IntelliJ not recognizing typescript named module declarations - intellij-idea

Question

I have a situation where my module names need to be in a certain format. Typescript is fine when I do this:
// knockout interfaces, this is knockout.d.ts
declare var ko: KnockoutStatic;
declare module "core!lib/knockout" {
export = ko;
}
And then in my file that uses it:
import ko = require('core!lib/knockout');
IntelliJ doesn't like it though. It says "cannot find external module 'core!lib/knockout'. I'm using the latest stable version (14.1) and this happens with the in-built 1.4 compiler and a custom one.
I guess this may be a Jetbrains bug?

Answer 1

If you add this to the file with the import statement the error will probably go away
/// <reference path="test.ts" />
The real problem I think is that the configuration isn't fully correct. Is the config root correct or are you maybe using version control?
Relevant bits from the link:
From the Scope drop-down list, choose the scope to apply the compiler in. The available options are: – Project Files: all the files within the project content roots (see Content Root and Configuring Content Roots).
– Project Production Files: all the files within the project content roots excluding test sources.
– Project Test Files: all the files within the project test source roots.
– Open Files: all the files that are currently opened in the editor.
VCS Scopes: these scopes are only available if your project is under version control.
– Changed Files: all changed files, that is, all files associated with all existing changelists.
– Default: all the files associated with the changelist
