Я следую примеру в здесь , чтобы разработать мой первый RESTFul API.
Пример работает правильно. Я использую Maven + Eclipse для создания RESTfull API. Вот мой pom.xml:
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

Это потому, что мне нужно реализовать аутентификацию JWT, поэтому мне нужна библиотека com.auth0 (java-jwt), поэтому я добавляю следующую зависимость в свойpom.xml.
<dependency>
<groupId>com.auth0</groupId>
<artifactId>java-jwt</artifactId>
<version>3.8.3</version>
</dependency>
После обновления проекта maven и очистки приложения при перезапуске сервера я получаю следующее сообщение об ошибке.

Я обнаружил, что мое приложение снова работает правильно, когда я закомментирую зависимость com.auth0. Я хочу знать, есть ли обходной путь для устранения ошибки?
