Jetty 中的 CDI 无效 bean 存档扫描（不在 Tomcat 中）
CDI invalid bean archive scanning in Jetty (not in Tomcat)
我以为我对 Weld 和 CDI 了解得最多，但这个假设总是被证明是错误的。这次我遇到了一个关于 bean 扫描的奇怪行为。一切（多模块 Maven 项目）在 Tomcat 中运行良好，但在 Maven Jetty 9 插件中运行时出现问题：

我搜索了很多，但找不到关于此错误的太多信息。可悲的是，我什至可以分享这个项目的糟糕之处。看起来 Jetty 扫描了两次 bean，这可能吗？任何 help/tip 关于此错误可能是什么以及如何追踪它的任何信息？

jetty-maven-plugin版本为9.4.6.v20170531。 webapp 是一个简单的webapp。它在激活 cdi 模块的 Jetty 9.4.6 上部署良好。

我阅读 this 并将 weld-servlet 工件添加为插件的依赖项：

web.xml 不需要任何更改，但我面临相同的结果（焊接 servlet 版本与 jetty 的 cdi 模块目录中的 jar 版本匹配）。
Maven Jetty 插件有不少问题（主要是奇怪的类加载问题）。该插件甚至已从 Weld 示例中删除。
这个错误基本上意味着 Weld 找到了多个引用同一个 beans.xml.
的 bean 档案
我相信如果将您的应用程序部署到独立的 Jetty 上，它会运行良好。复制器应用程序或至少一些配置信息（Weld 版本、Jetty 版本等）和 deploymnet 结构也会有所帮助。
