Issue with Google Calendar: Unable to locate com.google.api.client.json.JsonFactory.fromInputStream

Currently, I'm developing a Spring-MVC application and I'm facing an issue while trying to integrate Calendar functionality. The problem seems to be related to authentication due to a json error. I have been using Googles sample code but it appears to be outdated, so I made some adjustments. Would appreciate if you could take a look at the modifications. Error log :

java.lang.NoSuchMethodError: com.google.api.client.json.JsonFactory.fromInputStream(Ljava/io/InputStream;Ljava/lang/Class;)Ljava/lang/Object;
    com.google.api.client.googleapis.auth.oauth2.GoogleClientSecrets.load(GoogleClientSecrets.java:167)
    com.journaldev.spring.utility.OAuth.authorize(OAuth.java:73)

The Oauth class is where I am implementing calendar functionality.

public class OAuth {

    private static final String APPLICATION_NAME = "appname";

    private static final java.io.File DATA_STORE_DIR =
            new java.io.File(System.getProperty("user.home"), "" +
                    "/Store/calendar_sample");

    private static FileDataStoreFactory dataStoreFactory;

    private static HttpTransport httpTransport;

    private static final com.google.api.client.json.JsonFactory JSON_FACTORY = JacksonFactory.getDefaultInstance();

    private static com.google.api.services.calendar.Calendar client;

    static final java.util.List<Calendar> addedCalendarsUsingBatch = Lists.newArrayList();

    public void authorizeAndTest(){

        try {
            httpTransport = new NetHttpTransport();
            dataStoreFactory = new FileDataStoreFactory(DATA_STORE_DIR);
            Credential credential = authorize();

            client = new com.google.api.services.calendar.Calendar.Builder(httpTransport,JSON_FACTORY,credential).setApplicationName(APPLICATION_NAME).build();

            showCalenders();
            addCalendarsUsingBatch();
            Calendar calendar = addCalendar();
            updateCalendar(calendar);
            addEvent(calendar);
            showEvents(calendar);
            deleteCalendarInBatch();
            deleteCalendar(calendar);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    private static Credential authorize() throws Exception{


        InputStream inputStream = new FileInputStream(new File("/home/akshay/c0cc3b4b7502.json"));


        GoogleClientSecrets clientSecrets = GoogleClientSecrets.load(JSON_FACTORY,inputStream);

// The error occurs on this line.

   if (clientSecrets.getDetails().getClientId().startsWith("Enter")
            || clientSecrets.getDetails().getClientSecret().startsWith("Enter ")) {
        System.out.println(
                "Enter Client ID and Secret from https://code.google.com/apis/console/?api=calendar "
                        + "into calendar-cmdline-sample/src/main/resources/client_secrets.json");
        return null;
    }

    AuthorizationCodeFlow flow = new GoogleAuthorizationCodeFlow.Builder(httpTransport,JSON_FACTORY,clientSecrets,
            Collections.singleton(CalendarScopes.CALENDAR)).setDataStoreFactory(dataStoreFactory).build();

Answer №1

It is important to consider the following points:

  1. The dependency com.google.gdata.core is not needed for the Calendar API. If it is not required for another Google API, it can be removed.

  2. There are two implementations of the google-http-client: google-http-client-jackson and google-http-client-jackson2. One of them should be removed.

  3. Some dependencies such as 

    google-api-client-auth-oauth2:1.2.3-alpha
    and google-api-client:1.4.1-beta are unnecessary and outdated.

  4. The versions of google-api-services-calendar and google-http-client-jackson2 do not match. Use 

    google-api-services-calendar:v3-rev121-1.19.0
    with 
    google-http-client-jackson2:1.19.0
    .

  5. Replace the google-oauth-client-java6 dependency with google-oauth-client-jetty if the LocalServerReceiver class is needed.

Below is an updated list of dependencies and a modified OAuth class:

    <dependency>
        <groupId>com.google.apis</groupId>
        <artifactId>google-api-services-calendar</artifactId>
        <version>v3-rev121-1.19.0</version>
    </dependency>

    <dependency>
        <groupId>com.google.http-client</groupId>
        <artifactId>google-http-client-jackson</artifactId>
        <version>1.19.0</version>
    </dependency>

    <dependency>
        <groupId>org.springframework.security.oauth</groupId>
        <artifactId>spring-security-oauth2</artifactId>
        <version>2.0.3.RELEASE</version>
    </dependency>
    <dependency>
        <groupId>com.google.oauth-client</groupId>
        <artifactId>google-oauth-client-jetty</artifactId>
        <version>1.19.0</version>
    </dependency>

Please note that the path to the json file needs to be updated in the OAuth class:

public class OAuth {

    private static final String APPLICATION_NAME = "APPNAME";

    private static final java.io.File DATA_STORE_DIR =
            new java.io.File(System.getProperty("user.home"), "" +
                    "/Store/calendar_sample");

    private static FileDataStoreFactory dataStoreFactory;

    private static HttpTransport httpTransport;

    private static final com.google.api.client.json.JsonFactory JSON_FACTORY = new JacksonFactory();

    private static com.google.api.services.calendar.Calendar client;


    public void authorizeAndTest() {

        try {
            httpTransport = new NetHttpTransport();
            dataStoreFactory = new FileDataStoreFactory(DATA_STORE_DIR);
            Credential credential = authorize();

        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    private static Credential authorize() throws Exception {


        FileReader credentialsReader = new FileReader(new File("client_secret_47576556653-go0fkf4c56dohm6m16s2400qed5ps410.apps.googleusercontent.com.json"));

// It gives me an error for line below.
        GoogleClientSecrets clientSecrets = GoogleClientSecrets.load(JSON_FACTORY, credentialsReader);
        if (clientSecrets.getDetails().getClientId().startsWith("Enter")
                || clientSecrets.getDetails().getClientSecret().startsWith("Enter ")) {
            System.out.println(
                    "Enter Client ID and Secret from https://code.google.com/apis/console/?api=calendar "
                            + "into calendar-cmdline-sample/src/main/resources/client_secrets.json");
            return null;
        }

        AuthorizationCodeFlow flow = new GoogleAuthorizationCodeFlow.Builder(httpTransport, JSON_FACTORY, clientSecrets,
                Collections.singleton(CalendarScopes.CALENDAR)).setDataStoreFactory(dataStoreFactory).build();

        return new AuthorizationCodeInstalledApp(flow, new LocalServerReceiver()).authorize("example@example.com");
    }

Answer №2

To resolve the issue, simply comment out the dependency from your Pom.xml file and give it a try:

    <!--dependency>
        <groupId>com.google.api.client</groupId>
        <artifactId>google-api-client-auth-oauth2</artifactId>
        <version>1.2.3-alpha</version>
    </dependency-->

Instead of this:

<dependency>
    <groupId>com.google.api.client</groupId>
    <artifactId>google-api-client</artifactId>
    <version>1.4.1-beta</version>
</dependency>

We hope this solution works for you.
