mcreator geckolib animation help

So I've been trying to make a mod, and I created a custom mob with Blockbench, animated it with the GeckoLib plugin for blockbench, saved it as a .java file, and tried to import it into MCreator. It just showed an error message saying: "Your model is not a valid Java model! Make sure that all model parts have a valid Java name and that your model is in fact a Java model with a valid syntax."

please help
