building confluentinc kafka-connect-hdfs

When I try to compile I get an error about a missing SNAPSHOT dependency.

The error looks something like this:

Failed to execute goal on project kafka-connect-hdfs: Could not resolve dependencies for project
io.confluent:kafka-connect-hdfs:jar:3.1.-SNAPSHOT: Failure to find
io.confluent:kafka-connect-avro-converter:jar:3.1.-SNAPSHOT in http://packages.confluent.io/maven/ was cached in the local
repository, resolution will not be reattempted until the update interval of confluent has elapsed or updates are forced

The HDFS connector uses a few dependencies which we sometimes use SNAPSHOT versions of during development of a new release in order to build and test against new features. If you want to build a development version, you may need to build and install these dependencies to your local Maven repository in order to build the connector:
