SAP Commerce - Integration tests fails - testing_additional_tests.txt doesn't exist

Hi !

I`m having a big time issue on executing some integration tests, after the Junit tenant is being initialized, I run the

 ant integrationtests -Dtestclasses.packages=mypackage.*

command but it fails even before starting evaluating the integration tests, here is the output :

rying to override old definition of task groovy_compile
Trying to override old definition of task groovynature_compile_core
Trying to override old definition of task groovynature_compile_web
Trying to override old definition of task touchFutureTimestamp

integrationtests:

BUILD FAILED
/opt/hybris/hybris/bin/platform/build.xml:255: The following error occurred while executing this line:
/opt/hybris/hybris/bin/platform/resources/ant/testing.xml:44: /opt/hybris/hybris/temp/hybris/testing_additional_tests.txt doesn't exist

Total time: 3 seconds

I even tried to create it manually with the same failed build result. Any clue will be appreciated, thanks.
