Talend Open Data Studio - Build problem - Cannot invoke "java.util.List.iterator()" - CodeGeneratorInternalTemplatesFactory.getTemplates()" is null

neo_vcamas — Fri, 15 Nov 2024 21:21:46 GMT

Hello,

I downloaded the latest version of Talend Open Data Studio(8.0.1) from the website, but I have been unable to build the project despite trying it on several different laptops. I can't see the code generated in the Code tab as it normally should. I've tried various configurations, but none have been successful.

I also tried it with Java 11 and Java 18 versions, but that didn't yield any results either. Below, I'm sharing a screenshot and stack trace information. I would greatly appreciate your assistance.

Can you please upload the Studio Support logs? (Please go to Studio Help -> Support logs -> Save it with a name as .zip file).
