Issue with job Construction Could not initialize class !

[Safus]

Hello,

I have a job that uses AWS Athena connection. The Job works fine from the Studio, but when I construct the Job and use the bat file to execute it I have this error : 

Exception in thread "Thread-15" [statistics] disconnected
[statistics] disconnectedjava.lang.NoClassDefFoundError: Could not initialize class org.talend.components.api.component.ComponentDefinition

I checked the lib folder and I can see all the jars I should use among other jars  : 

...
components-api-0.28.2.jar
AthenaJDBC42-2.1.5.1001.jar
aws-java-sdk-athena-1.12.767.jar
aws-java-sdk-core-1.12.767.jar
aws-java-sdk-sts-1.12.767.jar
...

what am I missing here ? 

Best regards,
