http://www.intellij.net/tracker/idea/viewSCR?publicId=34071 I'd like to be able to use the product dependency rules in an (as of yet embryonic) plugin. Doesn't have to be anything fancy, just something like [code] ProjectDependencyManager mgr = ProjectDependencyManager.getInstance(project); if(mgr.dependencyViolatesRules(myDependentClass, myDependencyClass)) { //do something } [/code] No rush on this, it's likely to be Q4 before this plugin (BattleSpaces) is ready for primetime. --Dave Griffith.
