Error while trying to compile my ModCoderPack mod for Minecraft

Question

I am trying to make a mod for Minecraft using Mod Coder Pack, however when I try to recompile I get the error that I cannot use lambda expressions but I have set Java 1.8 in Eclipse and I am not sure how to tell it to recompile using -source 8.

Any help would be appreciated, Thanks.

src\minecraft\me\rhysespuff\aeriolus\modules\ModuleManager.java:46: error: lambda expressions are not supported in -source 1.6 return modules.stream().filter(module -> module.getName().equals(name)).findFirst().orElse(null); ^

(use -source 8 or higher to enable lambda expressions)

Answer 1

MCP is no longer updated and uses a java version before java 8, which is why lambdas won't work. I would suggest switching to Minecraft Forge or Spigot, which are modern api's that are still supported and work with java 8.
