flowarg/flowupdater

The free and open source solution to update Minecraft.

FlowUpdater

Check the Wiki to know how to use FlowUpdater and more information. Currently, all the documentation (only on GitHub, the documentation in the code is up-to-date) isn't up-to-date because I don't have the time currently to make the tutorial.

Legal and fork notices ⚠️

The CurseForge integration works with an API Key which is mine at the moment. You CAN'T use this key for other purposes outside FlowUpdater. If you wish to fork this project, you HAVE TO use your own API Key.

Usage

Vanilla

First, create a new VanillaVersion, specify arguments. Then build the version :

VanillaVersion version = new VanillaVersionBuilder().withName("1.15.2").build();

NOTE : Builders are all static classes except ForgeVersionBuilder.

You have to put the version you want as parameter, you can set a snapshot (you must set the withSnapshot parameter to true) if you want or latest. The most of FlowUpdater objects are buildable: Build a new UpdaterOptions object: I'm not enabling the re-extracting of natives at each update (withReExtractNatives(true)) because FlowUpdater know which natives must be extracted.

UpdaterOptions options = new UpdaterOptionsBuilder().build();

Note that currently UpdaterOptions is useless unless you want to use a custom ExternalFileDeleter or you want to disable the silent reading.

Then, instantiate a new FlowUpdater with FlowUpdaterBuilder#withXArguments#withAnotherArgument#build. Check the code/JavaDoc for more information.

FlowUpdater updater = new FlowUpdaterBuilder().withVanillaVersion(version).withUpdaterOptions(options).withLogger(someCustomLogger).build();

Don't forget to add a progress callback if you want to make a progress bar!

Finally, call the update function :

updater.update(Paths.get("your/path/"));

Forge

(You need to setup a vanilla updater !)

First, in your vanilla version builder, change the version type to VersionType.FORGE. Next, make a List of Mod objects (except if you have no mods to install).

List<Mod> mods = new ArrayList<>();
mods.add(new Mod("OneMod.jar", "sha1ofmod", 85120, "https://link/of/mod.jar"));
mods.add(new Mod("AnotherMod.jar", "sha1ofanothermod", 86120, "https://link/of/another/mod.jar"));

You can also get a list of mods by providing a json link : List<Mod> mods = Mod.getModsFromJson("https://url.com/launcher/mods.json");. A template is available in Mod class.

You can get mods from CurseForge too:

List<CurseFileInfo> modInfos = new ArrayList<>();
// project ID and file ID
modInfos.add(new CurseFileInfo(238222, 2988823));

You can also get a list of curse mods by providing a json link : List<CurseFileInfo> mods = CurseFileInfo.getFilesFromJson("https://url.com/launcher/cursemods.json");.

Then, build a forge version. For example, I will build a NewForgeVersion.

AbstractForgeVersion forgeVersion = new ForgeVersionBuilder(ForgeVersionBuilder.ForgeVersionType.NEW)
            .withForgeVersion("31.2.29")
            .withCurseMods(modInfos)
            .withOptiFine(new OptiFineInfo("1.16.3_HD_U_G3")) // installing OptiFine for 1.16.3, false = not a preview
            .withFileDeleter(new ModFileDeleter("jei.jar")) // delete bad mods, don't remove the file jei.jar if it's present in the mods' dir.
            .build();

Finally, set the Forge version corresponding to the wanted Forge version :

.withModLoaderVersion(forgeVersion);

That's all!

MCP

(You need to setup a vanilla updater !) In your vanilla version builder, change the version type to VersionType.MCP. Finally, set to vanilla version builder a MCP version :

.withMCP(new MCP("clientURL", "clientSha1", 25008229));

If you set an empty/null string in url and sha1 and 0 in size, the updater will use the default minecraft jar. Example on client-only mcp downloading :

.withMCP(new MCP("https://mighya.eu/resources/Client.jar", "f2c219e485831af2bae9464eebbe4765128c6ad6", 23005862));

You can get an MCP object instance by providing a json link too : .withMCP("https://url.com/launcher/mcp.json");. Nothing else to add :).

Fabric

(You need to setup a vanilla updater !)

First, in your vanilla version builder, change the version type to VersionType.FABRIC. Next, make a List of Mod objects like for a ForgeVersion.

Then, build a Fabric version.

FabricVersion fabricVersion = new FabricVersionBuilder()
            .withFabricVersion("0.10.8")
            .withCurseMods(modInfos)
            .withMods(mods)
            .withFileDeleter(new ModFileDeleter("sodium.jar")) // delete bad mods ; but it won't remove the file sodium.jar if it's present in the mods' dir.
            .build();

Finally, set the Fabric version corresponding to the wanted Fabric version :

.withModLoaderVersion(fabricVersion);

That's all!

