Unable to create dev image of an existing destination connector

yes, you need to compile the code first to build the Docker container. I think now you have java-base image locally it’s possible to run using gradlew or Intellij to compile the destination connector.
./gradlew airbyte-integrations:connectors:destination-oracle:build , in the :airbyte-integrations:bases:base:airbyteDocker

I tried building both images and it is back to square one.

You must run the script build_image.sh manually and capture the error is throwing to you.
