Hello guys, I am trying to build a custom connector but when I run

./gradlew :airbyte-integrations:connectors:source-custom:build

I get an error:

> Task :airbyte-commons:compileJava FAILED

What should I do? I am using java 11.0.17

Airbyte uses Java 17, check the tech stack here: https://docs.airbyte.com/contributing-to-airbyte/developing-locally

thanks, I'll take a look at it

I recommend to read https://docs.airbyte.com/connector-development/ and after https://docs.airbyte.com/operator-guides/using-custom-connectors

Thanks you so much for the recommendations. It will be very useful for when I finish the sources, however I am trying to connect the sources into the UI without uploading docker images to a repository, is it possible?

Yes, you need to build the image locally or in your Airbyte instance

and what should I do after building the docker image locally?

Change the version to

dev

in Airbyte UI
