Vaadin 7.7.0 - vaadin-maven-plugin - ignore configuration "theme"

We are using vaadin 7.6.8 without problems (using maven).
In v7.7.0 if we try to compile with maven, we had a problem with theme compilation.
It is like the vaadin-maven-plugin is ignoring the configuration parameter call “theme”.
like: control-theme

This parameter is not longer available in vaadin 7.7.0? Or there is a bug in this version?

Without this option, the compiler tries to compile “themes/.svn” directory
