NetBeans Web 应用程序

Question

我正在开发一个使用休眠模式的 NetBeans WebApplication。更改两行代码后出现下一个错误：

ant -f C:\Users\User\Assignments\AssignmentZaposleni -Dnb.internal.action.name=debug -Ddirectory.deployment.supported=true -DforceRedeploy=false -Dnb.wait.for.caches=true -Dbrowser.context=C:\Users\User\Assignments\AssignmentZaposleni debug
C:\Users\User\Assignments\AssignmentZaposleni\nbproject\build-impl.xml:797: 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)

之前改代码编译没问题。代码的变化是：

之前的代码：

mySQL=Restrictions.sqlRestriction(upit.substring(upit.indexOf("WHERE")));
    criteria.add(mySQL);

后面的代码：

mySQL=Restrictions.sqlRestriction(upit.substring(upit.indexOf("WHERE")));
    criteria.add(mySQL);
List list =session.createCriteria(Zaposleni.class).add(mySQL).list();

当我评论更改错误仍然存在！？有人可以帮我弄这个吗？谢谢

也许您有自动 NetBeans 更新，并且在您更改 Java 代码期间，NetBeans 进行了一些更新并更改了配置文件。也许试试这个，它可能会有所帮助：

鼠标右键单击项目name/Properties/Libraries/Compile/

如果没有"CopyLibs Task"按添加：

AddLibrary，select CopyLib 任务，最后 AddLibrary/OK。
