[1.15.2] ExampleMod runServer.launch - Could not dispatch a message to the daemon


Anwinity

Recommended Posts

Hey There,

 

First, let me state that I just (today) started playing around with minecraft forge. I haven't really played minecraft or done any modding in years, so I am a bit inexperienced here. That being said, I do development (mostly Java) for a living, so I am quite familiar with most of these technologies. However, we use Maven at work and not Gradle, so I am a little noobish on the gradle concepts. I hope I am not just missing something simple gradle related. Anyway, I think I followed the documentation pretty well, but I cannot get the server (runServer.launch) to work properly.

 

Let me explain what I have done thus far.

 

Using:

JDK 8 Update 251 (Latest JDK8)

Eclipse IDE for Enterprise Java Developers - Version: 2019-12 (4.14.0) - Build id: 20191212-1212

MDK 1.15.2 - 31.1.0 (Recommended / Latest)

 

  • Downloaded MDK, extracted.
  • Found docs at https://mcforge.readthedocs.io/en/1.15.x/gettingstarted/#getting-started-with-forge
  • copied build.gradle, gradlew.bat, gradlew, gradle/ to a new folder called "ExampleMod"
  • Edited build.gradle and changed below items (nothing else, just trying to run example for the moment):
    • group = 'com.anwinity.examplemod'
    • "Specification-Vendor": "anwinity",
    • "Implementation-Vendor": "anwinity",
  • Powershell, went to new directory, ran ".\gradlew --stacktrace genEclipseRuns" - BUILD SUCCESSFUL - celebrated a little bit 
  • Open Eclipse
  • File -> Import -> Gradle -> Existing Gradle Project -> Selected "ExampleMod" folder -> success
  • Copied over ExampleMod src files including ExampleMod.java, META-INF/mods.toml, pack.mcmeta
  • Changed package to com.anwinity.examplemod
  • ModID is still "examplemod" in build.gradle and ExampleMod.java
  • Right Click runServer.launch -> Run As -> runServer
  • It runs, gets to this point in console, then hangs for a minute or so, then just quits. Nothing seems to happen.
    • [m[36m[12:37:11] [pool-2-thread-1/DEBUG] [ne.mi.fm.lo.mo.ExplodedDirectoryLocator/SCAN]: Exploded directory scan complete C:\dev_mc\projects\ExampleMod\bin\main
      [m[36m[12:37:11] [pool-2-thread-1/DEBUG] [ne.mi.fm.lo.mo.Scanner/SCAN]: Scanning C:\dev_mc\projects\ExampleMod\bin\main with language loader javafml
      [m[36m[12:37:11] [pool-2-thread-1/DEBUG] [ne.mi.fm.ja.FMLJavaModLanguageProvider/SCAN]: Found @Mod class com.anwinity.examplemod.ExampleMod with id examplemod
      [m
  • Tried running the runData.launch in the same way. It launches the UI and everything seems to work ok.
  • Tried running the runClient.launch in the same way. It launches and seems to work fine. I see ExampleMod in the mod list with all of the properties there.
  • Scratch head, try to google for answers about runServer, but nothing seemed to help.
  • Here I am. Halp plz.

I decided I could probably run this from command line... which I did and this is the error it gives.

 

Noteworthy errors:

...any ideas?

K so... I've tried a number of things based on stuff I've found online. Nothing has seemed to work yet.

 

I thought it might be my anti virus. I tried adding various exception, which did not help. Then I tried outright disabling my antivirus altogether. No help. I tried this on multiple computers - my personal desktop which has AVG, and my work laptop which has Symantic Endpoint Protection. Both have the same issue.

 

I tried a gradlew clean. I tried deleting the daemon stuff in the .gradle folder. I tried deleting the .gradle folder altogether.

 

I tried downloading the latest gradle version (6.3) and running it from command line using that instead of gradlew... it was a long shot, but suffice it to say that did not work.

 

No idea what else to try at this point...

Ok, some more info...

 

PS C:\dev_mc> java -jar .\forge-1.15.2-31.1.0-launcher.jar
FATAL ERROR, You need to run the installer. The libraries required to launch a server are missing

 

This is weird. As far as I know, I have installed the server.

I've run forge-1.15.2-31.1.0-installer.jar and ran both the client and server installation, which both appeared to run successfully.

 

I guess I could probably develop using just the runClient, but I'd really like to test stuff using a dedicated server environment.

 

I'm going to proceed with the runClient for now... but if anyone has any ideas for anything else I can try here, please let me know...
