JUnit Jupiter 5.12 fails to find tests with Maven Surefire #4341
Description
Upgrading from junit-jupiter-api:5.11.4 and junit-platform-commons:1.11.4 to 5.12.0 and 1.12.0 respectively causes: "TestEngine with ID 'junit-jupiter' failed to discover tests”.
The pom.xml in my project contains;
<dependency>
<groupId>org.junit.jupiter</groupId>
<artifactId>junit-jupiter-api</artifactId>
<scope>test</scope>
</dependency>
<dependency>
<groupId>org.mockito</groupId>
<artifactId>mockito-junit-jupiter</artifactId>
<scope>test</scope>
</dependency>junit-platform-commons is transitive.
mockito-junit-jupiter:5.15.2 is included which brings in mockito-core at the same version.
I include surefire with 5.12.0 engine.

The error is thrown:

Adding junit-platform-engine:1.12.0 to the classpath produces the same outcome but a different cause;
Caused by: org.junit.platform.commons.JUnitException: OutputDirectoryProvider not available; probably due to unaligned versions of the junit-platform-engine and junit-platform-launcher jars on the classpath/module path.

The project is JDK 11 running maven 3.9.9.
My project runs on Jenkins with a renovate GitHub app pulling in updates for PR. All projects with 5.12.0 fail with the same error.
