QuarkusIntegrationTests fails while testing jar

[javiertoja]

Describe the bug

I'm not completely sure if this is a bug or I'm should do some additional setup.

While trying to complete a maven build to test the QuarkusIntegrationTests annotation having only one test with this annotation, the build fails with the error java.lang.IllegalStateException: Unable to locate the artifact metadata file created that must be created by Quarkus in order to run tests annotated with '@QuarkusIntegrationTest'.

Expected behavior

I expected that executing mvn -B verify --file quarkus/integration-test/pom.xml the test will pass without errors

Actual behavior

The build fails with the error java.lang.IllegalStateException: Unable to locate the artifact metadata file created that must be created by Quarkus in order to run tests annotated with '@QuarkusIntegrationTest'.

To Reproduce

Link to a small reproducer (preferably a Maven project if the issue is not Gradle-specific).
Project to reproduce the issue

Steps to reproduce the behavior:

1. Setup java 16 and maven
2. Execute mvn -B verify --file quarkus/integration-test/pom.xml

## Environment (please complete the following information):

### Output of `uname -a` or `ver`

### GraalVM version (if different from Java)

### Quarkus version or git rev

Additional context

If mixed with the sample GreetingsResource unit test, the execution of the Integration tests fails because while trying to start the application with java -jar, the process finds the testing port occupied by the execution of the unit test, which stills holds the port.

Error reproduced with a github action build.

Tests annotated with @QuarkusIntegrationTest should be run by the maven-failsafe-plugin in the verify phase, not by maven-surefire-plugin in the test phase (same as the @NativeImageTest).

I have added a note in the documentation to make that more clear
