Issues and solutions while getting this project to run...

[stepanzel]

Hey, I want to share some issues I bumped into and also the solutions for anyone else who might experience the same.

1. Missing access righs to close the git repo: the correct command to clone it is git clone https://github.com/protomaps/basemaps.git, which I found out coincidentally.
2. On my WSL. JDK 11 was included but Maven requires at least 21, so an update is necessary by using sudo apt install openjdk-25-jdk. Only then Maven succeeded,
3. For some reason downloading the qrank.csv.gz was incredibly slow. Connecting to a VPN in the US made it better, but best results came using a Japanese VPN connection.
4. Final boss so far: "java.lang.OutOfMemoryError: Java heap space". I solved it by adding the paramater -Xmx3g to the java command line, so java -Xmx3g -jar target/*-with-deps.jar --download --force --area=monaco

Looks like I managed to create the tile files! Unfortunately, I didn't get the server to run yet, because I'm stuck at "nvm use". Will keep you posted...

Edit: Strike that, I just extracted the pmtiles file directly out of the WSL directory structure, which should be good enough haha.
