I need to use Apache Ant to launch Eclipse using Eclipse's org.eclipse.equinox.launcher bundle, but the version may be different, e.g. org.eclipse.equinox.launcher_1.2.0.v20110502.jar. To launch the jar using java task, the exact jar file name must be known. Following Ant script demonstrates how to do that.
<path id="eclipse.launcher.jar.id">
<fileset dir="${eclipse.executable.dir}/plugins">
<include name="org.eclipse.equinox.launcher_*.jar" />
</fileset>
</path>
<property name="eclipse.launcher.jar" refid="eclipse.launcher.jar.id" />
<java jar="${eclipse.launcher.jar}" fork="true" failonerror="true">
</java>
