How to run soapUI from sources?

Downloaded sources from svn://svn.eviware.com/soapui/trunk/core. From last comment I found out that maven 3 can be used to compile sources and I need to put all sources to main/java. I using IntelliJ IDEA for building project. 'mvn comple' worked fine but i see error in IDEA in class soapui.demo.DemoListener in line 32: testRunner doen't have method getName();
So I excluded this class from compile and launched after that, here log is:
