bad name in value for --add-modules when trying to compile through ant

Question

I am trying to include the javafx.controls module in my project and compile it through ant, rather then use javaFX javac --module-path "..\lib\javafx-sdk-17.0.2\lib" --add-modules javafx.controls App.java

java --module-path "..\lib\javafx-sdk-17.0.2\lib" --add-modules javafx.controls App commands to compile the file(s).

This is how my ant build.xml looks like right now:

<project name="projectName" default="dist">
    <property file="build.properties"/>
    <property file="${user.home}/build.properties"/>

    <path id="run.classpath">
        <fileset dir="${dist.dir}">
            <include name="${project.name}.jar"/>
        </fileset>
    </path>

    <target name="compile">
        <mkdir dir="${build.dir}"/>
        <javac srcdir="${src.dir}"
               destdir="${build.dir}"
               debug="${compile.debug}"
               deprecation="${compile.deprecation}"
               optimize="${compile.optimize}"
               includeantruntime="false">
                <classpath>
                    <fileset dir="${lib.dir}/javafx-sdk-17.0.2/lib">
                        <include name="**/*.jar" />
                    </fileset>
                </classpath>
                <compilerarg line="--add-modules ${lib.dir}/javafx-sdk-17.0.2/lib/javafx.controls"/>
        </javac>
    </target>

    <target name="dist" depends="compile">
        <mkdir dir="${dist.dir}"/>
        <jar jarfile="${dist.dir}/${project.name}.jar"
             basedir="${build.dir}"
             manifest="${src.dir}/Manifest.mf">
             <zipgroupfileset dir="${lib.dir}/javafx-sdk-17.0.2/lib" includes="**/*.jar"/>
        </jar>
    </target>

    <target name="build" depends="dist">
        <java jar="${dist.dir}/${project.name}.jar" fork="true">
        </java>
    </target>

    <target name="clean">
        <delete dir="${build.dir}"/>
        <delete dir="${dist.dir}"/>
    </target>
</project>

The error I keep on getting is: error: bad name in value for --add-modules option: 'C:\xampp\htdocs\projectName/lib/javafx-sdk-17.0.2/lib/javafx.controls'. I have looked up the error, but the answers are very vague in my opinion and have not helped me get more knowledge in regards to the error.
