# SBT 1.x depends on scalapb-runtime which contains a compiled copy of
# scalapb.proto.  When the compiler plugin is loaded into SBT it may cause a
# conflict. To prevent that, we use a different package name for the generated
# code for the compiler-plugin.  In the past, we used shading for this
# purpose, but this makes it harder to create more protoc plugins that depend
# on compiler-plugin
