Since bottom-up to top-down graph traversal switch in Buck, only
first order dependencies are built per default. This leads to a
problem when gerrit is built without --deep option (per default).
Move gwt-dev dependencies to gwt_binary() rules.
The correct fix for this issue would be to model the GWT compiler
as a tool, and ensure that its transitive deps are added as first
order deps of the gwt_binary() rules: [1]. Put this workaround for
now in tree and fix build breakages. We can always improve things
when Buck supports that new model.
Test plan:
* buck clean
* change one of GWT classes
* buck build //gerrit-gwtui:ui_opt
* buck build api_install
