java - NetBeans 找不到我的类

Question

Netbeans 返回 NoClassDefFoundError，但我的类就在那里!以前有人发生过这种情况吗？问题已解决:我的类前面有一个错误的注释，因此运行时没有识别它。

run:
java.lang.NoClassDefFoundError: targzipmanager/TarGzipManagerView
Caused by: java.lang.ClassNotFoundException: targzipmanager.TarGzipManagerView
        at java.net.URLClassLoader$1.run(URLClassLoader.java:202)
        at java.security.AccessController.doPrivileged(Native Method)
