Modularizing our code => How to debug cyclic dependencies on the features
Hi guys,
I would need your help regarding the best practices to modularize the code
into "building blocks". I'm working on breaking a monolith into smaller
chunck but I'm faceing some issues having apparently cyclic dependencies in
my different features definitions. The problem is that I can't figure out
where is the cycle. Do you guys have a tool to analyse feature dependencies
? Or how do you manage the feature files when the project becomes of a
bigger size ?
I believe I have a cycle because the maven build hangs when I build the
karaf distribution. A jstack analysis of the build process shows me this
stack trace:

Hi Guillaume,
Here it is:

In the mean time, any advice on how to debug this ?
Thanks!

Re: Modularizing our code => How to debug cyclic dependencies on the features
Posted by Guillaume Nodet <gn...@apache.org>.
Please raise a JIRA issue.
I think there is definitely a problem loading repositories with cycles, but
it should be quite easy to support that I think.
