Eric Milles commented on GROOVY-10585:
--------------------------------------
To apply a transform to only non-interface classes, you can use a config script
like this (or its equivalent):
{code:groovy}
withConfig(configuration) {
source(classValidator: { type -> !type.isInterface() }) {
ast(groovy.transform.AutoFinal)
}
}
{code}
I can check on the use of attributes, which should work as you have noted.

> Key: GROOVY-10585
> URL: https://issues.apache.org/jira/browse/GROOVY-10585
> Project: Groovy
> Issue Type: Bug
> Affects Versions: 4.0.1
> Reporter: V
> Priority: Major
>
> When used with `ASTTransformationCustomizer` (like below) or in a
> configscript (`ast(AutoFinal)`, which I think is also using an
> `ASTTransformationCustomizer`), `@AutoFinal` does not seem to take the
> annotation parameters. Applying it individually seems to be fine. A test case
> to demonstrate this:
> {code:groovy}
> class AnnotationParameterTest {
> private static GroovyShell getLoggerShell() {
> final CompilerConfiguration configuration = new CompilerConfiguration()
> configuration.addCompilationCustomizers(
> new ASTTransformationCustomizer(Log, value: 'logger'),
> new ASTTransformationCustomizer(AutoFinal, enabled: false))
> return new GroovyShell(configuration)
> }
> @Test
> void testAnnotationParameters() {
> getLoggerShell().run('''
> @groovy.transform.AutoFinal(enabled = false) // Removing this line
> would fail the test.
> class Foo {
> void testMutation(int i) {
> i = 1
> logger.severe("i = $i")
> }
> }
> new Foo().testMutation(2)''', 'Test')
> }
> }
> {code}
> If the `AutoFinal` annotation *in the script* is removed, the test will fail.
> In which case, `AutoFinal` is applied, but not with the annotation
> parameters. I added a `Log` AST transformation just to make sure I used the
> right way to apply an AST transformation with annotation parameters.
> Not so related:
> Why do I want `AutoFinal(enabled = false)` via `ASTTransformationCustomizer`?
> I was trying to apply `AutoFinal` on all possible types. However `AutoFinal`
> would throw an exception when applied on an interface. And I was testing
> whether I could use `SourceAwareCustomizer` to disable `AutoFinal` for
> interfaces.
