Crashlytics doesn't update android version code in IntelliJ

I am using Crashlytics plugin version 1.8.0 and IntelliJ CE 13.1.4 on OSX 10.9.4.

I am also using Scala and using build system sbt

externally instead of IntelliJ Make

.

The file crashlytics-build.properties

only updates the latest version code and name from AndroidManifest.xml when IntelliJ starts / restarts.

I suspect that the normal build process for Java runs the Crashlytics plugin to do this, but I'm not sure where or how it looks - is this something that could be replicated and pasted into my own sbt build script?

Otherwise, it is easy to accidentally submit a new assembly using the old version information.
