Solved JSON won't save to file (using GSON)

I am trying to save some data (a list) to a JSON file, when I print the json string out it's all fine but it won't save to the file.
code:

Code (Java):

private List<Home> homes = new ArrayList<>();
    private File dataFolder = new File(getDataFolder(), "data");
    private File homesFile = new File(dataFolder, "homes.json");
    private Gson gson;

public void onEnable() {
        gson = new Gson();
        saveDefaultConfig();
        dataFolder.mkdirs();
        try {
            homesFile.createNewFile();
        } catch (IOException e) {
            getLogger().info("An error occured while creating file homes.json");
            e.printStackTrace();
        }
    }

public void saveJson() {
        try {
            gson.toJson(homes, new FileWriter(homesFile));
            getLogger().info(gson.toJson(homes));
        } catch (JsonIOException e) {
            getLogger().info("An error occured while saving homes to homes.json");
            e.printStackTrace();
        } catch (IOException e) {
            getLogger().info("An error occured while saving homes to homes.json");
            e.printStackTrace();
        }
    }
 

(The list isn't empty)
Thanks in advance!

 

Perfect it works! Thank you!
