Lib with widgetset


I have a bunch of custom widgets (with custom client side implementations) and today I separated them out into a standalone, eclipse java project so that I can access them through multiple projects easily.

However, after doing that and making a jar file and referencing it in the main vaadin app project I ran into a problem. The widgetset builder wasn’t building my widgets from the jar anymore. I double checked to see whether the jar had the right gwt xml file and was built properly. Verbose compilation showed that my jar wasn’t being considered for any widgetset implementations. I find this strange. If I make any manual changes to the applicaitons widgetset definition by adding an entry (that I know is correct), the compiler deletes that entry. Is there any solution to this problem?


You are most likely missing the required manifest from the add-on jars. Have a look at
