Hi,

 

after a long break from Minecraft I'm finally back (if anyone noticed that I took a break )

 

So now I wanted to start modding MC again and run directly into a problem:

FAILURE: Build failed with an exception.

* What went wrong:
A problem occurred configuring root project 'primeval-forest'.
> Failed to notify project evaluation listener.
   > MISSING REPLACEMENT DATA FOR MAPPING_CHANNEL
   > MISSING REPLACEMENT DATA FOR MAPPING_CHANNEL

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

BUILD FAILED

Total time: 6.336 secs

 

Does anyone know what this mean and how to fix this?

If you need more information, please leave a comment behind.

 

Thx in advance.

Bektor

 

EDIT:

Here is the build.gradle file:

 

// For those who want the bleeding edge
buildscript {
    repositories {
        jcenter()
        maven {
            name = "forge"
            url = "http://files.minecraftforge.net/maven"

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

/*

ext.configFile = file "build.properties"

configFile.withReader {

def prop = new Properties()
prop.load(it)
ext.config = new ConfigSlurper().parse prop
}

Its basically just the one I used in my old 1.7 projects, but this time updated to 1.8.9.

 

build.propeties file:

minecraft_version=1.8.9
primeval_major=0
forge_version=11.15.0.1684
primeval_minor=1
primeval_build=0

Maybe I'm over looking it but where is your  mapping entry lines in the build.gradle file ?

Eg:

  mappings = "stable_20"

 

my 1.8.9 Example build.gradle :

https://github.com/TechStack/TechStack-s-HeavyMachineryMod/blob/1.8.8_redux/build.gradle

 

 

it May or may not be the cause of this exact error. Hope it helps

Oh, thx. 

 

And nope, you've not over looked it, I did while updating the build.gradle.

Now its working without any problems.
