[resolved] Error: Could not find or load main class. when running a Talend Job

Anonymous — Tue, 13 Sep 2016 14:36:46 GMT

Hello,
we closed Talend Open Studio and got a .Metadata error.
I deleted .Metadata and tried to import the old project. The Problem here is, that for all my Jobs, the Java classes are gone, except for one.
Of course he can't find the Main Class, when there is no one.
So my question is:
Is there ANY way to generate those Javaclasses? SHOULD they be created while importing a Project? How and when are they created?
BTW:
When I tried to Import a Project, it took forever, it was like a loop - the folder got >10GB (originally 2GB), so I aborted.
Sometimes its imported really fast.
When I duplicate an old Job, there is no Files generated in "Workspace - ETL-Projects - .Java - .Classes
There should be Files like ... "XYtFilterRow_1.class" or "XYtMap_1_Struct.class"
Edit:
I have exported old .jar's for nightly Jobs - Can i use them somehow to create those classes?
Tried also another Version. And I'm on Java 1.7, aaaand ONE Job does work, because, the classes for this Job are in my classes Folder.

Please - I seriously need help!
Thanks
D.
