Note
The bootstrap simply checks if required files match the following filename patterns, hence you must have the original filenames:
There must be a minecraft_server.{mcversion}.jar in the root folder.
The forge jar must have it’s original name as it had when downloaded from files.minecraftforge.net, i.e. forge-{mcversion}-{forgeversion}-universal.jar.
There must be a SpongeForge jar in the mods/ folder with it’s original name i.e. spongeforge-{mcversion}-{forgebuild}-{spongeversion}.jar
Caution: This may fix issues, however not guaranteed, it may even cause other issues.
Using this should be a last resort if there is no viable alternative.
I’m getting the error Failed to load Launch class
So it’s not finding the net.minecraft.launchwrapper.Launch
What can cause this issue and how can I fix it?
Edit: Just have to run the server once with forge then it’ll run with bootstrap
Yeah that’s it. I was about to ask if the server had been launched before.
You can see it expects to find some files when you launch it. It won’t download missing libraries.
@Dmouse92 Make sure the forge jar has it’s original name, the jar detection simply relies on finding the file based on some filename matching rules.
It should look something like this: forge-{mcversion}-{forgeversion}-universal.jar
ive got sponge being loaded instead of the forge jar and the server boots up without any errors but once in game, even as an op, i dont have any of the spongeforge commands and when i put a plugin in such as total economy, i dont have any of the commands from them
When you say you have sponge loaded instead of the forge jar…
You either didn’t read the instructions on sponge, or missed something.
The SpongeForge jar NEEDS to be in your mods folder.
You need a minecraft.1.10.2.jar and forge jar in the root of your server,
and you boot from this spongeboot strap jar.
ooooohhh, i didn’t realized it needed to have spongeforge in the mods folder aswell, i feel stupid lol
edit: so i put the spongeforge in the mods folder, have the spongebootstrapper being what its booted from in the serverstart.bat and its still erroring out
Im assuming its a modpack? If so, undo all the changes you did for sponge, run the FTBInstall, and then do the changes for sponge. (Add sponge in, boot from bootstrap) The Bootstraper does not retrieve library files at all, it is expected that you have forge properly installed before starting.
so i exctracted a new serverfiles. started the server once, then did the forge install. added the spongeforge file to mods, put the spongebootstrapper in the folder, edited settings.bat and serverstart.bat so that instead of %forgejar% it used the spongebootstrapper instead. and it always came up “Unable to access jarfile spongebootstrap-0.2.0”
ive got it launching, i was forgetting to put the .jar after the spongebootstrap -.- and then i changed the FTBLauncher thing to Forge like it said to do above, and now it will start up and go through the whole process until it gets to generating the worlds, right after RF Tools generates there worlds it crashes.

EnderIO: Found the following problem(s) with your installation (That does NOT mean that Ender IO caused the crash or was involved in it in any way. We add this information to help finding common problems, not as an invitation to post any crash you encounter to Ender IO's issue tracker. Always check the stack trace above to see which mod is most likely failing.):
* An unsupportted RF API is installed (1.7.10R1.3.1 from BrandonsCore-1.10.2-2.1.3.82-universal.jar).
Ender IO needs at least 1.8.9R1.2.0B1 and will NOT work with older versions.
An unsupported base software is installed: 'sponge'. This is NOT supported.
This may (look up the meaning of 'may' in the dictionary if you're not sure what it means) have caused the error. Try reproducing the crash WITHOUT this/these mod(s) before reporting it.

the only problem i run into is im using the Direwolf20 1.10.2 server which is version 1.4.1 and the forge in it is version 2185 and the most recent sponge uses 2221. would the latest version work with my server?
