Error when creating JavaFX jar file from codes written in Groovy - javafx

Question

I tried to create a standalone jar file from source codes written in Groovy, using the following build.xml:
<?xml version="1.0" encoding="UTF-8"?>
<project name="build" default="build" basedir="." xmlns:fx="javafx:com.sun.javafx.tools.ant">
<property name="groovy" value="C:/groovy-2.4.5"/>
<property name="source" value="source"/>
<property name="binary" value="binary"/>
<property name="distribution" value="distribution"/>
<property name="data" value="data"/>
<property name="name" value="application"/>
<property name="class" value="ziphil.main.Launcher"/>
<path id="groovy.classpath">
<fileset dir="${groovy}/embeddable/"/>
</path>
<path id="compile.class.path">
<fileset dir="${groovy}/lib/"/>
</path>
<taskdef name="groovyc" classname="org.codehaus.groovy.ant.Groovyc" classpathref="groovy.classpath"/>
<target name="clean">
<mkdir dir="${binary}"/>
<mkdir dir="${distribution}"/>
<delete>
<fileset dir="${binary}" includes="**/*"/>
<fileset dir="${distribution}" includes="**/*"/>
</delete>
</target>
<target name="compile" depends="clean">
<groovyc srcdir="${source}" destdir="${binary}" classpathref="compile.class.path" encoding="UTF-8"/>
<copy todir="${binary}/${data}">
<fileset dir="${source}/${data}"/>
</copy>
</target>
<target name="build" depends="compile">
<taskdef resource="com/sun/javafx/tools/ant/antlib.xml" uri="javafx:com.sun.javafx.tools.ant" classpath="${java}/lib/ant-javafx.jar"/>
<fx:application id="id" name="${name}" mainClass="${class}"/>
<fx:resources id="appRes">
<fx:fileset dir="${distribution}" includes="${name}.jar"/>
</fx:resources>
<fx:jar destfile="${distribution}/${name}.jar">
<fx:application refid="id"/>
<fx:resources refid="appRes"/>
<fileset dir="${binary}"/>
</fx:jar>
</target>
<target name="run" depends="build">
<java jar="${distribution}/${name}.jar" fork="true"/>
</target>
</project>
But I had an error saying that the main class was not found when trying to run the created jar file (in run target of the XML above). What should I do to resolve this error?

You may have to add to the runtime classpath all the jars that your application depends on. I guess that you need at least to include compile.class.path to your runtime classpath :
<target name="run" depends="build">
<java jar="${distribution}/${name}.jar" fork="true" classpathref="compile.class.path"/>
</target>
