    - #### setFork

          public void setFork​(boolean fork)

      Sets whether to run the Groovy compiler in a separate process. Defaults to `true`.

    - #### getConfigurationScript

          @Nullable
          @Optional
          @PathSensitive(NONE)
          @InputFile
          public File getConfigurationScript()

      A Groovy script file that configures the compiler, allowing extensive control over how the code is compiled.

      The script is executed as Groovy code, with the following context:

      - The instance of CompilerConfiguration available as the `configuration` variable.
      - All static members of CompilerCustomizationBuilder pre imported.

      This facilitates the following pattern:

           withConfig(configuration) {
             // use compiler configuration DSL here
           }

      For example, to activate type checking for all Groovy classes…

           import groovy.transform.TypeChecked

           withConfig(configuration) {
               ast(TypeChecked)
           }

      Please see the Groovy compiler customization builder documentation for more information about the compiler configuration DSL.

      This feature is only available if compiling with Groovy 2.1 or later.

    - #### setConfigurationScript

          public void setConfigurationScript​(@Nullable
                                             File configurationFile)

      Sets the path to the groovy configuration file.

        `getConfigurationScript()`

    - #### isJavaAnnotationProcessing

          @Input
          public boolean isJavaAnnotationProcessing()

      Whether the Groovy code should be subject to Java annotation processing.

      Annotation processing of Groovy code works by having annotation processors visit the Java stubs generated by the Groovy compiler in order to support joint compilation of Groovy and Java source.

      When set to `true`, stubs will be unconditionally generated for all Groovy sources, and Java annotations processors will be executed on those stubs.

      When this option is set to `false` (the default), Groovy code will not be subject to annotation processing, but any joint compiled Java code will be. If the compiler argument `"-proc:none"` was specified as part of the Java compile options, the value of this flag will be ignored. No annotation processing will be performed regardless, on Java or Groovy source.

    - #### setJavaAnnotationProcessing

          public void setJavaAnnotationProcessing​(boolean javaAnnotationProcessing)

      Sets whether Java annotation processors should process annotations on stubs. Defaults to `false`.

        6.1

    - #### getForkOptions

          public GroovyForkOptions getForkOptions()

          @Internal
          public File getStubDir()

      Returns the directory where Java stubs for Groovy classes will be stored during Java/Groovy joint compilation. Defaults to `null`, in which case a temporary directory will be used.
