我使用的是primefaces 5.3版，但工作正常，但必须将其升级到6.0版才能使用更多组件。
许多错误开始发生，我回到5.3，但更多错误开始发生。尽管在此期间我做了一些更改，但我的应用程序中出现了一些错误，但是后来我尝试将primefaces依赖关系升级到最新版本6.2，许多错误停止发生，而我又回到了6.0版，发生了更多错误，更多错误比我第一次从5.3更改为6.0。
我相信素字对我的代码和版本的影响更大。
这是所有这些混乱之后我在5.3版时发生的错误：

最佳答案
我以某种方式解决了该错误，但我不完全知道该怎么做，但我确实做到了。我简单地删除了（首先保存一个副本）.m2目录，然后让netbeans再次创建它。
不幸的是，它不能很好地工作，然后我删除了这个新的.m2目录，并返回到我保存的副本。
它开始起作用。
就像我说的那样，我不知道为什么会这样。
