title: The libs.CopyLibs.classpath property is not set in Netbeans 8.0
body: <p>My Java EE project was running normally in NetBeans 8.0 and Glassfish 4.0. </p>
  
  <p>After rebooting my notebook, I started the server, the IDE and then tried to run the project again. I got a "The libs.CopyLibs.classpath property is not set" message and googled to find a solution. </p>
  
  <p>Many answers talk about Tools > Options > Miscellaneous > Ant. But my NetBeans does not have an Ant tab in Miscellaneous, but in Java. </p>
  
  <p>I don't know if there is any difference, I am new on this. Even adding the property "libs.CopyLibs.classpath=/java/ant/extra/org-netbeans-modules-java-j2seproject-copylibstask.jar" on Java > Ant the project don't build. By adding this many other errors appear.</p>
