4.0.0 org.apache.hadoop hadoop-project 3.2.3 ../../hadoop-project hadoop-client-check-invariants 3.2.3 pom Enforces our invariants for the api and runtime client modules. E.g. that modules have a specific set of transitive dependencies and shaded artifacts only contain classes that are in particular packages. Does the enforcement through the maven-enforcer-plugin and an integration test.
