JUnit tests in Gradle project cannot be run from Eclipse

[PyvesB]

Expected Behavior

In a Gradle project, right clicking on a JUnit 5 test class annotated with @MicronautTestand selecting Run As -> JUnit Test should successfully run the tests inside the IDE.

Actual Behaviour

The JUnit engine fails to run the tests and the following error message is surfaced in Eclipse:

org.junit.jupiter.engine.execution.ConditionEvaluationException: Failed to evaluate condition [io.micronaut.test.extensions.junit5.MicronautJunit5Extension]: @MicronautTest used on test but no bean definition for the test present. This error indicates a misconfigured build or IDE. Please add the 'micronaut-inject-java' annotation processor to your test processor path (for Java this is the testAnnotationProcessor scope, for Kotlin kaptTest and for Groovy testCompile). See the documentation for reference: https://micronaut-projects.github.io/micronaut-test/latest/guide/

Steps To Reproduce

1. Download and install Eclipse IDE for Java Developers.
2. Check out one of the examples: https://github.com/micronaut-projects/micronaut-examples/tree/master/hello-world-java
3. Follow the official documentation to import the Gradle project into Eclipse: https://docs.micronaut.io/latest/guide/#eclipseSetup
4. In the Package/Project explorer, navigate to HelloControllerTest.java.
5. Right click on the class, select Run As -> JUnit Test.

Note that micronaut-examples uses an outdated version of Micronaut, but I'm able to reproduce with the latest one as well.
