Building Salesforce adapter/translator pair issues

I tried to follow the instructions on https://github.com/teiid/salesforce to build a newer adapter/translator pair but I was not even able to build the provided v34 pair.
The "mvn clean install" produce the following error:

[ERROR] Failed to execute goal on project connector-salesforce-34: Could not resolve dependencies for project org.jboss.teiid.connectors.salesforce-34:connector-salesforce-34:jar:1.0-SNAPSHOT: Could not find artifact org.jboss.teiid.connectors:connector-salesforce:rar:9.0.0.Final in thirdparty-uploads (https://repository.jboss.org/nexus/content/repositories/thirdparty-uploads/) -> [Help 1]

After removing the dependencies block in the ...\connector-salesforce-34\pom.xml maven works, but it seems to create an invalid adapter.
