Creating a static Settings class from inside that class but non static fields not updating

So I have settings file for my project that looks like the following.

@Component
public class Settings {
    private transient final BuildProperties buildProperties;
    private static Settings settingsStatic;
    private String TF_VERSION = "EMPTY";

    private static final Logger LOGGER = LoggerFactory.getLogger(Settings.class);
    private final String REPO_TF_SUBSCRIPTION = 
         "git::https://github.xxx.com/xxxxx/xxxx//subscription?ref=" + TF_VERSION);


    @Autowired
    private Settings(BuildProperties buildProperties) {
        this.buildProperties = buildProperties;
        TF_VERSION = this.buildProperties.getVersion();
        LOGGER.info("TF_VERSION is {}", this.buildProperties.getVersion());
        settingsStatic = this;
    }

    public static String getTerraformSubscriptionRepository() {
        return settingsStatic.REPO_TF_SUBSCRIPTION;
    }

}

The Logger outputs the correct version ie. 3.4.0, but when I call getTerraformSubscriptionRepository() it comes back with TF_VERSION=empty instead of what I expected, 3.4.0.

Can anyone explain to me why that would be happening.

private String TF_VERSION = "EMPTY";
private final String REPO_TF_SUBSCRIPTION = 
     "git::https://github.xxx.com/xxxxx/xxxx//subscription?ref=" + TF_VERSION);

You initialize REPO_TF_SUBSCRIPTION with TF_VERSION = "EMPTY", but because REPO_TF_SUBSCRIPTION is final, you can't modify it later, so it always be the same object, even if you modify TF_VERSION
