Druid(0.12.1) unable resolve google-extension

hello! everyone.
I have a question about pulling druid-google-extension.

but always not be success.

First, I set following config:

druid.extensions.loadList = [“druid-datasketches”, “druid-hdfs-storage”, “ambari-metrics-emitter”, “mysql-metadata-storage”]

druid.extensions.pullList = [“io.druid.extensions.contrib:druid-google-extensions:0.12.1”]

And… Error message is following:

ERROR [main] io.druid.cli.PullDependencies - Unable to resolve artifacts for [io.druid.extensions.contrib:druid-google-extensions:jar:0.12.1.3.1.0.0-78 (runtime) -> < [ (https://repo1.maven.org/maven2/, releases+snapshots), (http://172.27.44.203/nexus/content/groups/public, releases+snapshots), (http://repo.hortonworks.com/content/repositories/releases/, releases+snapshots)]].

Looks like this can happen when there are issues reaching the repository (the hortonworks repo in this case).
