The following error was showing up when a project relied on backstopper-reusable-tests but also a newer version of org.reflections:reflections than what backstopper was compiled with: NoSuchMethodError: org.reflections.util.ClasspathHelper.forPackage(Ljava/lang/String;[Ljava/lang/ClassLoader;)Ljava/util/Set;.

For example I ran into this when using Kotlin in a Backstopper-powered project because Kotlin was pulling in org.reflections:reflections:0.9.11. Compiling backstopper with the latest org.reflections:reflections version seems to fix the issue.
