CXF has a bunch of automatic builds configured in the Apache Hudson/Jenkins instance at https://hudson.apache.org/hudson/view/A-F/view/CXF/. There are builds there that trigger automatically on code commits. There are also nightly builds to test on other JDK's as well as other platforms.
CXF also is configured as a build in the Apache Sonar instance at https://analysis.apache.org/dashboard/index/org.apache.cxf:cxf. The Sonar instance runs a variety of quality checks as part of the build.
