Java Grade School tests fail because junit cannot be found

Tests are failing after submitting a solution to Grade School in Java, with errors like:

./src/test/java/SchoolTest.java:1: error: package org.junit does not exist
import static org.junit.Assert.assertEquals;

Since I didn’t submit the tests, only the solution, I can only suspect that the error is on Exercism side, right?

By any chance, does the Grade School page indicate that there has been updates to the exercise? There will be a message at the top of the page if it is, like in this screenshot:

The assertEquals was changed a couple of years ago (see PR #2515). You may need to update the exercise (click on “See what’s changed…” and then “update exercise”).

Ok thanks, updated and not it’s using jupiter instead.
