Talend Cloud - issue with exchange component

I have installed tfileexcelworkbookopen component from exchange, but sometimes it gives an error saying main class not found, I always reload the component folder and restart the talend . but issues arises whenever I change the branches. Is there any permanent fix for this.

Hello,

If you get a missing jars error, when using the component in a Job, try the following procedure:

  1. Install the component again (without uninstalling the component installed previously).
  2. Delete the file <Talend Studio installation dir>\configuration\ComponentCache.javacache and restart Talend Studio.
  3. The file ComponentCache.javacache caches the dependencies and information of all components after the first launch of a Talend Studio. It avoids reloading all components at each start of the Talend Studio, saving some time. In case you need to remove this cache, then all components will need to be loaded again at the next start of the Talend Studio in order to build this cache again.

Feel free to let us know if it works.

Best regards

Sabrina

Hello,

It seems something related to workspace. Did you still get this error when you start the studio with new project?

Is it OK with you when you re-install your studio?

Best regards
