> 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}

> @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?
