Hey guys,

 

I don't know what I did, but after upgrading my mod to 1.12.2 from 1.12, many things seem to have broken. Here's my steps:

1. I updated my build.gradle file (you can see it below)
2. I ran gradlew clean
3. Ran gradlew setupDecompWorkspace
4. Ran gradlew eclipse

Spoiler

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 = "1.3.0"
group = "com.DragonFerocity.expanded" // http://maven.apache.org/guides/mini/guide-naming-conventions.html
archivesBaseName = "expanded"

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

minecraft {
    version = "1.12.2-14.23.0.2503"
    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_20171003"
    // 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"
      
    // 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'
    }
}

 

Now things are broken.

 

Whenever I run my mod from eclipse, it keeps telling me that every single one of my items are being registered twice

...

If I run gradlew build, it tells me that there a variable that I can clearly see doesn't exist:

Spoiler

R:\...\java\com\DragonFerocity\expanded\items\ModHoe.java:40: error: cannot find symbol
        this.speed = material.getDamageVsEntity() + 1.0F;
                             ^
  symbol:   method getDamageVsEntity()
  location: variable material of type ToolMaterial
Note: Some input files use or override a deprecated API.
Note: Recompile with -Xlint:deprecation for details.

Which is the 7th line in the following code

 public ModHoe(String name, ItemTool.ToolMaterial material)
    {
        this.toolMaterial = material;
        this.maxStackSize = 1;
        this.setMaxDamage(material.getMaxUses());
        this.setCreativeTab(CreativeTabs.TOOLS);
        this.speed = material.getDamageVsEntity() + 1.0F;
        setUnlocalizedName(Ref.MODID + ":" + name);
        setRegistryName(Ref.MODID + ":" + name);
    }

 

As far as I know I didn't change anything significant between upgrading from 1.12.2 from 1.12. I can post more code, or a link to my github if needed.

 

Your help is appreciated.

I would try removing all the eclipse files and reimporting the project.

Are there eclipse files in the src directory? I couldn't see any.

 

One thing I did try was creating a new project from scratch using forge, then I edited the build.gradle file with the correct info and copied my src folder over to the new project. The same thing occured.

Are you using latest or stable?

I guess I downloaded the most recent. Should I go back to the last stable?

I went back to version 14.23.0.2491 and the problems still persist. However, it does build correct now when I run gradlew build

Here's the difference in the files between my last version and the version that's giving me errors.

That says your blocks are being registered twice, not your items.

 

If you look at the end of the initBlocks method:

for(Block block : blockList) {
   event.getRegistry().register(block);
}
for(Block block : blockList) {
   event.getRegistry().register(block);
}

That's why right there, you do that loop twice.
