It seems the cssbox dependencies haven't been updated.
Edit loadui-project-2.0.0\loadui-cssbox-browser\pom.xml
Maybe not the best way of doing it, but it works now. Obviously you'll have to change the path!
<dependency>
<groupId>cssbox</groupId>
<artifactId>cssbox</artifactId>
<version>3.4</version>
<scope>system</scope>
<systemPath>D:/eclipse/workspaces/java/loadui-project-2.0.0/loadui-cssbox-browser/src/main/lib/CSSBox.jar</systemPath>
</dependency>
<dependency>
<groupId>cssbox</groupId>
<artifactId>jStyleParser</artifactId>
