java.lang.ClassNotFoundException: org.glassfish.jersey.client.JerseyClientBuilder Error?

I am encountering the error: java.lang.ClassNotFoundException: org.glassfish.jersey.client.JerseyClientBuilder however i have imported the classes so am not sure why it is popping up. My build.gradle and code is below:

private String getAccessToken() {
    try {
        Log.e("tree","get access entered");
        javax.ws.rs.client.Client client = javax.ws.rs.client.ClientBuilder.newClient();
        javax.ws.rs.client.Entity<String> payload =
                javax.ws.rs.client.Entity.text("grant_type=client_credentials&redirect_uri=https://facebook.com/intellidevco");
        javax.ws.rs.core.Response response = client.target("https://v2.api.xapo.com/oauth2/token")
                .request(MediaType.TEXT_PLAIN_TYPE)
                .header("Authorization","Basic MjVjMDZjZDU3M2FmNDFjYzo4NjE4ZWY2NDE1MDI0MTE3YjhiOTI3YzhkZmQ1NmZlMw==")
                .post(payload);
Log.e("tree","response completed");
            String body = response.readEntity(String.class);
            Log.e("tree","body "+body);
        } catch(Exception e) {
Log.e("tree","token exception "+e.getMessage());
        }
        retu "";
