A simple program that downloads and updates modpacks automatically. It was written to work directly as a pre-launch command for MultiMC and features
- Delta updates (only download mods that changed).
- Easy creation of modpacks (just a text file with names, versions, download links and checksums)
- No need for a huge amount of webspace or traffic!
You can find an example modpack in the folder "ExamplePack".
Basically add the Updater.jar into the instance zip in the minecraft folder
and add this line to the instance.cfg file
PreLaunchCommand=java -jar "$INST_MC_DIR/Updater.jar" "Link to modpack.cfg file"
The config file on your server is a csv with the following values:
Name,Version,Download-URL,Type,checksum,flags
Where Type is either "mod", "config" or "resources":
"config" and "resources" are both zip files.
and get extracted into the root folder of your Minecraft instance.
Checksum is optional and if present a sha256 sum of the file.
Flags is a semicolon(;) separated list of flags.
Currently supported are server_only, client_only and force_overwrite
Install Scala and SBT, then run sbt assembly. This will produce a standalone jar.
For development you can use IntelliJ Idea with the scala plugin, which has native support for sbt
