public enum AnsiColor implements AnsiElement {
    DEFAULT("39"),
    BLACK("30"),
    RED("31"),
    GREEN("32"),
    YELLOW("33"),
    BLUE("34"),
    MAGENTA("35"),
    CYAN("36"),
    WHITE("37"),
    BRIGHT_BLACK("90"),
    BRIGHT_RED("91"),
    BRIGHT_GREEN("92"),
    BRIGHT_YELLOW("93"),
    BRIGHT_BLUE("94"),
    BRIGHT_MAGENTA("95"),

    BRIGHT_WHITE("97");
    private final String code;
    private AnsiColor(String code) {
        this.code = code;
    }
    public String toString() {
        return this.code;
    }
}

启动成功！
