the class SmartDexingStep method createDxStepForDxPseudoRule.

/**
   * The step to produce the .dex file will be determined by the file extension of outputPath, much
   * as {@code dx} itself chooses whether to embed the dex inside a jar/zip based on the destination
   * file passed to it.  We also create a ".meta" file that contains information about the
   * compressed and uncompressed size of the dex; this information is useful later, in applications,
   * when unpacking.
