调用类org.jboss.resteasy.cdi.cdiinjectorFactory放置在多个bean存档中

Question

这个问题以前在stackoverflow上被问过，但没有作为帖子的主要问题出现。这是一个次要的问题。这就是为什么我在一个新的讨论中问它。目的是要有更好的回答率。在发布这个问题之前，我问了stackoverflow一个建议

我尝试用jetty 9.4.8运行一个应用程序的部署。它是一个角java maven多模块应用程序

当我运行jetty来部署我的war时，我会出现以下错误。我在网上深入搜索，但没有找到解决办法

这可能只是配置问题。

这是触发错误的代码...

https://github.com/weld/core/blob/6c2b09fac4e694a20877f017424acd6c4b3e3439/impl/src/main/java/org/jboss/weld/simplecdi.java#L50-L71

在代码中的for循环中放置一个断点，这样您就可以调试并查看它从哪里提取这些Bean管理器。
