> *We added a new dependency (_velocity-tools_) and the project didn't work any more. We've found that one transitive library (_antlr_ used by _struts_ and _hibernate_) is missing in the installed WAR file.*
> It looks like the _antlr_ transitive dependency is ignored from _hibernate_ dependencies by plugin choosing _struts-1.2.9_ one while eventually _struts_ is replaced by _1.2.7_ version which does not have _antlr_ dependency.
> There is a workaround to the problem - dependencies might be rearranged to include the missing library back (e.g. by moving _struts-1.2.7_ from _parent_ to _ui_ but only before _velocity-tools_ - see the test case) however the problem is that the plugin behavior is unpredictable.
> *Test case:*
> There are root, parent, common, model, ui POM files. The purpose is to create dependency tree deep enough (_ui_ depends on _model_ and inherits from _parent_, _model_ depends on _common_). They include external dependencies (_velocity-tools_, _struts_, _hibernate_).
> * WAR artifact created from the root or _ui_ POM does not contain _antlr_ in WEB-INF/lib which is required by _hibernate_
> * after removing _velocity-tools_ from ui/pom.xml _antlr_ library is included properly
