Been having the same issue here (java.lang.NoSuchMethodError: gregtech.api.recipes.RecipeMap.findRecipe(JLjava/util/List;Ljava/util/List;)Lgregtech/api/recipes/Recipe;)

*except I am on GTCE v 1.8.3.416

your both running way to new of gregtech with GTadditions. GTadditions has not been updated to the latest version of GTCE so you need to pick an older build of GTCE if you want to run GTadditions, or get shadow of greg as a replacement to GTAdditions
