Thanks for reporting and sorry for the inconvinience, both 5.2.0 and 5.2.1 soapui-maven-plugins have been published to maven repo now.
Please fix this. I have the exact same problem with the project pom file for soapui 5.2.1.
http://smartbearsoftware.com/repository/maven2/com/smartbear/soapui/soapui-project/5.2.1 does not exist
<parent>
<groupId>com.smartbear.soapui</groupId>
<artifactId>soapui-project</artifactId>
<version>5.2.1</version>
</parent>
Just to be clear: this is not broken, the maven-plugin version 5.2+ is simply not available.
Maybe the maven plugin is not available, still the repo is broken for the soapui artifacts. We maintain a list of plugins that compile against the soapui extension classes. We can't build for version 5.2.0 and 5.2.1 because of the missing project pom files.
