I have a project that worked fine with Idea 15, but with 2016.1 I am getting spurious error flags in one source file. Screenshot below, and if I hover over the error it says "cannot access com.controlj.utility.CJLog". This class is in a JAR file that is a included in the build.gradle for a module called Utilities, which my app module depends on. If I include the same JAR file in the app build.gradle the error goes away but then I get the problem with multiple definitions when DEXing. Even though these errors are flagged, the module builds and runs just fine, both from Idea and the command line using gradlew.
