Question

是否可以在使用嵌入式jetty服务器项目创建的超级jar中存储静态资源？我根据@JoakimErdfelt Serving static files from alternate path in embedded Jetty的答案创建了这个简单的项目。我保留了default-servlet以提供静态内容，但我将dynamic-servlet切换为restful jersey-servlet，只要jar与index.html位于同一目录下，它就能正常工作。我希望能够将index.html文件嵌入jar中，但是当我发出＆＃34; mvn clean install＆＃34; webapp目录不会出现在构建的jar中。我认为pom.xml需要一个条目，但我不知道它是什么，我认为jetty.java需要更改以在嵌入式webapp目录中找到index.html。这是当前的目录结构。

        // It is important that this is last.
