How to I update my Minecraft mod from 1.12.2 to Minecraft 1.15.1 on a mac

[ClueDoh]

I've found one tutorial online using windows but it doesn't work on mac. What do I do to update so I can have support on this forum cause I have mod problems that need fixing.

You would first need to run the forge installer for the version you are planning to use.

Then make an Installation in the minecraft launcher, I would point it to a new game folder (i.e. .minecraft-NEW or something). Make sure you are selecting the forge game version.

Create (or once you run once it will create it for you) a mods folder in this folder, and download mods for the appropriate version from curseforge.

 

When you are trying, what exactly are you doing, and what's the exact problem? Details, error messages, and screenshots are helpful

 

P.S: I don't use a mac, but overall the process is largely the same regardless of OS.

I'm trying to update my mod. I have built the beginning of it in forge 1.12.2 and want to update to 1.15.1. how to I do so?

 

I've made it as far as adding the build .gradle. I followed a tutorial but I eeping getting BUILD FAIL when I try "gradlew eclipse".

 

This is my build.gradle:

buildscript {
    repositories {
        jcenter()
        maven { url = "http://files.minecraftforge.net/maven" }
    }
    dependencies {
        classpath 'net.minecraftforge.gradle:ForgeGradle:2.3-SNAPSHOT'
    }
}
apply plugin: 'net.minecraftforge.gradle.forge'
//Only edit below this line, the above code adds and enables the necessary things for Forge to be setup.


version = "1.0"
group = "com.yourname.modid" // http://maven.apache.org/guides/mini/guide-naming-conventions.html
archivesBaseName = "modid"

sourceCompatibility = targetCompatibility = '1.8' // Need this here so eclipse task generates correctly.
compileJava {
    sourceCompatibility = targetCompatibility = '1.8'
}

minecraft {
    version = "1.12.2-14.23.5.2768"
    runDir = "run"
    
    // the mappings can be changed at any time, and must be in the following format.
    // snapshot_YYYYMMDD   snapshot are built nightly.
    // stable_#            stables are built at the discretion of the MCP team.
    // Use non-default mappings at your own risk. they may not always work.
    // simply re-run your setup task after changing the mappings to update your workspace.
    mappings = "snapshot_20200128"
    // makeObfSourceJar = false // an Srg named sources jar is made by default. uncomment this to disable.
}

dependencies {
    // you may put jars on which you depend on in ./libs
    // or you may define them like so..
    //compile "some.group:artifact:version:classifier"
    //compile "some.group:artifact:version"
    minecraft "net.minecraftforge:forge:1.15.1-30.0.51"
      
    // real examples
    //compile 'com.mod-buildcraft:buildcraft:6.0.8:dev'  // adds buildcraft to the dev env
    //compile 'com.googlecode.efficient-java-matrix-library:ejml:0.24' // adds ejml to the dev env

    // the 'provided' configuration is for optional dependencies that exist at compile-time but might not at runtime.
    //provided 'com.mod-buildcraft:buildcraft:6.0.8:dev'

    // the deobf configurations:  'deobfCompile' and 'deobfProvided' are the same as the normal compile and provided,
    // except that these dependencies get remapped to your current MCP mappings
    //deobfCompile 'com.mod-buildcraft:buildcraft:6.0.8:dev'
    //deobfProvided 'com.mod-buildcraft:buildcraft:6.0.8:dev'

    // for more info...
    // http://www.gradle.org/docs/current/userguide/artifact_dependencies_tutorial.html
    // http://www.gradle.org/docs/current/userguide/dependency_management.html

}

processResources {
    // this will ensure that this task is redone when the versions change.
    inputs.property "version", project.version
    inputs.property "mcversion", project.minecraft.version

    // replace stuff in mcmod.info, nothing else
    from(sourceSets.main.resources.srcDirs) {
        include 'mcmod.info'
                
        // replace version and mcversion
        expand 'version':project.version, 'mcversion':project.minecraft.version
    }
        
    // copy everything else except the mcmod.info
    from(sourceSets.main.resources.srcDirs) {
        exclude 'mcmod.info'
    }
}

 

 

This is the result I get:

 

TomMBP:Test tom$ ./gradlew eclipse

You're mixing the 1.12.2 and 1.15.x build.gradle files without understanding them.

At this point you'd be better off making a new 1.15.x project with a fresh MDK and take the opportunity to rewrite the mod, as a lot has changed in both Forge and Minecraft itself.
