# The old artifactId's release history simply stops at 1.21.4 - no 2.x version was ever
# published under org.testcontainers:junit-jupiter. The new artifactId's history starts fresh
# at 2.0.0. This is the real, permanent fork point on Maven Central: "upgrade the version
# number" on your existing <artifactId>junit-jupiter</artifactId> dependency has no 2.x version
# to resolve to - it will stay on 1.21.4 forever, or fail outright for a module whose own
# artifactId was retired rather than just renamed (see 05-legacy-pom-fails-to-resolve-under-2.0.5.txt,
# where this happens to org.testcontainers:postgresql).
#
# This is one rename out of 61: OpenRewrite's own migration recipe documents the full list at
# https://docs.openrewrite.org/recipes/java/testing/testcontainers/testcontainers2dependencies -
# every org.testcontainers:<module> artifact gets a testcontainers-<module> artifactId, same
# groupId, same Maven Central repository. The core artifact, plain org.testcontainers:testcontainers,
# is the one name on the list that did NOT change.
