Why is a managed Maven dependency missing from compilation?
KitForma editorial guide. An entry in dependencyManagement is a version policy, not a request to put a library on this module’s classpath. This often surfaces when a parent knows a JSON library but its child imports unavailable classes.
Step-by-step guidance
An entry in dependencyManagement is a version policy, not a request to put a library on this module’s classpath. This often surfaces when a parent knows a JSON library but its child imports unavailable classes.
Add that library under the child’s dependencies; keep its version in the parent policy. Inspect
mvn help:effective-pom and mvn dependency:tree from the failing module, not only the aggregator. Confirm the artifact and scope.
Compile the smallest class needing it. Do not copy every managed dependency into every module: that hides ownership and increases runtime exposure. Plugin dependencies are another graph; application dependencies cannot fix every plugin error.Sources and verification
