Please see the release announcement for Alpha2 - http://teiid.blogspot.com/2017/07/teiid-1000alpha2-released.html

An important change that is underway is the direct usage of Maven Central for our main artifacts and changing our groupId to org.teiid instead of org.jboss.teiid - https://issues.jboss.org/browse/TEIID-4924

Thanks,

The Teiid Team
