When I build with ant my project that uses libgdx, I get a strange error. It says that a class com.google.gwt.dom.client.ImageElement is not found, but it isn't used at all in the code. How can I find what makes this class necessary? Even searching over the whole project doesn't give any results. It says that error is at PixmapTextureAtlas.java:16 (class source), but there is no code that uses that ImageElement class. Adding the library containing com.google.gwt.dom.client.ImageElement class helps, of course, but I'd like to figure out why this class in needed.
Here is the place in ant log that tells of the actual error:
