我正在关注https://javaee.github.io/firstcup/creating-example002.html中的 dukes-age 示例应用程序，但在尝试构建 dukes-age.war 时遇到了问题。
构建时收到的错误是：
Failed to execute goal from com.blazebit:jbake-maven-plugin:1.0.0:build (build-site) on project dukes-age: Failure when running: Error: Source folder must exist: ... -> [Help 1]
我已将 pom.xml 文件更改如下：

我究竟做错了什么？
非常感谢
