Could not find or load main class

[Aswini_R]

My Talend job runs successfully in Studio, but after publishing it to TMC, it throws the error: 'Could not find or load main class'. The previous version of the same job worked fine after publishing, but the current version fails. How can I resolve this issue?

Hello,

Did you test the job as a standalone job ?

Kind regards

Hi Denis,

Thank you for your response.

I'm running the standalone job by executing the .bat file. However, I'm still encountering the same error:
"Could not find or load main class."

Could you please assist me further with this?

Hi Aswini_R,

Please try this....

Clear the workspace, do a fresh publish to cloud and try again

Hi Balram,

I’ve published my job to a different workspace using a fresh version, but I’m still encountering the same issue.

Could you please assist me further with this?

Thanks
