transitive="true" is the default, and won't help you solve your circular
dependency problem. If you want to disable transitivity, use
transitive="false" and you won't have any circular dependency problem. But
I'm not sure to get what you really want, so here are some ideas about how
to handle circular dependencies:
- break the circular dependencies between your modules: cleanest, but not
always achievable
- break the circular dependencies in configurations, for instance A->B->A
breaked in A(conf1)->B(conf1);B(conf2)->A(conf2): sometimes easier to
achieve than first solution, but not very easy to maintain
- use a circular dependency strategy adapted to your needs: you can allow
circular dependencies, thus not requiring any change in your modules: use
this when you can't break your circular dependencies at all.

HTH,

Xavier

The basic idea is that to compile my project, I want to use "compile" config
