----------------------------------------
Summary: 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
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?
