It works fine, but it has a lot of warnings, how to fix it?

:frowning_face:Maybe it won’t affect the run, but I want to fix it please:(

All those warnings look perfectly normal, and shouldn’t cause any issues.
As a note, often time when log messages are labeled as WARN, it simply means that if things do break here is some likely more useful information.

Yes, I want to solve this and avoid problems with the next plugin installation.

There is nothing to fix. All those warnings can be safely ignored, they are recommendations to us as the Sponge developers but because of the nature of what we do, we either cannot fulfil them, or don’t need to.

To break it down:

[21:10:01] [main/WARN] [FML]: The coremod FMLCorePlugin (net.minecraftforge.fml.relauncher.FMLCorePlugin) is not signed! 
[21:10:01] [main/WARN] [FML]: The coremod FMLForgePlugin (net.minecraftforge.classloading.FMLForgePlugin) is not signed!

We can’t do anything about that, that’s not Sponge.

[21:10:01] [main/WARN] [FML]: The coremod SpongeCoremod (org.spongepowered.mod.SpongeCoremod) is not signed!

That’s a recommendation to Sponge to sign our jars, but we don’t need to and it doesn’t affect how the game runs at all. You cannot do anything to remove this.

[21:10:06] [main/WARN] [mixin]: Static binding violation: PRIVATE overwrite method initializeConnectionToPlayer in mixins.common.core.json:server.MixinPlayerList cannot reduce visibiliy of PUBLIC target method, visibility will be upgraded.

This is just to tell you that a method that Sponge changes was specified as a “private” method, but the method we target is actually public, so Mixin (what we use to edit Minecraft code) fixes this problem and warns us that’s the case. Without this warning, the server would actually break.

[21:10:12] [Server thread/WARN] [FML]: Missing English translation for FML: assets/fml/lang/en_us.lang
[21:10:12] [Server thread/WARN] [FML]: Missing English translation for spongeapi: assets/spongeapi/lang/en_us.lang
[21:10:12] [Server thread/WARN] [FML]: Missing English translation for spongeforge: assets/spongeforge/lang/en_us.lang

This would only matter if FML (which isn’t ours) and Sponge use the inbuilt translation system. We do not. This warning is only that, a warning, and it doesn’t apply to us. We have no way of telling the server not to warn us for it.

[21:10:12] [Server thread/WARN] [Sponge]: The mod spongeforge was designed for forge 1.12.2-14.23.5.2825 but version 14.23.5.2847 is in use. It may not work properly. 
[21:10:12] [Server thread/WARN] [Sponge]: The mod spongeforge was designed for forge 1.12.2-14.23.5.2825 but version 14.23.5.2847 is in use. It may not work properly.

This is self explanatory - but for the avoidance of doubt, this simply warns you that your Forge build (2847) doesn’t match the version of Forge that we use to build Sponge (2825). It’s just a warning to say “hey, if Sponge breaks, you might want to try downgrading Forge first”. But as you see, your server works fine, so ignore it.

[21:10:13] [Server thread/WARN] [Sponge]: There's no certificate fingerprint available

Again, just to do with signing. You can ignore it.

Finally, the one that you might worry about the most:

[21:10:13] [Server thread/WARN] [FML]: Potentially Dangerous alternative prefix `sponge` for name `human`, expected `spongeforge`. This could be a intended override, but in most cases indicates a broken mod.

This is indeed an intended override. If we didn’t do this, things would actually break horribly if you were to switch your server between SpongeForge and SpongeVanilla, for example. The warning is there to advise us that something might be wrong, but as it even says in the message, it could be intended. It is - the warning is better than breaking everything.


Please ignore the warnings. As I and @d4rkfly3r have explained, there is nothing to solve. Plugins are not affected by any of these warnings.

Thank you very much. There is no doubt
