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:

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!

Does it say "An error occured while saving/creating homes to homes.json"? If so, refine your try catch to be more specific.

It doesn't, it prints out the one Home object that is in the list (though doesn't save to file)

Edit: the file is also created successfully with no errors

Edit #2: Someone on spigot told me that I have to call FileWriter#close() after the writing and now it works!
