Random issue for Publishing a Talend job into the Nexus 3

xrocq — Fri, 15 Nov 2024 22:17:13 GMT

Hello,

I'm working with Talend subscription version 7.3.1

I am publishing my Jobs from the studio to the Artifact Repository on the nexus 3.

Then i deploy the release or snapshot created on the TAC from as an Artifact Repository task.

Sometimes (Randomly) i have to redo the publish because the release or snapshot deployed is impossible to run and always print the same error message which is :

"Error: Could not find or load main class "

So i think that the building process is making a "corrupted" binary ? am i right ?

How can i improve the reliability of the publish process ?

I have a machine with the studio, a machine for the TAC and a machine for the Nexus 3

Maybe i have to install Talend studio on the Nexus 3 machine to shortcut the network steps ?

If someone have ideas....

Hello,

Does this problem only occur in the TAC?

Could you please share your TAC technical logs and Job server log so that we could review the full error and identify why it might be occurring.

Yes this problem can sometimes occur in the studio (1% of the time) but i just restart the studio and its fixing the problem.

I know that. After publishing a job the studio performs a refresh of the whole project (no idea why) and it does that, the jobs cannot be open (mostly you will get a strange error method.

The same applies to the build process. It will fail.

If you deploy a job, wait until all running actions in the studio are finished and than open and edit other jobs.

Also we are facing the problem, sometimes the studio does not recognise compile errors and create damaged artifacts.

Could not find main class is always a symptom which is caused by a failed compilation process and this is unrecognised.

@jlolling @xrocq you can also do a regenerate all pom from studio. In CI it's now mandatory (exactly because of the above symptoms...) on 7.3 it's best practice.

But this class not found error I listed like 10+ reasons in this article: https://talendsupport.force.com/talend/s/article/Resolving-class-and-JAR-related-issues?language=en_US
