l = Jackson
s = @JsonInclude
p = your project
t = ProcessedDeclaredLicense
My answer wasn’t precise about what part of the export means. Java annotations are special in this regard. The whole thing can be reformulated to the question “Do I need s in the classpath in order to compile a first class citizen u that is not in p but that imports t?” Is that a yes or no 
(a yes means an API dependency).
