Tapx -yui richtexteditor : yahoo-dom-event-min.js (the file does not exist).

When using the component richtexteditor in   tapx-yui-1.2-SNAPSHOT.jar from 


http://howardlewisship.com/snapshot-repository.,

I get the following error. 
Unable to locate asset 
'classpath:com/howardlewisship/tapx/yui_2_8_0r4/build/yahoo-dom-event/yahoo-dom-event-min.js'
 (the file does not exist).

In Eclipse, I have found that yahoo-dom-event-min.js is in  
tapx-yui-1.2-SANAPSHOT.jar. But 
somehow the folder com/howardlewisship/tapx/yui_2_8_0r4/build/yahoo-dom-event/ 
is not in  the classpath. 

I get the same error if I  a download the source from 
https://github.com/hlship/tapx/
and do a 'gradle install'. 

Thanks in advance for any assistance!
