what does this error mean?

elect: Could you show also your build.gradle section where you're configuring dependencies and buildscript? Github link would be ok too.

Seems that you're getting

kotlin-reflect:1.0.4

as a transitive dependency of one of your dependencies, and since it would cause problems when used with

kotlin-stdlib:1.1

, the compiler prohibits such dependency graph.

..ok, then I'll go through the dependencies to update them
