Ok so, I worked on porting my mod from 1.6.2 to 1.7.2 a while back, and I wanted to continue this so I started setting up Gradle and eclipse.

After a couple of hickups I got it (I think), but now it FML seems to throw an error when trying to process my file :

I tried creating a new file and moving the content from the old file to the new, but that didnt change a thing.

I also tried cleaning and building gradle.

 

This is the file it says being corrupt:

package com.Mod_Ores.BiomeGen;

public class BiomeEventMarona extends Event
{
    public final BiomeGenBase biome;

    
    public BiomeEventMarona(BiomeGenBase biome)
    {
        this.biome = biome;
    }
    
    public static class CreateDecorator extends BiomeEventMarona
    {
        public final BiomeDecorator originalTheBiomeDeco;
        public BiomeDecorator newTheBiomeDeco;
        
        public CreateDecorator(BiomeGenBase biome, BiomeDecorator original)
        {
            super(biome);
            originalTheBiomeDeco = original;
            newTheBiomeDeco = original;
        }
    }

    public static class BlockReplacement extends BiomeEventMarona
    {
        public final int original;
        public int replacement;

        public BlockReplacement(BiomeGenBase biome, int original, int replacement)
        {
            super(biome);
            this.original = original;
            this.replacement = replacement;
        }
    }
    

    @SideOnly(Side.CLIENT)
    public static class BiomeColor extends BiomeEventMarona
    {
        public final int originalColor;
        public int newColor;

        {
            super(biome);
            originalColor = original;
            newColor = original;
        }
    }

    @HasResult
    public static class GetVillageBlockID extends BlockReplacement
    {
        public GetVillageBlockID(BiomeGenBase biome, int original, int replacement)
        {
            super(biome, original, replacement);
        }
    }

    @HasResult
    public static class GetVillageBlockMeta extends BlockReplacement
    {

        {

        }
    }
    
    @SideOnly(Side.CLIENT)
    public static class GetGrassColor extends BiomeColor
    {

        {

        }
    }
    
    @SideOnly(Side.CLIENT)
    public static class GetFoliageColor extends BiomeColor
    {

        {

        }
    }
    
    @SideOnly(Side.CLIENT)
    public static class GetWaterColor extends BiomeColor
    {

        {

        }
    }
}

 

Thanks for the help in advance!

You probably compiled for java 8 You should not do that.

Also update to at least 1.7.10...

I do Forge for free, however the servers to run it arn't free, so anything is appreciated.

Well at first I compiled for java 8, then I noticed that I shouldnt use Java 8 so I stepped back to 7. Is there any way I can make this file go "un-corupted".

Also I was working on getting my mod for 1.7.2 and I need to check what was broken at that point before I start compiling for 1.7.10.
