Same problem as mentioned by others, Version 2.2.0:
ArtifactDescriptorException: Failed to read artifact descriptor for org.vaadin.addons:googleanalyticstracker:jar:2.2.0: UnresolvableModelException: Failure to find org.vaadin.addons:googleanalyticstracker-addon:pom:2.2.0 in http://maven.vaadin.com/vaadin-addons was cached in the local repository, resolution will not be reattempted until the update interval of vaadin-addons has elapsed or updates are forced pom.xml /Swisscreate-20150203 line 1 Maven Dependency Problem
2.1.0 was good so far but I wanted to use events.
