Added a file parameter for file inclusion by tkhduracell · Pull Request #74 · luontola/retrolambda

Background: Incremental build fails in larger projects, due to the command line reaching max allowed characters.

Will create a corresponding update in the Gradle plugin.

  retrolambda.includedFile
      A file listing the files to process (one file per line), instead of processing all files.
      This is useful for a build tool to support incremental compilation.
