C:\Users\Public\Cloudwatch jar>java -jar target/cloudwatch_exporter-0.10.0-jar-with-dependencies.jar 9106 example.yml
Error: Could not find or load main class io.prometheus.cloudwatch.WebServer
Caused by: java.lang.ClassNotFoundException: io.prometheus.cloudwatch.WebServer

Im a little lost here and dont know why this is failing...

Start with pom.xml and the target/cloudwatch_exporter-0.10.0-jar-with-dependencies.jar named in the report; inspect whether io.prometheus.cloudwatch.WebServer is present and how the application entry point is configured. Compare the documented or project-provided launch command with the Windows command shown, then verify that the exporter starts with example.yml and port 9106.
