I’m having trouble with a missing class while working on Google Drive API setup

I followed the steps to set up the Google Drive API in my Java project and added the required Maven dependency:

<dependency>
    <groupId>com.google.apis</groupId>
    <artifactId>google-api-services-drive</artifactId>
    <version>v2-rev78-1.15.0-rc</version>
</dependency>

However, when I try to build my project, I get compilation errors saying that com.google.api.client.json.jackson.JacksonFactory cannot be found. This class seems to be referenced in the sample code but isn’t available in my classpath.

Has anyone encountered this issue before? What additional dependencies do I need to include to make this work? Or is there an alternative class I should use instead of JacksonFactory for handling JSON operations with the Google Drive API?

Had the same issue last month. That dependency version’s ancient - Jackson got reorganized in newer releases. Add google-api-client separately, usually fixes the missing JacksonFactory. Or just switch to gson like Oscar said, works fine.

Had this same issue migrating an old project. Your version’s pretty outdated - it’s from before Google moved JacksonFactory to a separate artifact. Just add the jackson2 dependency: com.google.http-client google-http-client-jackson2 1.43.3 Better yet, upgrade to Drive API v3 with current dependencies. It handles JSON processing better and you won’t hit these classpath problems. I’d go with upgrading since v2’s deprecated anyway.

The JacksonFactory is deprecated, which likely explains the issue you’re encountering. I faced a similar challenge with an outdated version of the Google API client library. Your current dependency is outdated and requires an upgrade. Modify your Maven configuration to use a more recent version, such as google-api-services-drive v3-rev20220815-2.0.0. Additionally, consider switching to GsonFactory for JSON operations, as this should resolve the compilation errors.
