Sorry if I was unclear. This needs to be in both "dependencies" and
"export_dependent_settings"

[cjhopman, 2012/09/07 23:03:23]

I believe that this should only be in dependencies. If the settings are
exported, then a target that depends on net would end up compiling the generated
.java file into its .jar and we would have duplicate definitions. Instead, by
just having it in dependencies, the generated java file will be included in the
net_java jar, and then dependents of net_java will have access to it through the
jar.
