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.
First look at an example where we do not disable the logging of the download progress. In the output, we see (a lot of) messages showing which artifacts are downloaded and the progress.
$ mvn package [INFO] Scanning for projects...

We remove the downloaded dependencies from our local repository and run the same Maven command again, but now we add the command-line option --no-transfer-progress (or the short version -ntp).
We no longer have the downloading progress messages in our output:
$ mvn --no-transfer-progress package [INFO] Scanning for projects... [INFO] [INFO] --------------------------< com.example:demo >-------------------------- [INFO] Building demo 0.0.1-SNAPSHOT [INFO] from pom.xml [INFO] --------------------------------[ jar ]--------------------------------- [INFO] ...
Instead of adding this option each time we run Maven, we can add it to the file .mvn/maven.config in our project:
--no-transfer-progress
Alternatively, since Maven 3.9.0, we can add the option to the environment variable MAVEN_ARGS.
$ export MAVEN_ARGS=-ntp $ mvn package [INFO] Scanning for projects... [INFO] ...
Written with Maven 3.9.9.
