Java streaming bot integration with Google Sheets API issues

I’m constructing a bot in Java for a streaming service that tracks point accumulation for viewers. The plan is to utilize the Google Sheets API in place of a local database, so that viewers can easily check their points without needing to flood the chat.

I’m utilizing the Pircbot library to connect with IRC chat. The approach is straightforward - upon user entry into the chat, verify their presence in the spreadsheet and add them if they’re absent. Then, every 10 minutes, I will distribute points to active participants.

Here’s my method for handling user joins:

@Override
protected void onUserJoin(String room, String username, String login, String host) {
    try {
        SheetManager.insertNewUser(username);
    } catch (IOException e) {
        System.out.println(e);
    } catch (ServiceException ex) {
        System.out.println(ex);
    }
}

And here is the sheet management class:

class SheetManager {
    private static final String GMAIL_USER = "[email protected]";
    private static final String GMAIL_PASS = "mypassword";
    private static final String SHEET_URL = "https://spreadsheets.google.com/feeds/spreadsheets/mysheetid";
    
    public static void insertNewUser(String username) throws IOException, ServiceException {
        SpreadsheetService sheetService = new SpreadsheetService("Bot Sheet Integration");
        sheetService.setUserCredentials(GMAIL_USER, GMAIL_PASS);
        
        URL feedUrl = new URL(SHEET_URL);
        SpreadsheetEntry sheet = sheetService.getEntry(feedUrl, SpreadsheetEntry.class);
        
        URL worksheetUrl = ((WorksheetEntry) sheet.getWorksheets().get(0)).getListFeedUrl();
        
        ListEntry newRow = new ListEntry();
        newRow.getCustomElements().setValueLocal("Username", username);
        newRow.getCustomElements().setValueLocal("Points", "0");
    }
}

However, I encounter this error:

java.lang.NoClassDefFoundError: Could not initialize class
com.google.gdata.client.spreadsheet.SpreadsheetService

Is this API deprecated? What could I be overlooking? Any guidance would be appreciated!

Hit this same problem 6 months back with a channel rewards system. Yeah, it’s the GData library - Google killed it in 2021. I switched to Google Sheets API v4 with the google-api-services-sheets dependency and it worked great. Heads up though - auth is completely different. You can’t use username/password anymore. Need OAuth2 or service account creds through Google Cloud Console. Also caught me off guard: data handling changed big time. No more ListEntry objects. Now you’re using ValueRange objects and spreadsheets().values().update() calls. Steeper learning curve at first, but the new API’s way more solid and handles rate limits better.

This repetitive integration work just kills development time. Why wrestle with deprecated APIs and auth headaches when you can automate the whole thing?

I’ve built similar point tracking systems - the manual API approach becomes a maintenance nightmare. Every Google API update or new feature means you’re back debugging.

You need an automation platform that handles Google Sheets integration. Set triggers for user joins, schedule point distribution every 10 minutes, add webhook endpoints for real-time checks.

Best part? No managing OAuth tokens, rate limits, or API version changes. The platform handles infrastructure while you focus on bot logic.

Used this approach for several streaming bots - rock solid. No more auth errors or deprecated library issues.

The Google Data API was deprecated in 2021, which explains the NoClassDefFoundError you’re encountering. I recommend transitioning to Google Sheets API v4, which operates under a different structure. You should remove the old gdata library and use the google-api-services-sheets library instead. Also, the authentication method has changed; create a service account in the Google Cloud Console and utilize JSON credentials rather than hardcoding email credentials. The API’s method for managing data has shifted to batchUpdate requests instead of ListEntry objects. I completed a similar migration last year, and while it requires some upfront effort, API v4 offers enhanced reliability and security.

hit this same problem with my twitch points bot last month. yeah, gdata’s dead. just make sure you enable the sheets api in your google cloud console first - forgot that step and got a weird error even with v4. also, batch your point updates instead of calling individually. saved me a ton of api quota.

yep, google deprecated gdata a long time ago. u should migrate to sheets api v4. and seriously, don’t leave your gmail password in the code, huge security risk. look into oauth2 or use service accounts instead.
