[1.7.2] [SOLVED] Eclipse: Starting up Minecraft Mod, file corrupt?

[OwnAgePau]

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:

    {

        {

        }
    }

        public BlockReplacement(BiomeGenBase biome, int original, int replacement)
        {

            this.original = original;

        }
    }

        }
    }

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...

[OwnAgePau]

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.

[OwnAgePau]

Allright I'll set it up for 1.7.10 with java 8 and see how that goes thanks for helping so far.

[OwnAgePau]

Moving up to 1.7.10 did seem to not give any errors any more, so thanks
