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
Either open the project in the IDE and make sure CopyLibs library
exists or setup the property manually. For example like this:
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.
