Question

We use Ant with Ivy and I’d like to embed in our created jars and wars the pom.xml and the pom.properties file just as you see if you used Maven. Creating a pom.xml from the ivy.xml file is pretty simple with the <ivy:makepom> task. Getting the artifactId and the gorupId can be done via the <xmlproperty> task. However, how do I create the pom.properties file. Is that necessary?

Okay, while going through the documentation, I found it was a lot easier than I thought. Ivy generates a lot of properties which can be used. I also found that the pom.xml file only contains the groupId, artifactId and the version, so it’s not that tough to generate.

Here’s what I did:

<target name="package" depends="compile">

    <!-- Make the pom.xml -->
    <ivy:makepom ivyfile="${ivy.resolved.file}"
        pomfile="${target.dir}/pom.xml"/>

    <!-- Make the pom.properties file -->
    <echo file="${target.dir}/pom.properties">
# Generated by Maven NOT!
# ${build.date}
version=${ivy.revision}
groupId="${ivy.organisation}
artifactId="${ivy.module}
    </echo>

<!-- Build your JAR or whatever -->

    <jar destfile="${target.dir}/{ant.project.name}.jar"
         basedir="${main.destdir}">
         <manifest>
              <section name="Build-Information">
                  <attribute name="Project" value="${env.JOB_NAME}"/>
                  <attribute name="Build-Number" value="${env.BUILD_NUMBER}"/>
                  <attribute name="Build-Date" value="${build.date}"/>
              </section>
         </manifest>
         <zipfileset dir="${target.dir}"
              prefix="$META-INF/maven/${ivy.organisation}/${ivy.module}">
              <include name="pom.xml"/>
              <include name="pom.properties"/>
         </zipfileset>
     </jar>
</target>

This helps make using Ivy pretty compatible with Maven.
