Hi,
I’m trying to compile a widgetset for vaadin 7.5.7 wihtout using the eclipse plugin. To do that I use the ant script from here: https://vaadin.com/download/misc/build-widgetset.xml
First problem is that the ant script above is not compatible to Vaadin 7.5.7. I have adjust the script to
<?xml version="1.0"?>
<!--
Client-side code is compiled by using GWTCompiler which compiles client-side Java code into
JavaScript. Generated files are located under WebContent/VAADIN/widgetsets/*.
Client-side compilation is required if you create new or modify existing widgets.
You may use either this script or Vaadin Hosted Mode Browser.launch (in Eclipse)
to compile your client-side java code.
By default Vaadin first tries to serve widgetset resources from the file system, if that
fails then files are streamed from vaadin-@version@.jar.
See configure target to adjust this buildfile.

Update based on your project structure, by default this buildfile assumes that you
1. use WebContent under your project's root directory
2. WebContent/WEB-INF/lib/vaadin-@version@.jar exists

4. gwt directory contains extracted GWT distribution

... 139 moreBut I cannot find the GeneratorExt class in any jar file of Vaadin 7.5.7. Anybody knows whats wrong or missing? Is there anywhere a tutorial how I can compile a widgetset for Vaadin 7.5/7.6 “by hand” (means: without using the eclipse plugin)?
Thanks,
Steffen
EDIT
Same result by using following command line call:
java -classpath vaadin-client-compiler-7.5.7.jar:guava-16.0.1.vaadin1.jar:../../../src:gwt-user.jar:vaadin-widgets-7.5.7.jar:ant-1.6.5.jar com.google.gwt.dev.Compiler -war ../../VAADIN/widgetsets com.xyz.vaadin.widgetset.XyzvaadinWidgetset
