Error when trying to use optional token in artifacts pattern - ivy

Question

Up until now, I was only generating a dist/imasUtils.jar file in the build (using Ant), and publiching it with the following Ant code:
<ivy:resolve/>
<ivy:publish resolver="imas-ssh" overwrite="true" publishivy="true">
<artifacts pattern="dist/[artifact].[ext]"/>
</ivy:publish>
So far, this worked, but now I want to publish also the source, so I am also generating dist/imasUtils_src.zip. According to my understanding of the ivy manual, I could do this:
<ivy:resolve/>
<ivy:publish resolver="imas-ssh" overwrite="true" publishivy="true">
<artifacts pattern="dist/[artifact](_[type]).[ext]"/>
</ivy:publish>
and that would recognize both of my files dist/imasUtils.jar and dist/imasUtils_src.zip, the only difference is that when I published them the type attribute would be null for the jar file.
Instead, I am getting the following error message:
/[myDirectory]/build.xml:119: impossible to publish artifacts for net.conselldemallorca.imas#imasUtils;1.2.0:
java.io.IOException: missing artifact net.conselldemallorca.imas#imasUtils;1.2.0!imasUtils.jar

My ivy.xml file:

<artifact pattern="http://ivy.proves.imasmallorca.net/Ivy/${artifact.pattern}"/>

</chain>
</resolvers>
</ivysettings>
I am using Apache Ant 1.9.3 and Ivy 2.4.0

I suspect the problem might be the way you've defined the "type" in the pattern. You also need to declare more than one file in your ivy file's publications section.
I suggest the following change to your ivy file:
<ivy-module version="2.0" xmlns:e="http://ant.apache.org/ivy/extra">
<publications>
<artifact name="imasUtils" type="jar"/>
<artifact name="imasUtils" type="zip" e:classifier="src"/>
</publications>
And corresponding change in the publish task's pattern:
<ivy:publish .. >
<artifacts pattern="dist/[artifact](_[classifier]).[ext]"/>
</ivy:publish>
The "classifier" is an example of a custom extra attribute.
Example:
Convert ivy.xml to pom.xml
The following link provides more explanation on how ivy interacts with Maven repos which has a fixed understanding of a "sources" attribute.
