The maven-archetype-webappdoes not generate a src/main/javafolder by default and if you want to add Java sources in your webapp, you need to create src/main/javayourself.
在maven-archetype-webapp不生成src/main/java默认文件夹，如果你想添加的Java源代码在你的web应用，你需要创建src/main/java自己。
Once this directory has been created, right-clickon your project and then use Maven > Update Project Configurationand it will get added as source directory. Then you'll be able to add sources.
创建此目录后，右键单击您的项目，然后使用 Maven > 更新项目配置，它将被添加为源目录。然后你就可以添加源了。
Last thing, either use the maven-eclipse-plugin oruse m2eclipse, not both, they are mutually exclusive.
最后一件事，要么使用 maven-eclipse-plugin要么使用 m2eclipse，不能同时使用，它们是相互排斥的。

It should work. You can mark the folder containing the package as "source folder" in eclipse, but only as a fast solution...
它应该工作。您可以在 eclipse 中将包含包的文件夹标记为“源文件夹”，但只能作为一种快速解决方案......
I usually work with eclipse wihout m2eclipse, and I run mvn eclipse:eclipseto generate the eclipse project. Maybe you can manually fix this running the command now (from eclipse with the plugin or from mvn directly).
我通常在没有m2eclipse的情况下使用eclipse，然后运行mvn eclipse:eclipse生成eclipse项目。也许您现在可以手动修复此运行命令（从带有插件的 eclipse 或直接从 mvn）。
