I had the same issue. The problem occurs, when mvn-init target will be called twice. You can solve it using the "unless" attribute. For example:

<target name="mvn-init" unless="mvn-init.called">
    <path id="maven-ant-tasks.classpath" path="maven-ant-tasks-2.1.1.jar"/>
    <typedef resource="org/apache/maven/artifact/ant/antlib.xml" uri="antlib:org.apache.maven.artifact.ant" classpathref="maven-ant-tasks.classpath"/>
    <artifact:dependencies pathId="application.jars" filesetId="dependency.fileset" versionsId="dependency.versions">
        <dependency groupId="javax.servlet" artifactId="servlet-api" version="2.4" scope="provided"/>
    </artifact:dependencies>
    
    <property name="mvn-init.called" value="true" />
</target>

<target name="test" depends="mvn-init"></target>
<target name="test2" depends="mvn-init"></target>