External Files

With FlowUpdater, you can download other files in your update dir! In your FlowUpdaterBuilder, precise an array list of ExternalFile (can be got by ExternalFile#getExternalFilesFromJson).

About json files...

All json files can be generated by the FlowUpdaterJsonCreator !

Post executions

With FlowUpdater, you can execute some actions after update, like patch a file, kill a process, launch a process, review a config etc... In your FlowUpdaterBuilder, precise a list of Runnable.

And all it's done !

flowupdater's Issues

No progress callback for Forge download

Hi Flow,
I'm using your library to create a Minecraft launcher with Forge. I implemented the update method for FlowUpdater progress callback to display download step in my UI. It works like a charm while downloading vanilla minecraft.
But as soon as it starts to download Forge / mods, there is not possibility to keep track of the download progress.

Is it a missing feature ? Or is it me who missed something ?

BUG : Impossible de démarrer le jeu avec mc forge 1.12.2

Bonjour/Bonsoir,

Quand je démarre le téléchargement des fichiers du jeu, tout semble fonctionner (les assets, libs, natives et le client.jar sont bien mis) mais lorsque l'installation de forge se déroule, non seulement je trouve qu'elle est très rapide mais le jeu ne semble pas être patché et du coup il ne démarre pas car il ne trouve pas la classe net.minecraft.launchwrapper.Launch qui vient de forge.

Voici le code de l'updater :

et voici les logs de l'installateur de forge présent dans le dossier de destination (je précise qu'avec cette même version prise sur internet c'est-à-dire sur le site de mc forge et bien ça fonctionne nickel) :

PS : j'ai essayé de mettre dans le build.gradle la lib jdom pour voir si ça allait changer quelque chose mais nope

PS 2 : Je suis sur ArchLinux avec le Java 8 de Oracle

Curse Forge Token

Hey are you sure its a good idea for you to upload your curse forge api token to a public repository.... thats really not something you should be doing with any sort of api tokens and just asking people nicely to change it when forking is something that i don't think will work out for you it might be better for you to just have it in some sort of configuration along with a guide for users to help them create a token?

Incorrect link generated when an OptiFine version (preview) is provided without the preview_ prefix

Hi flow !
I may have found a bug for preview version of optifine.
Describe the bug
When I try to download the last preview of optifine (OptiFine HD U I2 pre5), I get a FlowUpdaterException. I am award that it might be my fault since the optifine version is filled in a string.

To Reproduce
Steps to reproduce the behavior:

• Create all the needed stuff to download minecraft 1.19.3 with forge 44.1.17.
• When creating the AbstractForgeVersion, add the following line :

.withOptiFine(new OptiFineInfo("1.19.3_HD_U_I2_pre5", true))

• See the exception.

Expected behavior
No exception and a flawless download.

Desktop (please complete the following information):

• OS: Windows 11
• Java 8

Additional context
I had a look at your OptiFineIntegration code, and to me, the jar name is good, so it shouldn't be a name problem

            final String name = preview ?
                    (optiFineVersion.contains("preview_") && optiFineVersion.contains("OptiFine_") ?
                            optiFineVersion + ".jar" :
                            "preview_OptiFine_" + optiFineVersion + ".jar") :
                    "OptiFine_" + optiFineVersion + ".jar";

Also, does it not make more sense to detect if a version is a preview in the OptiFineInfo(name) constructor than having a boolean parameter that you can miss ? Or does the preview version name of optifine vary that much ?

    AuthInfos authInfos = new AuthInfos(username, "token", "uuid");
    ExternalLaunchProfile profile = MinecraftLauncher.createExternalProfile(infos, GameFolder.FLOW_UPDATER_1_19_SUP, authInfos);
    profile.getVmArgs().add(0, "-Xmx" + memory + "M");
    profile.getVmArgs().add(0, "-Xms" + memory + "M");
    ExternalLauncher launcher = new ExternalLauncher(profile);
    Process game = launcher.launch();
}

Additional context
I managed to make my launcher work with minecraft 1.16.5, but now with 1.19.3 it crashs. I am using java 17, might be a reason for the crash ?
Also, I installed forge and optifine manualy, launch them through the official minecraft launcher : everything is working.

BUG : Fabric URL doesn't exist (UnknownHostException)

Describe the bug
When i try to download latest fabric version using FabricVersionBuilder it doesn't download the fabric file.

To Reproduce
Steps to reproduce the behavior:

1. Create a new kotlin project
2. Create new FabricVersion using FabricVersionBuilder

val builder = FabricVersionBuilder()
    .withFabricVersion("0.14.22")
    .build()

3. Create new FlowUpdater using FlowUpdaterBuilder

val updater = FlowUpdater.FlowUpdaterBuilder()
    .withModLoaderVersion(builder)
    .build()

4. Use FlowUpdater#update
5. See error
