Description

The easiest way to reproduce is to change the definition of `Immutable`.

 Change the line:

@TupleConstructor(defaults = false)

to:

@TupleConstructor(defaultsMode = DefaultsMode.OFF)

The first error is to do with stub generation:

subprojects/groovy-macro/build/tmp/compileGroovy/groovy-java-stubs/org/codehaus/groovy/macro/matcher/MatchingConstraints.java:3: error: incompatible types: String cannot be converted to DefaultsMode
@groovy.transform.CompileStatic() @groovy.transform.ToString(includeSuperProperties=true, cache=true) @groovy.transform.EqualsAndHashCode(cache=true) @groovy.transform.ImmutableBase() @groovy.transform.Final() @groovy.transform.ImmutableOptions(knownImmutableClasses={org.codehaus.groovy.macro.matcher.internal.ConstraintPredicate.class}) @groovy.transform.PropertyOptions(propertyHandler=groovy.transform.options.ImmutablePropertyHandler.class) @groovy.transform.TupleConstructor(defaultsMode="OFF") @groovy.transform.MapConstructor(noArg=true, includeSuperProperties=true, includeFields=true) @groovy.transform.KnownImmutable() public class MatchingConstraints
                                                                                                                                                                                                                                                                                                                                                                        
              ^
1 error
startup failed:
Compilation failed; see the compiler error output for details.

Once that is fixed, the next error surfaces which is once the `compileTestGroovy` task is executed:

General error during instruction selection: Cannot generate bytecode for constant: OFF of type: groovy.transform.DefaultsMode
