Could not resolve dependencies for project com.adobe.learning:aem-learning-core:jar:1.0.1: Could not find artifact org.apache.commons:commons-imaging:jar:1.0-R1534292 in central (https://repo.maven.apache.org/maven2)
If you ever come with this error that means the maven central doesn't have the artifact, and we have to use the adobe profile to successfully build the code.
add parameter "-Padobe-public" with your maven build command.
e.g. mvn clean install -Padobe-public
