The tool I used to do this analysis for ArgoUML itself (although we never
tackled removing the package cycles) was Classycle:
http://classycle.sourceforge.net/ It is available as an Eclipse plugin as
well as standalone tool.  One nice addition since the last time I used it
is support for Dependency Definition Files.  This allows you to describe
allowable dependencies (e.g. your architectural layers) and it will check
for violations. http://classycle.sourceforge.net/ddf.html  Looking at
http://argouml.tigris.org/source/browse/argouml/trunk/tools/classycle/ it
looks like it's been 7-8 years since I used it for ArgoUML.

IntelliJ's dependency analysis looks pretty powerful too (although I
haven't used it):
https://www.jetbrains.com/idea/features/dependency_analysis.html

While adding dependencies to the Java reverse engineering may be useful for
other stuff, it's not how I'd recommend finding package cycles.  A tool
designed for that purpose will do a better job.
