[jira] Commented: (IVY-983) exclude does not work in non-trivial conf case

["stan towianski (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/IVY-983?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12976880#action_12976880 ] 

stan towianski commented on IVY-983:
------------------------------------

One general thing we figured out is that if you have a circular dependency, excludes will not work.
I do not know if that is for all excludes or not. If you have A depends on B,   and B depends on C,  and C depends on A,
then we had excludes that did not work. When we fixed the circular dependency, the exclude started working,
in this case for some apache-cxf -> geronimo_something jar.

You can find circular dependencies with something like tattletale.jar

I thought I read somewhere that excludes were supposed to happen last, though I did not find it just now,
but there must be something in ivy in the case above that will keep excludes from working.

This happened in ivy-2.1.0 and ivy-2.2.0

> I'm running into a problem with <exclude>... my ivy.xml looks like this:
> <ivy-module version="2.0">
>         <info organisation="ssn-src" module="pc"/>
>         <configurations defaultconfmapping="default->default">
>                 <conf name="default" />
>                 <conf name="provided" description="they are provided by the env." />
>                 <conf name="compile" extends="default,provided" />
>                 <conf name="war" extends="default"/>
>         </configurations>
>         <dependencies>
> ...
>                 <dependency org="log4j" name="log4j" rev="1.2.14+" 
> conf="provided->default"/>
> ... <!-- other deps; indirect depends on log4j 1.2.13 in all my confs. -->
>                 <exclude module="log4j" conf="war"/>
> Now, log4j;1.2.14 is in my compile conf, as I expect it to be.  But 
> log4j;1.2.13 appears in my war conf, which is not what I expect.  I expect 
> there to be no log4j because in this case the environment will provide it 
> (jboss) with its own custom.
