# End-to-end integration test: builds the whole reactor (the plugin + the vendored example
# modules) with a single `./mvnw install`, proving the generated sources compile and run
# against DGS + Spring Boot. The plugin builds first in reactor order, so the examples
# exercise the just-built plugin, and the client-introspection module starts its own DGS
# server for live introspection. Spring Boot never enters the plugin's own build (enforced
# by the maven-enforcer ban-spring-boot rule that runs during the plugin module build).
