Class ServerJarInstaller

Namespace
McServerLauncher.Services
Assembly
McServerLauncher.dll

Puts the right server files on disk for a server type, whichever way that type is obtained.

public class ServerJarInstaller
Inheritance
ServerJarInstaller
Inherited Members

Remarks

The ways differ more than they look: Vanilla, Paper and Purpur are a jar to download, Fabric is a jar the loader builds for a version pair, and Forge and NeoForge run an installer that leaves no runnable jar at all and must be launched through an args file instead.

This chain used to exist twice, spelled out inline in the create-server dialog and again in the change-loader dialog. Every type added had to be added to both, and a type present in one and missing from the other fell through to "download the vanilla jar" without complaining — you would pick Purpur and quietly get Vanilla.

Constructors

ServerJarInstaller(MinecraftVersionService?, ModLoaderService?, PaperService?, PurpurService?, ServerCreationService?) 

public ServerJarInstaller(MinecraftVersionService? versions = null, ModLoaderService? mods = null, PaperService? paper = null, PurpurService? purpur = null, ServerCreationService? creation = null)

Parameters

versions MinecraftVersionService
mods ModLoaderService
paper PaperService
purpur PurpurService
creation ServerCreationService

Fields

Installable

Every type this can install. A type absent from here cannot be offered.

public static readonly ServerType[] Installable

Field Value

ServerType[]

Remarks

Exposed so the picker and its test can be checked against reality rather than against a list written out a second time by hand.

Methods

InstallAsync(ServerType, string, string, VersionDetails, string, int, int, IProgress<string>?, bool, CancellationToken)

Installs type for a Minecraft version into folder.

public Task<ServerJarInstaller.InstallResult> InstallAsync(ServerType type, string folder, string mcVersion, MinecraftVersionService.VersionDetails details, string javaPath, int minRamGb, int maxRamGb, IProgress<string>? log, bool writeLoaderJvmArgs = true, CancellationToken ct = default)

Parameters

type ServerType
folder string
mcVersion string
details MinecraftVersionService.VersionDetails
javaPath string
minRamGb int
maxRamGb int
log IProgress<string>
writeLoaderJvmArgs bool
ct CancellationToken

Returns

Task<ServerJarInstaller.InstallResult>

Remarks

The RAM figures are here because Forge and NeoForge need them written into user_jvm_args.txt during the install — their own run script reads that file, and without it the server ignores the memory the user asked for.

writeLoaderJvmArgs exists for the one caller that must not touch it: the change-loader dialog offers to keep a run script the user wrote themselves, and overwriting the memory settings it reads would quietly undo their edit.
