Logs are an essential part when it comes to debugging your server and figuring what went wrong. This page will show some basic logging examples and will try to explain what you can do to fix your issues, when encountering them. If you’re looking for details about specific mods that can cause problems with SpongeForge, then we recommend checking the Mod Compatibility page first.
Lista de chequeo
Whenever you encounter a crash or warning make sure you set SpongeForge or SpongeVanilla up correctly. Here’s a short checklist to help you out. If you’re unsure on how to acquire the information needed, have a look at the Archivos de Registro page. It explains how you get the desired answers out of your log files.
¿Está Java 8 instalado y está utilizando Sponge?
Sponge requiere Java 8 y se cerrará al usar Java 7 o una versión anterior.
¿Está instalada la versión recomendada de Forge?
Usually SpongeForge will run on older or newer Forge builds than the recommended build. However, it is strongly advised to run the recommended build only. If you encounter a crash and your versions are mismatching, match them first and try again. If you’re unsure which Forge build you need, take a look at the SpongeForge section of Leyendo el Nombre del Archivo de Descarga.
Are there any other coremods installed?
Some coremods modify Forge or Minecraft in a way that makes it impossible to run SpongeForge properly. If you have coremods installed and Sponge crashes, try to remove them and test again. Please report any incompatible coremods on GitHub. This allows staff to solve these issues as soon as possible.
¿Están todos los complementos que está utilizando compilados contra la compilación de Sponge deseada?
SpongeAPI is subject to change sometimes. When you try to use an older plugin on the most recent Sponge build and a crash occurs, try downgrading Sponge or contact the plugin author to get an updated plugin. If you’re on an older Sponge build and a recent plugin crashes, try to update Sponge first. If that doesn’t fix the issue, contact the plugin author and ask for a fix.
Separando un complemento defectuoso
Si el problema persiste, intente eliminar todos los complementos y vuelva a agregarlos uno por uno mientras intenta iniciar el servidor cada vez que agrega un complemento.
Si todavía no está seguro de por qué y qué se quebró exactamente, eche un vistazo a su registro de fallas. Algunos bloqueos comunes y soluciones comunes se enumeran a continuación.
Nota
If you encounter a bug it is usually a good idea to create a backup first, then try to reproduce it, then narrow it down by removing mods. Only then should you report the error. If the error occurs in the absence of Sponge plugins, try removing SpongeForge. If the error persists its not related to Sponge. Its usually a good idea to report bugs to the mod authors first as they have good knowledge of the parts of code they are working with. However you can always contact us for questions. For more information see Reportando Errores.
Advertencias generales
Una fuente común de errores y fallos es una versión no coincidente entre SpongeForge y Forge o SpongeForge y los complementos. Primero veremos la advertencia general que Forge nos ofrece al cerrarse:
WARNING: coremods are present:
SpongeForge (sponge-1.8-1521-2.1DEV-750.jar)
Contact their authors BEFORE contacting forge
Esto no es un error o fallo, solo es Forge que le dice que una Modificación esencial (aquí: SpongeForge) está instalada. Forge le recomienda ponerse en contacto con los desarrolladores de Sponge primero, antes de pedir ayuda a Forge. Nada de que preocuparse.
Excepciones comunes
Aquí hay algunas excepciones comunes y algunas razones por las que pueda encontrarlas.
Nota
Si se produjo un cierre, error o cualquier otro mal funcionamiento no incluido aquí, infórmelo en Sponge Forums o en GitHub. Esto ayudará a otros, que están teniendo el mismo problema.
SpongeForge y Forge no coincidentes
[12:59:21] [main/ERROR] [mixin/]: @Mixin target net.minecraftforge.event.world.BlockEvent$NeighborNotifyEvent was not found mixins.forge.core.json:event.block.MixinEventNotifyNeighborBlock
This is a common crash when you try to run SpongeForge on the wrong Forge build. Note that the target/Mixin can vary. Always match Forge against SpongeForge! If you’re unsure which version of Forge is required and you already got your SpongeForge build, take a look at the SpongeForge section of Leyendo el Nombre del Archivo de Descarga.
