Description

The following annotation definition (defines a meta annotation for Spring Boot integration tests

@Inherited
@Retention(RetentionPolicy.RUNTIME)
@Target(ElementType.TYPE)
@SpringApplicationConfiguration(classes = [Configuration, TestConfiguration])
@WebIntegrationTest(randomPort = true)
@ActiveProfiles('integrationTest')
@TestExecutionListeners(
        listeners = FlywayTestExecutionListener,
        mergeMode = TestExecutionListeners.MergeMode.MERGE_WITH_DEFAULTS)
@interface ApplicationTest {

}

fails compilation with the following error messages:

ApplicationTest.groovy: 33: Annotation @org.springframework.boot.test.SpringApplicationConfiguration is not allowed on element ANNOTATION
 @ line 33, column 1.
   @SpringApplicationConfiguration(classes = [Configuration, TestConfiguration])
   ^

ApplicationTest.groovy: 34: Annotation @org.springframework.boot.test.WebIntegrationTest is not allowed on element ANNOTATION
 @ line 34, column 1.
   @WebIntegrationTest(randomPort = true)
   ^

   ^

ApplicationTest.groovy: 36: Annotation @org.springframework.test.context.TestExecutionListeners is not allowed on element ANNOTATION
 @ line 36, column 1.
   @TestExecutionListeners(
   ^

(I omitted imports for brevity)

All of the annotations have `@Target(ElementType.TYPE)`, which according to the documentation:
/** Class, interface (including annotation type), or enum declaration */

Apparently, the Groovy compiler doesn't know that TYPE is also expected to work on annotations.

This issue prevent a lot of annotations being written in Groovy.
