Job source code blanked!

Anonymous — Sat, 16 Nov 2024 06:46:14 GMT

Hi, I am using Talend Open Studio for Big Data 7.1 on Windows 7 at the moment, i erroneously emptied the "target" folders: ProjectDir\poms\jobs\process\JobId\target now the souce files in ProjectDir\poms\jobs\process\JobId\src\main\java had been blanked.

* The build of the job obviously fail
* Adding deleting components does not regenerate the java sources
* The "Code" tab on the job shows, obviously, nothing
* Cleaning the windows Temp directory does not help
* Restarting Talend doees not help
* The Java file of the object is existant but empty
* Reinstalling Talend does not help

Any clue on this?

Thanks in Advance

Disable half of the job from the bottom all the way up to about half way, and check the code tab. if it generates, then the problem is with the lower half, otherwise the upper half, repeat disabling/re-enabling sections until you home in on the component giving you the issue.

Watch out for disable/enable to tHashInput/Output as they may not reconnect to the right companion.
