All Ignite artifacts are in Maven Central, there is no designated repo. ignite-spring:1.4.0  is there. ignite-hadoop2-integration module doesn't exist, but there is ignite-hadoop  (and this is the correct name).
It looks like you have some local configuration issue. I would try to completely delete the local repository (~/.m2/repository folder) and ~/.m2/settings.xml file. This will force Maven to build everything from scratch.
