Good morning,
as suggested by DonManfred I create a new thread for this issue.
I tried the example AttributesExtractor inB4J starting from this thread "[SOLVED] Write #Attribute to Textfile":
I compiled the file in Release mode.
It produces a jar file named result.jar.
In order to be compliant with what is suggested do I need to rename it from result.jar to attributes.jar?
Or can I use the following instruction?
