SpongeForge server cannot run on Eclipse

RaycusMX · May 19, 2019, 7:16am

I’m using Java 8 and Eclipse 2018-09. I tried following this document to launch server on IDE and debugging the plugin but it crashed.

Here is what exactly I have done.

Create a new gradle project named “SpongePlugin” and edit the build.gradle file:

build.gradle

buildscript {
    repositories {
        maven {
            name = 'forge'
            url = 'https://files.minecraftforge.net/maven'
        }
    }

    dependencies {
        classpath 'net.minecraftforge.gradle:ForgeGradle:2.3-SNAPSHOT'
    }
}

plugins {
    id 'org.spongepowered.plugin' version '0.9.0'
}

dependencies {
    compile 'org.spongepowered:spongeforge:1.12.2-2768-7.1.5:dev'
}

apply plugin: 'net.minecraftforge.gradle.forge'

minecraft {
    forgeVersion = '1.12.2-14.23.5.2768'
    mappings = 'snapshot_20171003'
}

Refresh gradle project and run this command:

gradlew setupDecompWorkspace eclipse

It shows:
MISSING REPLACEMENT DATA FOR RUN_DIR
and:
BUILD FAILED
So I have to refer to Forge MDK and edit the build.gradle file:

minecraft {
    forgeVersion = '1.12.2-14.23.5.2768'
    mappings = 'snapshot_20171003'
    runDir = "run"
}

Then I repeat step 2 and it works fine.

Create a package “com.example” and copy the example from the tutorial to it:

ExamplePlugin.java

package com.example;

import org.apache.logging.log4j.Logger;
import org.spongepowered.api.event.Listener;
import org.spongepowered.api.event.game.state.GameStartedServerEvent;
import org.spongepowered.api.plugin.Plugin;

import com.google.inject.Inject;

@Plugin(id = "exampleplugin", name = "Example Plugin", version = "1.0", description = "Example")
public class ExamplePlugin {
	
	@Inject
	private Logger logger;
	
	@Listener
	public void onServerStart(GameStartedServerEvent event) {
		logger.info("Successfully running ExamplePlugin!!!");
	}
	
}

Launch server with run configuration “SpongePlugin_Server”. It crashes with this log:

I think I was strictly following the tutorial but it just won’t work. Could someone please tell me how to fix this?

simon816 · May 19, 2019, 10:47am

That’s an old version of mappings. Sponge’s stable-7 branch currently uses snapshot_20180808

github.com

SpongePowered/Sponge/blob/stable-7/gradle.properties#L9


      
          name=SpongeCommon
          implementation=Common
          description=Shared code between SpongeForge and SpongeVanilla
          url=https://www.spongepowered.org
          organization=SpongePowered
          
          minecraftVersion=1.12.2
          recommendedVersion=8-SNAPSHOT
          mcpMappings=snapshot_20180808
          
          # We use VanillaGradle instead of an official ForgeGradle plugin.
          # Compared to the regular tweaker-server plugin, SpongeCommon has all run tasks disabled
          # and the Minecraft workspace defined as "provided" so they won't conflict with the implementation.

Many thanks to you. It finally works!
Besides, I’d like to know how to figure out these two values by myself (in the future maybe)?

minecraft {
    // TODO: Configure Forge build here
    forgeVersion = '2705'
    // TODO: Replace with your mappings version, e.g. stable_39 or snapshot_20180814
    mappings = 'YOUR_MAPPINGS_VERSION'
}

And this configuration won’t actually work due to lack of “runDir” (not be mentioned in the tutorial). However, even if I add this value, it’ll still give a warn like
Version string 'unspecified' does not match SemVer specification
(not be mentioned also).
How to improve this?

JBYoshi · May 19, 2019, 2:18pm

The Forge version number is included in the SpongeForge version.

To fix the SemVer warning, set your project’s version in build.gradle using version 'x.y.z' (replace x, y, and z with actual numbers).

RaycusMX · May 19, 2019, 2:58pm

How to figure out the mapping version of each build? Do I have to check it on github?
