<h2 id="clonevm">ant.build.clonevm</h2>

<p><em>Since Apache Ant 1.7</em></p>

<p>The value of the <code>ant.build.clonevm</code> system property
controls how Ant instruments forked JVMs.  The <a href="Tasks/java.html">java</a>
and <a href="Tasks/junit.html">junit</a> tasks support <var>clonevm</var>
attributes to control JVMs on a task-by-task basis while the system
property applies to all forked JVMs.</p>

<p>If the value of the property is <q>true</q>, then all system properties of
the forked JVM will be the same as those of the JVM running Ant. In
addition, if you set <code>ant.build.clonevm</code> to <q>true</q>
and <a href="sysclasspath.html">build.sysclasspath</a> has not been
set, the <var>bootclasspath</var> of forked JVMs gets constructed as
if <code>build.sysclasspath</code> had the value <q>last</q>.</p>

<p>Note that this has to be a system property, so it cannot be
specified on the Ant command line.  Use the <code>ANT_OPTS</code>
environment variable instead.</p>
