# Proguard lookup program classes before library classes. In R8 this is
# not the behaviour (it used to be) R8 will check library classes before
# program classes. Some apps have duplicate classes in the library and program.
# To make these apps work with R8 simulate program classes before library
# classes by creating a new library jar which have all the provided library
# classes which are not also in program classes.
