Trouble following README.md instructions

Hi, continuing this issue and following this comment:

If you would like to have a separate flatpak for Epic Games Launcher, try
https://github.com/plata/phoenicis-app-flatpak-generator.

I barely know anything about programming, but I've been trying to install Epic Games Launcher building a flatpak version of it using this phoenicis-app-flatpak-generator, because that's what I was suggested. So trying to follow the instructions, line by line, this happened:

The first message says that the phoenicis clone is already made (because I already ran that command) but that's not the problem though. The problem is that when I run this command mvn package -DskipTests it gives out this message bash: mvn: comando non trovato which means "command not found" so I don't know if I should run the next command which is cd ..

Please take into account that I don't understand many programming concepts so just tell me what I can do, exactly as I should do it.

NOTE: This is assuming that you are on Ubuntu/Mint. Otherwise, you must adapt the apt commands.

"command not found": you must install maven (sudo apt install maven)

Apart from that, you need flatpak-builder and the flatpak runtime and extensions:

sudo add-apt-repository ppa:alexlarsson/flatpak -y
sudo apt update -q
sudo apt install -y flatpak flatpak-builder
flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo
flatpak -y install flathub org.freedesktop.Platform/x86_64/19.08
flatpak -y install flathub org.freedesktop.Sdk/x86_64/19.08
flatpak -y install flathub org.freedesktop.Sdk.Compat.i386/x86_64/19.08
flatpak -y install flathub org.freedesktop.Sdk.Extension.toolchain-i386/x86_64/19.08
flatpak -y install flathub org.freedesktop.Sdk.Extension.openjdk11/x86_64/19.08
flatpak -y install flathub org.freedesktop.Platform.Compat.i386/x86_64/19.08
flatpak -y install flathub org.freedesktop.Platform.GL32.nvidia-410-73/x86_64/1.4

After that, run the following commands in an empty directory:

git clone https://github.com/PhoenicisOrg/scripts.git
python phoenicis-app-flatpak-generator.py -i scripts/Applications/Games/Epic\ Games\ Launcher/Online/ -o output
cd output
git clone https://github.com/PhoenicisOrg/phoenicis.git
cd phoenicis
mvn package -DskipTests
cd ..
cp phoenicis/phoenicis-dist/target/phoenicis-flatpak.zip .
flatpak-builder build-dir org.phoenicis.epic_games_launcher.yml --force-clean --user --install

Now, you should be able to run

flatpak run org.phoenicis.epic_games_launcher

EDIT: Do not use flatpak-openldap branch (has been merged to master).

Crap, I forgot, sorry, the OS I'm using is Endeless 3.8.3, in this OS what would the apt commands be like?

And also, apart form those apt commands the rest is the same, right?

Sorry for the inconvenience, I'm an idiot when it comes to this kind of stuff 😅

@LeandroStanger I don't know Endless OS. Can you help @Alvareto136?
