SOLVED: Fatal error when using pixelmon mod

[blockly_hacker]

 

I am running Forge 1.12.2-forge1.12.2-14.23.4.2705 (installed as client, downloaded from https://download.nodecdn.net/containers/reforged/universal/release/Pixelmon-1.12.2-6.2.2-universal.jar) on OS X with Java 1.8.0_74 (Oracle) and have installed Pixelmon-1.12.2-6.2.2-universal.jar. I am able to launch forge. When I select Singleplayer and create a new world, everything works until the "Loading terrain" screen. After that, I either get the error "A fatal error has occurred, this connection is terminated" or the application just hangs.

 

There are many stack traces in the log referencing this error:

 

Caused by: java.lang.NoSuchMethodError: net.minecraftforge.fml.common.discovery.ModDiscoverer.findModDirMods(Ljava/io/File;)V

 

When I remove Pixelmon from the mods directory, I am able to create and play in a new world.

 

I have seen other posts suggesting that the latest version of Pixelmon is buggy. If that is the case, can anyone recommend a Forge version and Pixelmon version that work together? Alternately, is there another site from which I should have gotten the mod?

 

Thanks.

Problem solved. :-)

1.8.0_74 is a rather old version of Java. Perhaps try updating to a more recent 64-bit version of Java 8?

Pixelmon is trying to access internal forge methods that have been removed.

Try to update Pixelmon or speak to the mod authors.

Thank you, diesieben07, but Pixelmon was recently discontinued due to corporate pressure.

 

RedstoneMaster256, thank you too for your reply. Based on what diesieben07 said, that would be unlikely to have an effect, and I am reluctant to upgrade Java, since this is also my development machine, and my current build works.

 

I'm still hoping someone can let me know a combination of versions that work.

[diesieben07]

You will have to abandon Pixelmon then.

I was able to run Pixelmon by downloading Version 1.12.2-6.3.1 Forge 2705 from Pixelmon Reforged.
