### Ubuntu install notes without IDE:

# Get our custom mc-unified branch. Contains Minecraft server code.
git clone https://github.com/HumanCompatibleAI/mc-unified
cd mc-unified
git fetch -v
git checkout neel/cavesexperiment

# Building and running the custom Minecraft server plugin.
sudo apt install -y maven
pushd mcplugin
mvn install
popd

# Run server in foreground.
# (Will occupy your shell, maybe consider running in a tmux pane.)
pushd mcserver
java -jar paperclip.jar
popd

# To connect and record trajectories, you will need a
# 1.12.2-compatible client. Buy Minecraft, and
# in the Minecraft Launcher, select and install the 1.12.2 client.

# Now patch your Minecraft client with trajectory-recording mod.
# You can save this anywhere, and can delete after successfully installing.
wget 'minerl.io/downloads/minerl_installer.jar'
java -jar minerl_installer.jar

# Restart the Minecraft Launcher and launch the "forge" Minecraft client.

# Connect to `localhost` in the Minecraft client's multiplayer mode.
# Now you are connected to your custom server!
