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,

    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. :smile:

    Best regards
