我使用的是primefaces 5.3版本，它运行良好，但我不得不将其升级到6.0版本以使用更多组件。
很多错误开始发生，我回到5.3，但更多的错误开始发生。我认为我的应用程序中有一些错误，因为我同时做了一些更改，但后来我尝试将primefaces依赖关系升级到上一个6.2版本，许多错误停止了，我回到6.0版本，发生了更多的错误，比我第一次从5.3改为6.0时更多的错误。
我相信素数面在我的代码和它的版本中改变了更多的东西。
这是在我使用5.3版本时发生的错误：

不知怎么地我修复了这个错误，我不知道是怎么修复的，但我确实修复了。我简单地删除了.m2目录(先保存了一个副本(，然后让netbeans再次创建它。
不幸的是，它工作不太好，然后我删除了这个新的.m2目录，并返回到我保存的副本。
它开始发挥作用。
就像我说的，我不知道为什么会发生这种事。
