Compiler Error When Using zinc #78

Error

When using zinc server for incremental builds Peel does not compile due some problem with org/peelframework/core/cli/command/rsync/package$FolderEntry with the following error message:

how can getCommonSuperclass() do its job if different class symbols get the same bytecode-level internal name: org/peelframework/core/cli/command/rsync/package$FolderEntry

This seems to be a know issue of the Scala compiler.

Reproduce

To reproduce this bug, simply start a zinc server with zinc start followed by mvn compile. The compilation might be started twice to trigger this error.

Fix

To fix this we might do one of the following

  1. use a newer scala compiler (>= 2.11.0) or
  2. move the FolderEntry case class from the package object to a utility module.
