      Used to enable or disable incremental compilation after a failure.

      By default, incremental compilation after a failure is enabled for Java and Groovy. It has no effect for Scala. It has no effect if incremental compilation is not enabled.

      When the Java command line compiler is used, i.e. when a custom java home is passed to forkOptions.javaHome or javac is passed to forkOptions.executable, this optimization is automatically disabled, since the compiler is not invoked via the compiler API.

        7.6

    - #### getSourcepath

          @Optional
          @Nullable
          @IgnoreEmptyDirectories
          @PathSensitive(RELATIVE)
          @InputFiles
          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

          public FileCollection getAnnotationProcessorPath()

      Returns the classpath to use to load annotation processors. This path is also used for annotation processor discovery.
      Returns:
        The annotation processor path, or `null` if annotation processing is disabled.
      Since:
        3.4

    - #### setAnnotationProcessorPath

          public void setAnnotationProcessorPath​(@Nullable
                                                 FileCollection annotationProcessorPath)

      Set the classpath to use to load annotation processors. This path is also used for annotation processor discovery.

        3.4

          @Input
          @Optional
          public Property<java.lang.Integer> getRelease()

      Configures the Java language version for this compile task (`--release` compiler flag).

      If set, it will take precedences over the `AbstractCompile.getSourceCompatibility()` and `AbstractCompile.getTargetCompatibility()` settings.
