Sample Name

Modified version of https://developers.google.com/sheets/api/quickstart/java

private Credential getCredentials(NetHttpTransport httpTransport) {
    try {
        GoogleClientSecrets clientSecrets = GoogleClientSecrets.load(JSON_FACTORY, new InputStreamReader(new FileInputStream(credentialsFilePath)));
        GoogleAuthorizationCodeFlow flow = new GoogleAuthorizationCodeFlow.Builder(httpTransport, JSON_FACTORY, clientSecrets, SCOPES)
                .setDataStoreFactory(new FileDataStoreFactory(new File(credentialsFilePath))).setAccessType("offline")
                .build();
        return new AuthorizationCodeInstalledApp(flow, new LocalServerReceiver.Builder().setPort(8888).build()).authorize("user");
    } catch (IOException e) {
        e.printStackTrace();
        return null;
    }
}

Expected Behavior

Was expecting to receive a Credential object after successfully authenticating with the google api

Actual

Check your client secrets file to make sure it's correct. Possible that you downloaded credentials in the wrong form.

That error indicates it's not in the expected format as isn't either for a server-side web app or installed (desktop) app. Corresponding code: https://github.com/googleapis/google-api-java-client/blob/master/google-api-client/src/main/java/com/google/api/client/googleapis/auth/oauth2/GoogleClientSecrets.java

Ping @aeslami3574 -- please verify your credentials are the correct type. Otherwise will close issue as not reproducible.

I had the same issue using the wrong credentials.json I have downloaded for a service account, created to access google sheets from a web application. I was banging my head until I discovered that I needed an OAuth credentials, set "Web Application" as application type json file that has been downloaded from google cloud console.

My credentials file should looks like this:

{
	"web": {
		"client_id": String,
		"project_id": String,
		"auth_uri": String,
		"token_uri": String,
		"auth_provider_x509_cert_url": String,
		"client_secret": String
	}
}

My workaround: Don't use the client secrets, instead, directly build the credentials.

Import this library

<dependency>
        <groupId>com.google.auth</groupId>
        <artifactId>google-auth-library-oauth2-http</artifactId>
        <version>1.3.0</version>
</dependency>

InputStream in = SheetsQuickstart.class.getResourceAsStream(CREDENTIALS_FILE_PATH);
if (in == null) {
        throw new FileNotFoundException("Resource not found: " + CREDENTIALS_FILE_PATH);
}
GoogleCredentials googleCredentials = GoogleCredentials.fromStream(in).createScoped(SCOPES);

Sheets service = new Sheets.Builder(HTTP_TRANSPORT, JSON_FACTORY, new HttpCredentialsAdapter(googleCredentials))
                .setApplicationName(APPLICATION_NAME)
                .build();

Sheets service = new Sheets.Builder(HTTP_TRANSPORT, JSON_FACTORY, new HttpCredentialsAdapter(googleCredentials))
                .setApplicationName(APPLICATION_NAME)
                .build();

This is the most accurate answer until today.
Hopefully, more developers can see this.

Works like a charm!
If you see this - use this

THANK YOU @Johnny850807
Hey @google come on, update your docs!
