How to add attachment using oauth accessToken (not userName & password) ?
Codes below can only do normal post to Jira (create issue or add comment):
OAuthAccessor accessor = getAccessor();
OAuthClient client = new OAuthClient(new HttpClient4());
accessor.accessToken = accessToken;
OAuthMessage request = accessor.newRequestMessage(method, url, Collections.<Map.Entry<?, ?>>emptySet(), bodyAsStream);
List<Map.Entry<String, String>> headers = request.getHeaders();
headers.add(new OAuth.Parameter(HttpMessage.CONTENT_TYPE, "application/json"));
headers.add(new OAuth.Parameter(HttpMessage.CONTENT_LENGTH, contentLength));
headers.add(new OAuth.Parameter(HttpMessage.DEFAULT_CHARSET, "UTF-8"));
OAuthMessage response = client.invoke(request, ParameterStyle.AUTHORIZATION_HEADER);
