dependencies failed using branch attribute (and extra attrubutes)
-----------------------------------------------------------------

                 Key: IVY-1141
                 URL: https://issues.apache.org/jira/browse/IVY-1141
             Project: Ivy
          Issue Type: Bug
          Components: Core
    Affects Versions: 2.1.0
         Environment: windows 
            Reporter: Daniel Schwager


*** Investigation
i tried to use the branch attribute inside my projekt DEV like this:

        <ivy-module version="1.1">
                <info ... module="DEV" ....

                <dependency org="testng" name="testng" 
                        branch="mybranch1" rev="latest.integration"  
                        conf="compile,tests->default"/>
                .....

If I now try to resolve my dependencies, it failed
because ivy 2.1.0 try to resolve the latest version (5.6) of testng/testng
which has NO branch-keyword inside it's ivy.xml. The ivy.xml
of version testng/testng/4.6 contains the following:

<ivy-module version="1.1">
    <info
        organisation="testng" module="testng"
        branch="mybranch1"  revision="4.6.1.2"
        status="release"         
        publication="20060227000000">
      .....

It looks like the resolver skip this 4.6.1.2 version (which is the only one 
containing the 
branch attribute "mybranch1") and try to download the 5.6 (containing NO branch 
attribute !). 

I go the following error message:

[ivy:configure] :: Ivy 2.1.0 - 20090925235825 :: http://ant.apache.org/ivy/ ::

*** Make it reproducable

I create a VERY small sample project (build.xml & ivy.xml)
using a sample ivyrepos on our server.

Could somebody look closer to the problem by downloading the project from
    http://www.opensource-online.org/fileadmin/swd/ivy/ivy-test.zip

To run, yust unzip and start "ant -f build.xml" and you can see the failure:

*** Same problem using extra attributes instead auf branch attribute
if tried a workaround not using the branch-keyword but defining a own extra 
atrribute like this:

<ivy-module version="2.0" xmlns:swd="http://softwaredemo.de/ivy/extra";>
 ...
                <dependency org="testng" name="testng"  swd:suite="mybranch-e2" 
rev="latest.integration"  
                                        conf="compile,tests->default"/>

But this tells me a similar result - also a failure.

Danny
