Can't use custom components for OpenStudio for Data Integration made by Talend Component Kit Developer

[MFundarek1649839991]

Downloaded Talend Open Studio for Data Integration 8.0.1. IntelliJ Idea (Windows). Set up the environment with Component plugin in IndelliJ. Build a component in maven a deployed it into the Studio. Also activated the development environment in STudio and the button is shown in GUI.

Got BUILD Success at every stage and I can see the new component in STudio m2 repository on filesystem. However the component is not shown in the palette after Studio restart or after button press. Any pointers?

hard to find where that comes from. but entries in config.ini seem to have ":" quoted including -

component.java.registry=C\:/tos/TOS_DI-20210915_1333-V8.0.1M12/configuration/components-registration.properties
