"module" caot be resolved - Eclipse

So I've been working on a modded Client for Minecraft but I can't fix this thing.
(Please don't blame me if this is a obvious fault, because I'm really new to Java and I don't know much.)
Eclipse says that "module" can't be reached and first I thought that I didn't imported the right things into here. But that's not the case... (I think)
Here is the code:

public void setup() {
        if(!setup.compareAndSet(false, true))
            retu;

            final Map<Category, ModuleFrame> CategoryFrames = new HashMap<Category, ModuleFrame>();
            for(Module module : ModuleManager.getModules()){
                if (module.isCategory(me.Liam_Yves.turbo.module.Category.GUI))
                    continue;
                ModuleFrame frame = CategoryFrames.get(module.getCategory());
                if (frame == null){
                    String name = module.getCategory().name().toLowerCase();
                    name = Character.toUpperCase(name.charAt(0)) + name.substring(1);
                    frame = new ModuleFrame(name);
                    frame.setTheme(getTheme());
                    frame.setLayoutManager(new GridLayoutManager(1, 0));
                    frame.setVisible(true);
                    frame.setClosable(false);
                    frame.setMinimized(true);
                    addFrame(frame);
                    CategoryFrames.put(module.getCategory(), frame);
                }
                final; Module updateModule = module;
                Button button = new BasicButton(module.getName()){
                    public void update(){
                        setText(updateModule.getName());
                        setEnabled(updateModule.getState());
                    }
                };
                button.addButtonListener(new ButtonListener() {

                    @Override
                    public void onButtonPress(Button button) {
                        updateModule.toggleModule();
                        button.setText(updateModule.getName());
                        button.setEnabled(updateModule.getState());                             
                    }
                });
                frame.add(button, HorizontalGridConstraint.FILL);
            }


        // Optional equal sizing and auto-positioning
        resizeComponents();
        Minecraft minecraft = Minecraft.getMinecraft();
        Dimension maxSize = recalculateSizes();
        int offsetX = 5, offsetY = 5;
        int scale = minecraft.gameSettings.guiScale;
        if(scale == 0)
            scale = 1000;
        int scaleFactor = 0;
        while(scaleFactor < scale && minecraft.displayWidth / (scaleFactor + 1) >= 320 && minecraft.displayHeight / (scaleFactor + 1) >= 240)
            scaleFactor++;
        for(Frame frame : getFrames()) {
            frame.setX(offsetX);
            frame.setY(offsetY);
            offsetX += maxSize.width + 5;
            if(offsetX + maxSize.width + 5 > minecraft.displayWidth / scaleFactor) {
                offsetX = 5;
                offsetY += maxSize.height + 5;
            }
        }
    }
