Subject RE: Compiling/storing for multiple arch.
Date Mon, 19 Mar 2012 18:08:26 GMT
I ended up coming my own solution that I think works well enough.

I used extended attirbutes in the ivy.xml to specify what platform I'm on:

<info organisation="org" module="${ant.project.name}" revision="${version}" e:platform="${platform}"/>

When we go to resolve though, the ivy.xml file gets overwritten, so I created ivy.xml.orig,
and passed that to the ivy:resvole when i needed to:

<ivy:resolve file="ivy.xml.orig" />

Then when I create a dependency, I specify the extra attribute:
<dependency name="libCommon" rev="trunk" e:platform="${platform}" />

(again, I must use a separate ivy.xml file, otherwise it'll get over written..)

I also modified the paths of the resovler to account for the platform:
        <ivy pattern="${user.home}/.ivy2/local/[organisation]/[module]/[platform]/ivys/ivy-[revision].xml"/>
        <artifact pattern="${user.home}/.ivy2/local/[organisation]/[module]/[platform]/[type]s/[artifact].[ext]"/>


This seems to be working well enough for me.. It means that I have to use the extra ivy.xml.orig
file, but thats ok I guess.
