Add Gradle and Maven version parameters to Java (#263)

* Refactor java feature tests grep syntax

The grep with pipe syntax was creating problems with the check helper

Change them in favour of process substitution syntax

* Fix java feature tests about java version

Java 18 is not available anymore in SDKMAN

Some tests asserts were generating false positives

* Add Gradle and Maven version parameters to Java
