Forge installer doesnt get replaced with actual forge server jar

[Osiris-Team]

I just tested it on my system and a popup opens up where I need to select server and then it installs it into the .minecraft folder.
And this repeats every time you enter .start to launch the server.

for now disable the server updater and give the absolute path in the start command which should be something like (on windows)
java -jar C:\Users\arman\AppData\Roaming.minecraft\libraries\net\minecraftforge\forge\1.18.2-40.2.14\forge-1.18.2-40.2.14-server.jar

ForgeUpdater has been removed because of this issue.
Will need to find a better & reliable way to fetch the installer jar and build server jar from that.

[Osiris-Team]

We could get the real server jar from this path maybe? C:\Users\arman\AppData\Roaming.minecraft\libraries\net\minecraftforge\forge\
would require us to find out the username maybe.
How is it on linux though?

Just found the forge installer has a installServer commandline argument that installs the server into the current directory, which would be I think exactly what we need: https://github.com/MinecraftForge/Installer/blob/74183ebebae9bff4719500c76721987af52b746b/src/main/java/net/minecraftforge/installer/SimpleInstaller.java#L73

@HSGamer yeah just tested it out and it works, the command looks something like this, after downloading the installer:
java -jar .\forge-1.20.2-48.1.0-installer.jar --installServer

I'm still not sure where the server jar finally is, probably it doesnt exist and all the libs get added to the default mc server jar at boot, thats why autoplug should just update the start command to start-command: ./run.sh (or .bat if windows).

So can we add the original code for the forge updater back? And also update the command to run the installer?

The problem is that it creates the full server setup, not a single server jar.

@HSGamer here is what ChatGPT says about the forge start command:

It looks like you've provided a command line configuration for launching a Minecraft Forge server using the Forge Mod Loader (FML) and some specific libraries. Let me break down the important components of this command:

1. Classpath (specified by -p):

   • Various JAR files are specified in the classpath, including libraries related to Google Guava, Forge, ASM (Objectweb ASM), secure modules, and other dependencies required for running a Forge server.

2. Module Path (specified by --add-modules ALL-MODULE-PATH):

   • This option indicates that all JAR files in the specified classpath will be treated as modules. This is a way to use the module system introduced in Java 9.

3. Exports (specified by --add-exports jdk.naming.dns/com.sun.jndi.dns=java.naming):

   • This option adds a specific export statement for the given package. In this case, it exports the com.sun.jndi.dns package to java.naming.

4. System Properties (specified by -D):

   • Several system properties are set using the -D flag. Notable ones include:
     • java.net.preferIPv6Addresses=system: This sets the preference for IPv6 addresses.
     • ignoreList: Specifies a list of JAR files to be ignored.
     • libraryDirectory: Specifies the directory where libraries are located.
     • legacyClassPath: Specifies the classpath for legacy dependencies.

5. Main Class and Launch Parameters:

   • The main class is specified as net.minecraftforge.bootstrap.BootstrapLauncher.
   • Additional parameters specific to Forge server launch are provided, such as --launchTarget, --fml.forgeVersion, --fml.mcVersion, --fml.forgeGroup, and --fml.mcpVersion.

It seems like this command is designed to launch a Minecraft Forge server with specific versions and configurations. Ensure that all the specified libraries are available in the specified directory, and the required dependencies are correctly set up. Additionally, make sure you have the appropriate Java version installed to run this Minecraft Forge server.

@HSGamer basically you can think of it as an extracted server jar. When usign the installer agin those files get updated so I dont see the problem.

Another problem is the start script file. It's different for each OS.

[Osiris-Team]

The actual command inside the .sh and .bat should be the same. But this shouldn't be a worry of the server updater.

There are still problems with this updater

• If we want to provide a single server jar as the output, this can't do.
• If we provide the update for the installer, the user will need to run the installServer command AND the start file.
• If we want to support fetching old versions, the link to that is different from the one in newer versions (probably from 1.12 and above).

Since I don't work on Forge Updater, I will leave this to you or someone who can solve these problems above.

[Osiris-Team]

Instead of providing the jar as output we can provide the run.sh/bat script. This should be ok since its only for forge and there isn't really another alternative.

The user won't have to run anything, server-updater will run the installer jar.

Supporting older versions can be done later, its not a priority now I would say. Since those older versions probably stopped receiving updates anyways.

We won't. It's different from Bungee Updater.
