Failure to build Airbyte from master

Hey all,
I’m following the steps to build Airbyte for local development to be able to test a change to a connector I’ve been working on.

However, when running SUB_BUILD=PLATFORM ./gradlew build I get:

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':spotlessJava'.
> java.lang.reflect.InvocationTargetException

This is happening even on master for me. Any help is appreciated

More details:

You don’t need to build the platform to change a connector version. You can build the connector using ./gradlew airbyte-integrations:connectors:your-connector:build
Do you have all tech stack and what head/commit are you in master?
