org.apache.sling.adapter is defined as compile dependency - should be defined as scope=provided (or without scope)

fixed in next release of deps for 6.4.0, 6.4.8, 6.5.0, 6.5.6, 6,5,7 + cloud deps

the concept is to declare all dependencies without scope - scope should be defined in the modules referencing the dependency

definitely! - this is an oversight
