Sorry I forgot to mention I'm still building this locally. I've run into this issue:

[INFO] ------------------------------------------------------------------------
[ERROR] Failed to execute goal on project pinot-java-client-jdk8: Could not resolve dependencies for project org.apache.pinot:pinot-java-client-jdk8:jar:0.12.0-SNAPSHOT: Could not find artifact org.apache.pinot:pinot-common-jkd8:jar:0.12.0-SNAPSHOT in apache.snapshots (https://repository.apache.org/snapshots) -> [Help 1]

[ERROR] After correcting the problems, you can resume the build with the command
[ERROR]   mvn <args> -rf :pinot-java-client-jdk8

How to resolve the above? We should probably revert this change and understand why the dependency doesn't seem to get resolved for org.apache.pinot:pinot-common-jkd8:jar:0.12.0-SNAPSHOT. perhaps no such module is built?

Oddly in the build logs I do see pinot-comon-jdk8:
