Run this sample to connect to an endpoint that is protected by GCP authentication.

First, get GCP credentials on your machine:

gcloud auth application-default login

Executing this command will save your application credentials to default path which will depend on the type of machine -

• Linux, macOS: $HOME/.config/gcloud/application_default_credentials.json
• Windows: %APPDATA%\gcloud\application_default_credentials.json

Next, update build.gradle to set the following:

	'-Dgoogle.cloud-project=<YOUR_PROJECT_ID>,
	# Optional - if you want to export using gRPC protocol
	'-Dotel.exporter.otlp.protocol=grpc',

Finally, to run the sample from the project root:

./gradlew :examples-otlpmetric:run
