<dependency>
<!-- this is needed or IntelliJ gives junit.jar or junit-platform-launcher:1.3.2 not found errors -->
<groupId>org.junit.platform</groupId>
<artifactId>junit-platform-launcher</artifactId>
<scope>test</scope>
</dependency>


The issue here is that IntelliJ is trying to resolve the required artifact itself without using the Maven ‘User settings file’ (settings.xml) as configured into the IDE. It is going direct to Maven Central which is blocked by my employer.

Q.E.D.

ALL WILL BE CLEAR
