- - ### Method Detail

    - #### @Override protected boolean excludeFromAntProperties(String fieldName)

    - #### public GroovyCompileOptions fork(Map<String, Object> forkArgs)

      Convenience method to set GroovyForkOptions with named parameter syntax. Calling this method will set `fork` to `true`.

    - #### @InputFile @Incubating @Optional 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.

    - #### @Input public String getEncoding()

      Tells the source encoding. Defaults to `UTF-8`.

    - #### @Input @Incubating public List<String> getFileExtensions()

      Returns the list of acceptable source file extensions. Only takes effect when compiling against Groovy 1.7 or higher. Defaults to `ImmutableList.of("java", "groovy")`.

    - #### public GroovyForkOptions getForkOptions()

      Returns options for running the Groovy compiler in a separate process. These options only take effect if `fork` is set to `true`.

    - #### public Map<String, Boolean> getOptimizationOptions()

      Returns optimization options for the Groovy compiler. Allowed values for an option are `true` and `false`. Only takes effect when compiling against Groovy 1.8 or higher.

      Known options are:

      indy
        Use the invokedynamic bytecode instruction. Requires JDK7 or higher and Groovy 2.0 or higher. Disabled by default.
      int
        Optimize operations on primitive types (e.g. integers). Enabled by default.
      all
        Enable or disable all optimizations. Note that some optimizations might be mutually exclusive.

    - #### 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.

    - #### public boolean isFailOnError()

      Tells whether the compilation task should fail if compile errors occurred. Defaults to `true`.

    - #### public boolean isFork()

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

    - #### @Incubating @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.

    - #### public boolean isKeepStubs()

      Tells whether Java stubs for Groovy classes generated during Java/Groovy joint compilation should be kept after compilation has completed. Useful for joint compilation debugging purposes. Defaults to `false`.

    - #### public boolean isListFiles()

      Tells whether to print which source files are to be compiled. Defaults to `false`.

    - #### public boolean isVerbose()

      Tells whether to turn on verbose output. Defaults to `false`.

    - #### @Override public Map<String, Object> optionMap()

      Internal method.

    - #### @Incubating public void setConfigurationScript(@Nullable File configurationFile)

      Sets the path to the groovy configuration file.

      Sets the source encoding. Defaults to `UTF-8`.

    - #### public void setFailOnError(boolean failOnError)

      Sets whether the compilation task should fail if compile errors occurred. Defaults to `true`.

    - #### @Incubating public void setFileExtensions(List<String> fileExtensions)

      Sets the list of acceptable source file extensions. Only takes effect when compiling against Groovy 1.7 or higher. Defaults to `ImmutableList.of("java", "groovy")`.

    - #### public void setFork(boolean fork)

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

    - #### public void setForkOptions(GroovyForkOptions forkOptions)

      Sets options for running the Groovy compiler in a separate process. These options only take effect if `fork` is set to `true`.

    - #### @Incubating public void setJavaAnnotationProcessing(boolean javaAnnotationProcessing)

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

    - #### public void setKeepStubs(boolean keepStubs)

    - #### public void setListFiles(boolean listFiles)

      Sets whether to print which source files are to be compiled. Defaults to `false`.

    - #### public void setOptimizationOptions(Map<String, Boolean> optimizationOptions)

      Sets optimization options for the Groovy compiler. Allowed values for an option are `true` and `false`. Only takes effect when compiling against Groovy 1.8 or higher.
