Properly named java models don't import

I don't know what's the problem, I've been recently making models and suddenly I can't import them, im not sure if it's the blockbench's new update fault because i tested if the same problem occurs in the older versions and it does, although my older models work properly when i try to import them. Here's what it says when i try to import it:

Here's the model code:

// Made with Blockbench 3.5.2
// Exported for Minecraft version 1.14
// Paste this class into your mod and generate all required imports

public class thesummoner extends EntityModel {
    private final RendererModel head;
    private final RendererModel nose;
    private final RendererModel body;
    private final RendererModel leg0;
    private final RendererModel leg1;
    private final RendererModel rightarm;
    private final RendererModel leftarm;
