It happened with both the make button and when running it (yes, I had removed the "Gradle-aware make" step and replaced it with android:packageDebug from the SBT shell plugin). Sadly, I don't have the error message anymore, and it seemed to work when building from the command-line tool. I suppose I could have kept going like that, but it's very nice to have the proper debugging tools that an IDE provides. :/
