+                jackson-annotations2-api plugin. Declare it explicitly so the
+                generated Plugin-Dependencies manifest entry lets the jfrog
+                plugin classloader resolve JsonInclude$Include through the
+                same loader jackson2-api uses, avoiding a LinkageError
+                (loader constraint violation) at runtime.
