I am encountering a fatal build error trying to resolve a reference for recent versions of Google’s
ConstraintLayout library for Android. The most recent stable versions are 2.0.1, 2.0.0, and 1.1.3. I am able to build using 1.1.3 but not for 2.0.+. (But I have to use 2.0.+, since when I reference 1.1.3 in my main project, I get a “missing method” runtime error on a method that is apparently referenced by a different library I include).
Here is a sample project. It’s a clean new project with only a reference to the ConstraintLayout library added. As it stands, it generates 4 build errors “attibute ___ has already been defined”. Seems like possibly a merging issue? Reverting the gradle reference to 1.1.3 causes the errors to go away.
