Broken Example

[bsj0006]

The context

Trying to run the examples for the first time

The bug

Running ./gradlew :example:local-grpc-server:bootRun gives a ClassNotFoundException for HealthEndpointAutoConfiguration during startup. The application exits after throwing the exception.

Stacktrace and logs

Stacktrace is produced before application exits
