How to convert a resource attribute of type string to type slice/string array?

[felixscheinost]

I am trying to feed traces from a Java application using the Java agent to the collector and then to some exporter which unfortunately expects a resource attribute of type slice.

I am finding no way to set a slice resource attribute using solely configuration, no code. As I am using the Java agent code on the client side should be the last resort.

Then I looked if I could convert the string to a slice using the collector but it seems that no processor is able at all to create new slices. I checked:

• resource processor can't handle slices at all, not through convert neither through NewAttributeValueRaw which can't create slices as well.
• transform processor can't create new slices I think? I dug through the source code to find some sort of array literal or something like that but couldn't find any.
• resourcedetection + env like the Java SDK this can only create strings, not slices
