Java SE (Java Platform, Standard Edition)

Hello again!
I just update javaFx to build 42, and i have troubles when i try to build the application in netbeans to make the .html, .jar and .jnlp files.

This is the error:

C:\Users\sam\Documents\NetBeansProjects\Ejemplos\nbproject\jfx-impl.xml:23: fxjar doesn't support the "applicationClass" attribute BUILD FAILED


And this is the jfx-impl.xml

 
<?xml version="1.0" encoding="UTF-8"?>
<project name="jfx-impl" default="jfx-deployment" basedir="..">
   
   <target name="check-jfx-deployment">
        <condition property="jfx-deployment-available">
            <typefound name="fxjar"/>
        </condition>
   </target>
   
   <target name="jfx-deployment" depends="check-jfx-deployment" if="jfx-deployment-available">
        <!-- settings default width and height values -->
        <property name="jfx.applet.width" value="800"/>
        <property name="jfx.applet.height" value="600"/>
        
        <basename property="jfx.deployment.jar" file="${dist.jar}"/>
        <property name="jfx.deployment.dir" location="${dist.dir}"/>      
        <!-- hack for beta: remove the just generated standard non-fx deployment files to be replaced by the fx ones -->
        <delete file="${jfx.deployment.dir}/${jfx.deployment.jar}"/>
        <delete file="${jfx.deployment.dir}/README.TXT"/>
        <!-- hack end -->

        <fxjar destfile="${jfx.deployment.dir}/${jfx.deployment.jar}"
             applicationClass="${main.class}" >
            <fileset dir="${build.classes.dir}"/>
            <manifest>
              <attribute name="Implementation-Vendor" value="${application.vendor}"/>
              <attribute name="Implementation-Title" value="${application.title}"/>
              <attribute name="Implementation-Version" value="1.0"/>
            </manifest>
        </fxjar>

        <fxdeploy width="${jfx.applet.width}" height="${jfx.applet.height}"
                  outdir="${jfx.deployment.dir}" embedJNLP="true"
                  outfile="${application.title}">
            <info title="${application.title}"
                  vendor="${application.vendor}"/>
            <application name="${application.title}"
                         appclass="${main.class}"/>
            <resources type="eager">
               <fileset dir="${jfx.deployment.dir}">
                  <include name="${jfx.deployment.jar}"/>
                  <include name="lib/*.jar"/>
                  <exclude name="**/jfxrt.jar"/>
               </fileset>
            </resources>
        </fxdeploy>  
    </target>
    
</project>

Can somebody help me to fix this please.
