You might actually don't need the @CompileStatic annotation in this
example. Here is what the bytecode decompiled to the Java class looks like
(an example without static compilation enabled):
//
// Source code recreated from a .class file by IntelliJ IDEA
// (powered by FernFlower decompiler)
//
public @interface SomeAnnotation {
Class<?>[] someAttribute() default {};
}
This is exactly what you could expect from using static compilation.
However, if your annotation has some other methods where using the static
compilation useful, you can annotate problematic method
with @CompileDynamic, something like this:
import groovy.transform.CompileDynamic
import groovy.transform.CompileStatic
@CompileStatic
@interface SomeAnnotation {
@CompileDynamic
Class<?>[] someAttribute() default []
}
