Body:
Ant versions: don't know. The one in IntelliJ 4.0.3 and the one provided with Maven.
I tried to escape IntelliJ's ant version with the following code, in order to use the
ant version inside maven. No difference.
First fork new ant in new java VM:
<target name="site" >
<java fork="true" classname="org.apache.tools.ant.Main" >
<classpath>
<fileset dir="${maven.dir}/lib">
<include name="**/*.jar"/>
</fileset>
</classpath>
<arg value="-f"/><arg value="ant-space2.xml" />
<arg value="site-impl" />
</java>
</target>
And then start maven from there:
<target name="site-impl">
<taskdef name="maven"
classname="org.apache.maven.ant.MavenTask">
<classpath>
<fileset dir="${maven.dir}/lib">
<include name="**/*.jar"/>
</fileset>
</classpath>
</taskdef>
<maven mavenHome="${maven.dir}"
goalName="multiproject:site"
projectBuildFile="maven.xml"
projectFileName="project.xml"
toolsJar="${java.home}/lib/tools.jar"
/>
</target>

Description:
Starting maven from an ant script is the simplest (and only?) way to integrate Maven
with the IDEs that have ant support. However, I get a ClassCastException during the
initialisation of the Maven core:

The goal executes normally when maven is started on the command line
