When Maven needs to download artifacts from a remote repository, it logs the progress of the download. This can lead to a lot of noise in the output. Luckily, we can suppress the logging of the download progress. Since Maven 3.6.1. we can use the command-line option --no-transfer-progress to disable the logging of the download progress. There is also a short version of the option: -ntp.

In a previous blog post we learned about the default input sources that are used by Helidon SE. The list of input sources is different based on which artifacts are on the classpath of our application. When we write tests for code in our application that uses the default configuration created by Config.create() we must take into account that different input sources are used. Also here it is based on the artifacts that are on the classpath. That means that different files with configuration data are loaded, eg. a file application-test.conf when we have the artifact helidon-config-hocon and a file application-test.yml if the artifact helidon-config-yaml is on the classpath.
