Error in generating Javadoc

Looks like a wrong argument has been given to javadoc

I have right clicked on my project and clicked create javadoc. Isn't it netbeans should have passed the argument by itself.

Anyway What arguments should I pass and where?

Please guide me with the command.

Thanks for your help

>>Isn't it netbeans should have passed the argument by itself.

Yes that's right. Perhaps somehow it passed a bad one. Try invoking it from the command line

check the build file to find the setting it does not like

Ok, I will try generating from command line as well.

What is the command using command line

Yes, my build.xml file content is below. Please see and help if you can find something in here

Many Thanks for your help and co-operation

    There exist several targets which are by default empty and which can be 
    used for execution of your tasks. These targets are usually executed 
    before and after some main targets. They are: 
 
      -pre-init:                 called before initialization of project properties
      -post-init:                called after initialization of project properties
      -pre-compile:              called before javac compilation
      -post-compile:             called after javac compilation
      -pre-compile-single:       called before javac compilation of single file
      -post-compile-single:      called after javac compilation of single file
      -pre-compile-test:         called before javac compilation of JUnit tests
      -post-compile-test:        called after javac compilation of JUnit tests
      -pre-compile-test-single:  called before javac compilation of single JUnit test
      -post-compile-test-single: called after javac compilation of single JUunit test
      -pre-jar:                  called before JAR building
      -post-jar:                 called after JAR building
      -post-clean:               called after cleaning build products
 
    (Targets beginning with '-' are not intended to be called on their own.)
 
    Example of inserting an obfuscator after compilation could look like this:
 
        <target name="-post-compile">
            <obfuscate>
                <fileset dir="${build.classes.dir}"/>
            </obfuscate>
        </target>
 
    For list of available properties check the imported 
    nbproject/build-impl.xml file. 
 
 
    Another way to customize the build is by overriding existing main targets.
    The targets of interest are: 
 
      -init-macrodef-javac:     defines macro for javac compilation
      -init-macrodef-junit:     defines macro for junit execution
      -init-macrodef-debug:     defines macro for class debugging
      -init-macrodef-java:      defines macro for class execution
      -do-jar-with-manifest:    JAR building (if you are using a manifest)
      -do-jar-without-manifest: JAR building (if you are not using a manifest)
      run:                      execution of project 
      -javadoc-build:           Javadoc generation
      test-report:              JUnit report generation
 
    An example of overriding the target for project execution could look like this:
 
        <target name="run" depends="compNewsletterMailMerge-impl.jar">
            <exec dir="bin" executable="launcher.exe">
                <arg file="${dist.jar}"/>
            </exec>
        </target>
 
    Notice that the overridden target depends on the jar target and not only on 
    the compile target as the regular run target does. Again, for a list of available 
    properties which you can use, check the target you are overriding in the
    nbproject/build-impl.xml file.

>>Yes, my build.xml file content is below.

build.xml is of lesser importance in NetBeans. We need build-impl.xml

Thanks for your help

Please find the file: build-impl.xml

Yes, My main class file name is: NewsletterMain
I have renamed this file from Main to NewsletterMain some time ago
