Why?

I thought it would be fun to write in Rust. If you wanted a single line of bash to do it, use one of these (requires jq, curl, and wget):

Download latest available (snapshot or release) minecraft server.jar

curl -s $(curl -s "https://launchermeta.mojang.com/mc/game/version_manifest.json" | jq -r ".versions[0].url") | jq -r ".downloads.server.url" | xargs wget

Download latest release minecraft server.jar

curl -s $(curl -s "https://launchermeta.mojang.com/mc/game/version_manifest.json" | jq -r ".latest.release as \$v | .versions[] | select(.id == \$v) | .url") | jq -r ".downloads.server.url" | xargs wget

Download latest snapshot minecraft server.jar

curl -s $(curl -s "https://launchermeta.mojang.com/mc/game/version_manifest.json" | jq -r ".latest.snapshot as \$v | .versions[] | select(.id == \$v) | .url") | jq -r ".downloads.server.url" | xargs wget

Example Scripts

(Windows) Automatically install latest snapshot, then start minecraft server

@echo OFF
@REM if a version file exists, check if it's the latest, otherwise download the server
if exist version.txt (
  goto checkVersion
) else (
  goto download
)

:checkVersion
@REM compare latest version with the one that is installed
mcdl.exe -sp > temp.version.txt
fc /b temp.version.txt version.txt > nul
if errorlevel 1 (
  @REM on different version - install the game
  mcdl.exe -s
  move /y temp.version.txt version.txt > nul
) else (
  @REM on same version delete the temp file
  del temp.version.txt > nul
)
goto server

@REM download the game and update the version
:download
mcdl.exe -s
mcdl.exe -sp > version.txt

@REM start the server
:server
java -Xmx4G -Xms2G -jar server.jar nogui

timeout /t 5
goto server
pause
