[RESOLVED] The libs.CopyLibs.classpath property is not set up

Hi,

After trying to run some homework exercises I had just finished typing the code for I receive message below in the IDE! Although, my lecturer didn't mention or I have forgotten if he did whether I needed to add any libraries to the project.

J:\5AJA\Sessions\Session9\Session9 Exercises\nbproject\build-impl.xml:460: The libs.CopyLibs.classpath property is not set up.
This property must point to
org-netbeans-modules-java-j2seproject-copylibstask.jar file which is part
of NetBeans IDE installation and is usually located at
<netbeans_installation>/java<version>/ant/extra folder.
Either open the project in the IDE and make sure CopyLibs library
exists or setup the property manually. For example like this:
ant -Dlibs.CopyLibs.classpath=a/path/to/org-netbeans-modules-java-j2seproject-copylibstask.jar
BUILD FAILED (total time: 0 seconds)

I have added both .jar files located in the "/ant/extra folder" directory to the project by both the "Tools > Libraries" menu and by right clicking the "Libraries" folder in the "Projects" windows and clicking "Add Jar/Folder" and adding both .jar files to the project then trying to run it. However, Still receive the above message.

Thanks,
