soapUI maven plugin

Hi, i recently start using the soapUI maven plugin and i found some problem using that. Thats is my scenario:
I have proyects that POSSIBLY have a soapUI test. So i need to know if is posible if the file is not found, the compilation not fail and keep with the normal flow of the compilation. In case that the test file was there, then run the tests and if the tests fails the compilation fails (the normal usage of the plugin).

There is some way to do that? In case that i cant do this, then you can provide me the sources of the plugin to add this behaviour?

Thanks in advance
