For development purposes you could try the following in your .gwt.xml file
<set-configuration-property name="CssResource.obfuscationPrefix" value="empty"
/>
<set-configuration-property name="UiBinder.useSafeHtmlTemplates" value="false"/>
You many or may not be able to get away with the first setting depending on
how you structured your css. In our project we tried to minimize the amount
of code generation. We have about 250 uibinder files and 300,000 lines of
code. For client bundles, we have very significant sharing of CSS by
composing multiple standard CSS classes e.g.
<ui:with field='ocs' type='com.ocs.client.ui.OcsResource' />
addStyleNames="{ocs.css.btnBlueWithCursor} {ocs.css.marginLeft2u}"
Our RPC is built on a custom code generator that generates JSO based classes
from java command / data objects. The nice thing about this approach is the
code size is very small and
we only rely on the browser JSON serialization so it is very fast. The downside
is that you can't share logic on the client/server.
However, we are looking at migrating to JsInterop which will allow code sharing
as well.
The end result is that our app takes about 80 seconds to do a cold compile for
1 permutation and about 2/3 seconds on a typical SDM refresh.
The obfuscated size of minified bundle is 2.6 MB uncompressed and around 1MB
gzipped.
