Gradle uses some libraries, which use different incompatible versions of
ASM (3 and 4).  For upstream that's not a problem as one copy of ASM is
shaded (bundled with namespace changed).  In Fedora ASM cannot be shaded
as this would be against Fedora policy.  This causes problems as two
versions of ASM end up being on Gradle classpath.
