int io.jsonwebtoken.SignatureAlgorithm.getMinKeyLength()' no such method error while generating a token key for authentication

Issue

Hello all I am trying to use JJWT to generate a security token for authenticating users. But getting this error. Here is my pom.xml file:

Here is my method to generate a token if needed

protected void successfulAuthentication(HttpServletRequest req, HttpServletResponse res, FilterChain chain,
                                            Authentication auth) throws IOException, ServletException {

        Date exp = new Date(System.currentTimeMillis() + EXPIRATION_TIME);
        Key key = Keys.hmacShaKeyFor(KEY.getBytes());
        
        Claims claims = Jwts.claims().setSubject(((User) auth.getPrincipal()).getUsername());
        String token = Jwts.builder().setClaims(claims).signWith(SignatureAlgorithm.HS512, key).setExpiration(exp).compact();
        res.addHeader("token", token);


    }

How to solve this problem? I tryed before to changed version of jjwt to 0.11.2 but got a build eror it couldn't find a jar file.

Solution

You did not implement right io.jsonwebtoken dependencies.
These are the three dependencies you have to implement correctly;

        <dependency>
            <groupId>io.jsonwebtoken</groupId>
            <artifactId>jjwt-api</artifactId>
            <version>0.11.2</version>
        </dependency>
        <dependency>
            <groupId>io.jsonwebtoken</groupId>
            <artifactId>jjwt-impl</artifactId>
            <version>0.11.2</version>
        </dependency>
        <dependency>
            <groupId>io.jsonwebtoken</groupId>
            <artifactId>jjwt-jackson</artifactId>
            <version>0.11.2</version>
      </dependency>
