    - #### getSourcepath

          @Input
          @Optional
          @Incubating
          public FileCollection getSourcepath()

      The source path to use for the compilation.

      The source path indicates the location of source files that may be compiled if necessary. It is effectively a complement to the class path, where the classes to be compiled against are in source form. It does not indicate the actual primary source being compiled.

      The source path feature of the Java compiler is rarely needed for modern builds that use dependency management.

      The default value for the source path is `null`, which indicates an empty source path. Note that this is different to the default value for the `-sourcepath` option for `javac`, which is to use the value specified by `-classpath`. If you wish to use any source path, it must be explicitly set.

      Returns:
        the source path
      See Also:
        `setSourcepath(FileCollection)`

    - #### setSourcepath

          @Incubating
          public void setSourcepath(FileCollection sourcepath)

        `sourcepath` - the source path

    - #### getAnnotationProcessorPath

          @Optional
          @Incubating
          @Internal
          @Nullable
          public FileCollection getAnnotationProcessorPath()

      Returns the classpath to use to load annotation processors. This path is also used for annotation processor discovery. The default value is `null`, which means use the compile classpath.
      Returns:
        The annotation processor path, or `null` to use the default.
      Since:
        3.4

    - #### setAnnotationProcessorPath

          @Incubating
          public void setAnnotationProcessorPath(@Nullable
                                                   FileCollection annotationProcessorPath)

      Set the classpath to use to load annotation processors. This path is also used for annotation processor discovery. The value can be `null`, which means use the compile classpath.
      Parameters:
        `annotationProcessorPath` - The annotation processor path, or `null` to use the default.
      Since:
        3.4
