Query on dependency versioning

[DavidGerald-Milligan]

When I add maven dependencies on org.junit.jupiter:junit-jupiter-api:jar:5.11.3 and org.junit.jupiter:junit-jupiter-engine:jar:5:11.3 and invoke assertThrows I get java.lang.NoClassDefFoundError: org/junit/platform/commons/util/UnrecoverableExceptions

UnrecoverableExceptions is present in org.junit.platform:junit-platform-commons:5.11.3 and mvnrepository.com lists this version as a dependency.

Yet when I query the dependency tree I get

[INFO] - org.junit.jupiter:junit-jupiter-api:jar:5.11.3:test
[INFO] +- org.opentest4j:opentest4j:jar:1.3.0:test
[INFO] +- org.junit.platform:junit-platform-commons:jar:1.6.2:test
[INFO] - org.apiguardian:apiguardian-api:jar:1.1.2:test

org.junit.platform:junit-platform-commons:jar:1.6.2 does not include UnrecoverableExceptions

Updating my dependencies to org.junit.jupiter:junit-jupiter:jar:5.11.3 and org.junit.jupiter:junit-jupiter-api:jar:5.11.3 resolves the issue but I am trying to understand why we have the difference in the tree and the documented dependencies.

Unless you’re using Spring Boot which defines its own way of managing dependencies, it is recommended to use the JUnit Platform BOM to align the versions of all JUnit 5 artifacts.

https://junit.org/junit5/docs/current/user-guide/#running-tests-build-maven-bom

[...] why we have the difference in the tree and the documented dependencies.

Perhaps some other dependency already refers to platform-commons and "locks the version to be used to 1.6.2"?

@DavidGerald-Milligan you can use mvn dependency:tree with -Dverbose to get a bit more info about the way maven up/downgrades dependencies.
