Eric Milles reassigned GROOVY-11793:
------------------------------------
Assignee: Eric Milles
> Cannot Reference Previously Compiled Constants from Annotations
> ---------------------------------------------------------------
>
> Key: GROOVY-11793
> URL: https://issues.apache.org/jira/browse/GROOVY-11793
> Project: Groovy
> Issue Type: Task
> Components: Compiler
> Affects Versions: 4.0.28
> Environment: Mac OS (latest), Java 17, Groovy 4.0.28
> Reporter: James Daugherty
> Assignee: Eric Milles
> Priority: Major
>
> GROOVY-3278 added support in Groovy 3 to reference String constants defined
> on other classes in annotations. In Groovy 4, this appears to be broken when
> split up across different compilation units.
>
> For example, the following will fail:
>
> {code:java}
> import java.lang.annotation.Documented
> import java.lang.annotation.ElementType
> import java.lang.annotation.Inherited
> import java.lang.annotation.Retention
> import java.lang.annotation.RetentionPolicy
> import java.lang.annotation.Target
> import groovy.transform.CompileStatic
> @CompileStatic
> class OtherExample {
> static final String
> MY_VALUE=com.sun.org.apache.xml.internal.security.c14n.Canonicalizer.ALGO_ID_C14N_OMIT_COMMENTS
> }
> @CompileStatic
> @Target([ElementType.METHOD, ElementType.TYPE])
> @Retention(RetentionPolicy.RUNTIME)
> @Inherited
> @Documented
> @interface MyAnnotation {
> String value() default ""
> }
> @CompileStatic
> class TheProblem {
> String foo
>
> @MyAnnotation(OtherExample.MY_VALUE)
> def myTestMethod() {
> 'yello'
> }
> }
> new TheProblem() {code}
>
>
> with this error:
> {code:java}
> Expected 'OtherExample.getMY_VALUE()' to be an inline constant of type
> java.lang.String in @MyAnnotation{code}
> {code:java}
> Attribute 'value' should have type 'java.lang.String'; but found type
> 'java.lang.Object' in @MyAnnotation {code}
> But if the constant is defined on a class in the same script, it will succeed:
> {code:java}
> import java.lang.annotation.Documented
> import java.lang.annotation.ElementType
> import java.lang.annotation.Inherited
> import java.lang.annotation.Retention
> import java.lang.annotation.RetentionPolicy
> import java.lang.annotation.Target
> import groovy.transform.CompileStatic@CompileStatic
> class AnExample {
> static final String CONST = 'foo'
> }
> @CompileStatic
> class OtherExample {
> static final String MY_VALUE=AnExample.CONST
> }
> @CompileStatic
> @Target([ElementType.METHOD, ElementType.TYPE])
> @Retention(RetentionPolicy.RUNTIME)
> @Inherited
> @Documented
> @interface MyAnnotation {
> String value() default ""
> }
> @CompileStatic
> class TheProblem {
> String foo
>
> @MyAnnotation(OtherExample.MY_VALUE)
> def myTestMethod() {
> 'yello'
> }
> }
> new TheProblem() {code}
> Can the Groovy 3 behavior be restored so that constants can be reassigned &
> then referenced in annotations across code that is compiled in separate
> stages?
