Improve "Ineffective @Order annotation" discovery issue by mentioning meta-annotations #4713
Description
The commit 786de29#diff-4b290a2104fbe0c8f688dfe991a5b5c668f62c6a561abb608421953fd8d5edfe introduced a warning about use of @Order without an orderer.
(1) [INFO] Ineffective @Order annotation on class 'com.example.OrderTest'. It will not be applied because ClassOrderer.OrderAnnotation is not in use.
Source: ClassSource [className = 'com.example.OrderTest', filePosition = null]
at com.example.OrderTest.<no-method>(SourceFile:0)
I do understand the problem, but the information does not help: in my case, a meta-annotation was annotated with @Order and I had to use debug mode to finally find this was due to a meta annotation.
The annotation was annotated like this:
@Retention(RetentionPolicy.RUNTIME)
@Order(1)
public @interface ComposedAnnotation {
}And the test:
@ComposedAnnotation
public class OrderTest {
@Test
void test() {
assertTrue(true);
}
}This result in the following warnings:

Could it be possible to add more details in those warnings?
