GROOVY-6764: Problem Referring To Statically Imported Constants
----
> Problem Referring To Statically Imported Constants
> --------------------------------------------------
>
> Key: GROOVY-6764
> URL: https://issues.apache.org/jira/browse/GROOVY-6764
> Project: Groovy
> Issue Type: Bug
> Affects Versions: 2.1.9, 2.4.0-rc-1
> Reporter: Jeff Brown
> Attachments: constantsquestion.zip
>
>
> It appears that if a class implements an interface which declares constants,
> Groovy code which statically imports the constant from the class (not the
> interface) doesn't work. I think this is supposed to work. It does work
> from Java. See the attached app in constantsquestion.zip which includes the
> following code. Extract the .zip and run "./gradlew test" to see that the
> Java test passes and the Groovy test fails.
> {code:borderStyle=solid|title=src/main/java/com/demo/Constants.java}
> package com.demo;
> public interface Constants {
> int ANSWER = 42;
> }
> {code}
> {code:borderStyle=solid|title=src/main/java/com/demo/Helper.java}
> package com.demo;
> public class Helper implements Constants {
> }
> {code}
> {code:borderStyle=solid|title=test/java/com/demo/JavaHelperTests.java}
> package com.demo;
> import org.junit.Test;
> import org.junit.runner.RunWith;
> import org.junit.runners.JUnit4;
> import static org.junit.Assert.assertEquals;
> import static com.demo.Helper.ANSWER;
> @RunWith(JUnit4.class)
> public class JavaHelperTests {
> @Test
> public void testAccessingConstant() {
> // this test passes...
> assertEquals(42, ANSWER);
> }
> }
> {code}
> {code:borderStyle=solid|title=test/groovy/com/demo/GroovyHelperSpec.groovy}
> package com.demo
> import spock.lang.Specification
> import static com.demo.Helper.ANSWER
> class GroovyHelperSpec extends Specification {
> void 'test referring to statically imported constant'() {
> // this test fails...
> expect:
> 42 == ANSWER
> }
> }
> {code}
> The error message from the Groovy spec is:
> {noformat}
> groovy.lang.MissingPropertyException: No such property: ANSWER for class:
> com.demo.GroovyHelperSpec
> at com.demo.GroovyHelperSpec.test referring to statically imported
> constant(GroovyHelperSpec.groovy:10)
> {noformat}
> Note that everything works fine from Groovy if the constant is imported from
> the interface instead of from the class which implements the interface.
> Is this a bug?
