i have the following code that tries to create a jwt token. there will always be an error as shown below whenever it tries to execute SignatureAlgorithm signatureAlgorithm = SignatureAlgorithm.HS256;

I have manually deleted the jwt jar file and update maven again to reinstall the jar but the issue still persist.

Any help will be greatly appreciated!

//Sample method to construct a JWT
public static String createJWT(String id, String issuer, String subject, 
        String payload, String role, String name, long ttlMillis) {
    String jwt = "";

    try {
        //The JWT signature algorithm we will be using to sign the token
        SignatureAlgorithm signatureAlgorithm = SignatureAlgorithm.HS256;

        long nowMillis = System.currentTimeMillis();
        Date now = new Date(nowMillis);

        //We will sign our JWT with our ApiKey secret
        byte[] apiKeySecretBytes = DatatypeConverter.parseBase64Binary(apiKey.getSecret());
        Key signingKey = new SecretKeySpec(apiKeySecretBytes, signatureAlgorithm.getJcaName());

        //Let's set the JWT Claims
        JwtBuilder builder = Jwts.builder()
                                    .setIssuedAt(now)
                                    .setSubject("test")
                                    .claim("role", role)
                                    .claim("name", name)
                                    .setIssuer("tester")
                                    .signWith(io.jsonwebtoken.SignatureAlgorithm.HS256, signingKey);
                                    //.signWith(signatureAlgorithm, apiKey.getSecret().getBytes("UTF-8"));
                                    //

        //if it has been specified, let's add the expiration
        if (ttlMillis >= 0) {
        long expMillis = nowMillis + ttlMillis;
            Date exp = new Date(expMillis);
            builder.setExpiration(exp);
        }

        //Builds the JWT and serializes it to a compact, URL-safe string
        jwt = builder.compact();

    } catch (Exception ex) {

    }
    return jwt;
}

I have solved that issue on gradle by using

implementation "io.jsonwebtoken:jjwt-api:0.11.0"
implementation "io.jsonwebtoken:jjwt-jackson:0.11.0", {exclude group:'io.jsonwebtoken', module:'jjwt-api'}
implementation "io.jsonwebtoken:jjwt-impl:0.11.0", {exclude group:'io.jsonwebtoken', module:'jjwt-api'}

NoClassDefFoundError is a run time issue. Try adding the jar entry in your manifest file, this should help you fixing your problem.

Add please this into your pom.xml:

<dependency>
    <groupId>io.jsonwebtoken</groupId>
    <artifactId>jjwt-impl</artifactId>
    <version>0.11.2</version>
    <scope>runtime</scope>
</dependency>
