Ant can't seem to link to groovy properly in NetBeans 8.2 - netbeans

Question

In netBeans 8.2, I'm having an issue reading groovy inside a build.xml file.
I have a project in which I run my script via a build.xml using the build-in Ant 1.9.7.
In it, for my groovy task, I set the following:
<property environment="env" />
<path id="groovy.classpath">
<fileset dir="${env.GROOVY_HOME}/embeddable" />
</path>
<taskdef name="groovy" classname="org.codehaus.groovy.ant.Groovy" classpathref="groovy.classpath" />
For environment variable {env.GROOVY_HOME}, I have set the following in windows environment variable:
GROOVY_HOME with the value C:\Program Files (x86)\Groovy\Groovy-2.4.10
Yet I'm still having an error ""Script failed" when reaching the step with Groovy at the following stage in the build.xml file:
<groovy>
def corePlatformList = []
[Groovy code here...]
</groovy>
I know the script is working fine as it does run perfectly in Eclipse and IntelliJ.
It would seem ant can't link with Groovy 2.4.10 for some reason.

I believe that you have some trivial error.
You need to include the library file.
Change from:
<path id="groovy.classpath">
<fileset dir="${env.GROOVY_HOME}/embeddable" />
</path>
To:
<path id="groovy.classpath">
<fileset dir="${env.GROOVY_HOME}/embeddable">
<include name="**/groovy-all-*.jar"/>
</fileset>
</path>
EDIT: based on OP comments
Here is the complete build.xml and I can see it working.
<project name="MyProject" default="runscript" basedir=".">
<path id="groovy.classpath">
<fileset dir="d:/softwares/groovy-2.4.5/embeddable">
<include name="**/groovy-all-*.jar"/>
</fileset>
</path>
<taskdef name="groovy" classname="org.codehaus.groovy.ant.Groovy" classpathref="groovy.classpath" />
<target name="runscript"
description="compile the source">
<groovy>
def corePlatformList = [1,2,3,4]
println corePlatformList
</groovy>
</target>
</project>