Otros errores comunes
Caused by: java.lang.ClassNotFoundException: org.spongepowered.api.event.state.ServerStartedEvent
Caused by: java.lang.NullPointerException
El primer error indica que falta una Class; el segundo es una excepción NullPointer (de puntero nulo) que indica que el complemento que está tratando de usar depende de los parámetros faltantes. Esto sucede cuando intenta ejecutar un complemento más antiguo en una versión más nueva de SpongeForge o SpongeVanilla y viceversa.
java.lang.AbstractMethodError: net.minecraft.entity.player.EntityPlayerMP.getTabList()Lorg/spongepowered/api/entity/living/player/tab/TabList;
at (...)
Un AbstractMethodError ocurre cuando un complemento intenta llamar a un método que aún no está implementado. Compruebe si está ejecutando la compilación más reciente de Sponge y actualice si hay una versión más nueva disponible. Si el problema persiste, repártelo en el rastreador de problemas oficial, en los foros o en el IRC. También puede solicitar la implementación de la característica que falta.
[Server thread/INFO]: Starting minecraft server version 1.8
[Server thread/ERROR]: Encountered an unexpected exception
java.lang.NoClassDefFoundError: org/spongepowered/api/event/game/state/GameStartingServerEvent
Nota
Lea el registro de ejemplo completo aquí: :download: Reporte de cierre de SpongeForge 575 con un complemento creado contra la compilación 750 </files/crashlogs/crashlog-sponge575-plugin750.txt>
A NoClassDefFoundError occurs when the plugin tries to access a class that isn’t on the classpath. This happens
when the API got adjusted or refactored lately and you’re trying to run an older plugin on a newer build of Sponge
and vice versa. Always try to use the correct version! Either ask the Plugin author which Sponge version he builds
against or try updating/downgrading your SpongeForge or SpongeVanilla to solve this.
Exceptions at Runtime
There are two kinds of errors that may occur on modded servers:
Plugin internal errors, such as NullPointerExceptions during command execution. These errors are logged using the standard Java error handler.
Errors during the ticking of worlds or entities. Sponge prints out more structured errors to provide as much information as possible.
Before we look into the details of what caused the exception, make sure that you read all of the error report. Sometimes the error is explained in the error report itself (or a few lines above or below it); sometimes it is indicated by a warning during startup.
The following stacktrace shows an example of this special handling (excluding the line prefix with time and severity):
/******************************************************************************************************************************/

/******************************************************************************************************************************/

/******************************************************************************************************************************/
This stacktrace contains the most important version numbers, as well some information about the phase the server was in.
In this case a NullPointerException has been thrown during EntityTickPhase. At this point it’s important to
check which plugins are involved with the crash. This requires some research as you have to match the package names with
mod names; checking the Caused by blocks may also help.
javaclasses can be ignored during the error search.net.minecraftis the vanilla Minecraft code. If only these elements are present, it’s either a Minecraft bug or a coremod.org.spongepoweredis from Sponge itself, having only these and Minecraft packages present usually indicates a Sponge bug (or another coremod being present).Other classes have to be mapped to their mods by hand. In this case there is this entry
com.example.extendedaiplugin; Java projects are usually named following this formatgroupId.groupId.artifactId. The group is usually a domain backwards; in this caseexample.com, followed by the name of the project also known as artifact, for more information on package naming in Java you can refer to its official docs. This plugin is probably calledextendedaiplugin, when in doubt, searching the web for the full package name can help.
Advertencia
Be careful when coremods are present. It can mean that, although a Minecraft class was reported as the cause, it does not mean the code executed is necessarily part of the Minecraft source, and could have been added by a third party. You can check your logs for loaded coremods and potentially find the culprit by removing them one by one. Be warned the issue may only occur when certain coremods are loaded at the same time.
