non-optimal ivy exclusion xml

[Eric Bowman]

I'm trying to prevent depending on jerkson, from doing an expensive "version range query" using ivy.

In my 0.12.0 project, I'm declaring the dependency on jerkson like:

"com.codahale" %% "jerkson" % "0.5.0" excludeAll(
  ExclusionRule(organization = "org.codehaus.jackson")
),

The generates ivy.xml like:

<dependency org="com.codahale" name="jerkson_2.9.1" rev="0.5.0" conf="compile->default(compile)">
    <exclude org="org.codehaus.jackson" module="*" name="*" type="jar" ext="*" conf="" matcher="exact"/>
</dependency>

I'm building a library which an ant + ivy build depend on, and this ivy xml doesn't stop ivy from doing the expensive resolve.

However if I hand-modify the ivy xml to look like:

<dependency org="com.codahale" name="jerkson_2.9.1" rev="0.5.0" conf="compile->default(compile)">
    <exclude org="org.codehaus.jackson"/>
</dependency>

...the right stuff happens (ant+ivy builds go fast).

Is it possible to get sbt 12 to generate ivy xml like this?

Thanks,

Eric

This will probably be fixed by:

https://github.com/harrah/xsbt/commit/dfac015eb34d41e9ef44db0679d470d143798cac

which will go in 0.12.1. (This release should be binary and source compatible with 0.12.0 and I expect the release process for it to begin soon.)
