IntelliJ 2016.1 Plugin - not found

I have just upgraded to Intellij 2016.1 and now my synthetic android views are not recognised by the UI as the* import is not found. I have rebuilt the project but this has not helped. I have the latest kotlin plugin (1.0.1-release-IJ143-27). Any ideas?

@mbrickman Could you please try to re-import your Gradle project?

Hi @yanex, I’m sorry but I don’t really understand what you are asking me to do here as I don’t have a Gradle project or know how to re-import one. My project was set-up as a Kotlin project. Perhaps Gradle is lurking in the background, but one of the reasons I like IntelliJ is that I don’t have to worry about build systems (I come from a delphi background where things are much simpler that in the JVM world). Could you be more specific?
