Error: Could not find or load main class when running from Talend Open Studio

[Hemidude]

Hi all,

I have read many threads about this error but none of the solutions have helped so far.

I am using Talend Open Studio for Data Integration 7.3.1.20200219_1130 with Java 1.8.0_201

I keep getting "Error: Could not find or load main class" on my top-level job which just orchestrate tRunJobs linked by OnSubjobOK which in turn call other tRunJobs.

This is only 3 levels deep: Job Production_Full calls tRunJobs, which each call another sub-job that calls a third sub-job that actually does the work.

The sub-jobs all run perfectly at each level except the top one that orchestrates everything.

It used to work but now does not.

I have checked all the Contexts are the same Repository setting and all the Java paths seem to be OK.

No sub-job is set to "Use an independent process to run subjob".

I tried creating a new job that ran the same tRunJobs, but that failed too

I have another job in the same Project that is nested in the same way and even uses most of the same jobs - that works with no error

What am I missing?

If we follow the job design through the levels and concentrate on the first sub-job of each (all other jobs are variations of this pattern):

so UT_SC contains where UT_SC_ccntmf contains
