      • DEFAULT

        public static final CompilerConfiguration DEFAULT
        A convenience for getting a default configuration. Do not modify it! See CompilerConfiguration(Properties) for an example on how to make a suitable copy to modify. But if you're really starting from a default context, then you probably just want new CompilerConfiguration().

    • Constructor Detail

      • CompilerConfiguration

        public CompilerConfiguration​(CompilerConfiguration configuration)
        Copy constructor. Use this if you have a mostly correct configuration for your compilation but you want to make a some changes programmatically. An important reason to prefer this approach is that your code will most likely be forward compatible with future changes to this configuration API.

        An example of this copy constructor at work: 

         // In all likelihood there is already a configuration in your code's context
 // for you to copy, but for the sake of this example we'll use the global default.
 CompilerConfiguration myConfiguration = new CompilerConfiguration(CompilerConfiguration.DEFAULT);
 myConfiguration.setDebug(true);
        Parameters:
        configuration - The configuration to copy.

      • CompilerConfiguration

        public CompilerConfiguration​(Properties configuration)
                      throws ConfigurationException
        Sets the configuration flags/settings according to values from the supplied Properties instance or if not found, supplying a default value. Note that unlike CompilerConfiguration(), the "defaults" here do not in general include checking the settings in System.getProperties(). If you want to set a few flags but keep Groovy's default configuration behavior then be sure to make your settings in a Properties object that is backed by System.getProperties() (which is done using this constructor). That might be done like this: 
         Properties myProperties = new Properties(System.getProperties());
 myProperties.setProperty("groovy.output.debug", "true");
 myConfiguration = new CompilerConfiguration(myProperties);
        And you also have to contend with a possible SecurityException when getting the system properties (See System.getProperties()). A safer approach would be to copy a default CompilerConfiguration and make your changes there using the setter: 
         // In all likelihood there is already a configuration for you to copy,
 // but for the sake of this example we'll use the global default.
 CompilerConfiguration myConfiguration = new CompilerConfiguration(CompilerConfiguration.DEFAULT);
 myConfiguration.setDebug(true);

      • setDisabledGlobalASTTransformations

        public void setDisabledGlobalASTTransformations​(Set<String> disabledGlobalASTTransformations)
        Disables the specified global AST transformations. In order to avoid class loading side effects, it is not recommended to use MyASTTransformation.class.getName() but instead directly use the class name as a string. Disabled AST transformations only apply to automatically loaded global AST transformations, that is to say transformations defined in a META-INF/services/org.codehaus.groovy.transform.ASTTransformation file. If you explicitly add a global AST transformation in your compilation process, for example using the ASTTransformationCustomizer or using a CompilationUnit.PrimaryClassNodeOperation, then nothing will prevent the transformation from being loaded.
        Parameters:
        disabledGlobalASTTransformations - a set of fully qualified class names of global AST transformations which should not be loaded.
