Maven/Gradle way to calculate the total size of a dependency with all its transitive dependencies included

Question

I would like to be able to perform an analysis on each of my project POMs to determine how many bytes each direct dependency introduces to the resulting package based on the sum

Answer 1

I do not know any way to show the totals but you may get a report for your project which can show per dependency size information. Please check this maven plugin : http://maven.apache.org/plugins/maven-project-info-reports-plugin/dependencies-mojo.html
