Configuring ZoneAlarm for usage with Apache Maven

When I was first attempting to install a Maven Project I received this error-message:

It seemed that my beloved free firewall Zonealarm was "protecting" me from the Maven-Repository. Until then I solved issues alike by unblocking the certain program in the menu

Firewall → Application Control → Programme geschützt

Maven does not have its own executable, but is Java-based. All entries labelled Java or similar where unblocked already. Why maven still gets blocked remains a myth to me. There is a workaround, though. You need to add the targeted repository as a safe zone. Here are a few screenshots (Please excuse my german client):

Step 1: Open the tab "Firewall" and select "Zonen anzeigen"

Step 2: Click "Hinzufügen >>", then "Host/Site" to add new zone

Step 3: Enter Maven-Repository Domain ("repo.maven.apache.org") enter a description and hit "Nachschlagen" to look up the Domain-IP. Press "Ok" and once again try to install your project. Maven should be able to download the required libraries now.
