One common way to improve the speed of the compiler, is to use a specific user.agent during development and only have one locale. According to this question is one way to achieve this to have multiple .gwt.xml files. One for development another for more test/production usage and then difference which to use by supplying the command line option.
I've tried to add another .gwt.xml file called dev.gwt.xml, but the problem is that the GWT facet includes all gwt.xml files and I don't have any way of "disable" the other gwt.xml file. I would like to be able to disable a gwt.xml file so that I can have multiple gwt.xml files in the project to support the use case above. Is it possible to do this? If not - is this something Jetbrains would consider to include in IntelliJ 9?
