How is this working with Ivy?  AFAIK this is broken in Ivy.

Not that I know off. What exactly do you mean is broken? The whole Ivy  
exclude mechanism?

Hi Rafa,

I can't reproduce this. The following code works for me (MetaModel  
has a
dependency on hsqldb):

usePlugin 'java'

repositories {
       mavenCentral()
}

configurations {
 all*.exclude group: "hsqldb"
}

dependencies {
       compile "dk.eobjects.commons:MetaModel:1.0.7"
}

task myTask << {
       configurations.testRuntime.each { file -> println file }
}

P.S. You don't need to quote the task name any more when creating it.

Could you create a test case and file a Jira?

Hi all,

I am currently migrating from 0.5 to 0.6 and have almost succeeded  
(thanks
to the breaking changes doc) except for the exclusion of transitive
dependencies. Actually, I'm getting a NPE when I try to iterate  
over the
files in a configuration.

Here is a code snippet:
configurations {
 all*.exclude group: "hsqldb"
}
dependencies {
 compile "a-jar-that-depends-on-hsqldb"
}
task "myTask" << {
       configurations.testRuntime.each { file -> println file }
}

Is this really a bug or am I doing something wrong? In case it is  
a bug,
could you please think of a workaround?

Thanks in advance. Regards
Rafa
