File di Log

Logfiles are an essential part when it comes to debugging your server and figuring what went wrong. This pages contains logfiles from SpongeForge and SpongeVanilla servers including short descriptions.

SpongeForge logfiles

SpongeForge writes several logfiles to the /logs folder located inside your servers directory. As of Forge 1521 these are:

  1. fml-junk-earlystartup.log

  2. fml-server-latest.log

  3. latest.log

fml-junk-earlystartup.log

  • Java 8 64bit Update 51

  • Windows 8.1 x64

  • the directory Java was installed to (Line 4)

Avvertimento

SpongeForge won’t run on Java 6 (1.6.x) or Java 7 (1.7.x). If you encounter an error stating that you run an older Java build than Java 8, please update your JRE to 1.8.x and try again!

Reading logfiles

If you’re unsure on how to read a common crashlog, you’ll find help here, but first we need a crashlog. For this short introduction we will just use an example crash from the Debugging page: Example crashlog of an outdated SpongeForge build.

WARNING: coremods are present:
SpongeCoremod (sponge-1.8-1499-2.1DEV-575.jar)
Contact their authors BEFORE contacting forge

The first thing you’ll notice is a Warning that coremods are present. Nothing to worry about here, that’s not an error, just a warning to contact Sponge support, not Forge.

java.lang.NoClassDefFoundError: org/spongepowered/api/event/game/state/GameStartingServerEvent

A few lines below the actual error is found. In this case it’s a NoClassDefFoundError If you’re unsure what that means, head over to our Debugging page. If it’s a common error, it will be listed there. If it isn’t, you can always ask on the forums for help! Make sure you provide the full crashlog.

Luckily your systems details are included at the bottom of the crashlog:

Minecraft Version: 1.8

U      Core{unknown} [Core Plugin] (Core.jar)
Loaded coremods (and transformers):
SpongeCoremod (sponge-1.8-1499-2.1DEV-575.jar)

This indicates that

  • Minecraft 1.8 with Forge 1521 was running on

  • Java 8 Update 51 (64bit version) and that

  • 2 additional mods were installed

    • SpongeForge 1.8-1499-2.1DEV-575 (which is build #575) and

    • Core

Nota

Please note that the other three installed mods (mcp, FML, Forge) are required on every Forge server and necessary to run properly.

Now the following assumptions can be made:

  • maybe the plugin crashed the server

  • SpongeForge doesn’t match the Forge version: 1499 required, 1521 installed

If you want to know how to solve this, head over to our checklist on the Debugging page.
