
great! I am still curious about what you are building

Let me know if I can beta test!
