With a newly set up Maven project I tried deploying the site using mvn site:deploy. The command kept failing with the following error

Embedded error: Error performing commands for file transfer
Exit code: 0 - bash: unzip: command not found

for the longest time. I tried all kinds of funny things although I was 100% certain that I do have unzip in path. I was a bit embarresed when I finally realized that this error message was the result of the command executed over SSH on the remote host (Debian Linux) – the one the site was deployed to.

After that it was a piece of cake. Just had to install unzip on Linux using APT: apt-get install unzip
