Use maven-publish plugin to publish many artifacts from one build file.
Trying to deploy with a gradle build turned out to duplicate too much logic (dependencies, for example) from the soapui maven project.
Since I found how to properly deploy from maven pom without hard-coding values in pom.xml, might as well stay with maven as it is the tool chosen by soapui.
Define repositories to download from and deploy to, configurable via system properties so a build job from a continuous integration server (e.g. jenkins) can publish the projects artifacts.
