I'm using the professional version of Teamcity 7.0.3 (build 21424) to build Maven project. The particular project is configured as follows: "clean install" with some additional xml processing settings. See image for further details. Anyway, when the build is done - no matter if it was successful or not - there are no jars in the tab "Artifacts". There are just some files created by Teamcity itself, for instance build.style.properties.gz.
ps:your tools are great
