             Summary: Ivy does not apply namespace rules for cached deps
                 Key: IVY-1593
                 URL: https://issues.apache.org/jira/browse/IVY-1593
             Project: Ivy
          Issue Type: Bug
          Components: Core
    Affects Versions: 2.5.0-rc1
         Environment: Define an Ivy project with the following resolver:

{noformat}
<ibiblio name="Jcenter"
                     namespace="fixnamespace"
                     m2compatible="true"
                     usepoms="true"
                     root="http://jcenter.bintray.com/"; />
{noformat}


Create {{ivy.xml}} with the following dependency:

{noformat}
<dependency org="org.jboss" name="jboss-retro" rev="1.1.0""/>
{noformat}

After the running a first resolve task (and thus creating the cache), add the 
following namespace rules:

{noformat}

   <namespaces>
       <namespace name="canonize">
           <rule>
               <fromsystem>
                   <src org="jboss" module="javassist"/>
                   <src org="org.jboss" module="javassist"/>
                   <src org="javassist" module="javassist"/>
                   <dest org="org.javassist" module="javassist"/>
               </fromsystem>
       </namespace>
    </namespaces>
{noformat}

            Reporter: Pedro de Carvalho Gomes


Ivy does not apply namespace rules to cached dependencies. Thus, making such 
rules "invisible", and potentially breaking builds and/or downloading 
duplicated dependencies. 

The issue is created by the cached the ivy file at 
{{${HOME}/.ivy2/cache/org_def/name_def/ivy-rev_def.xml}}. This file is created 
by converting from the original POM. It contains transitive dependencies with 
the wrong definitions that should be fixed with namespaces.

After, the namespace definition is added. However Ivy won't recreate the 
{{ivy-rev_def.xml}}, and will resolve the transitive dependency with the wrong 
namespace.
