我收到“生成的 servlet 错误：|-source 1.5 不支持 try-with-resources”。根据关于该主题的另一个问题，1.5 是 maven 的默认值，但我认为我已经在我的 pom.xml 中修复了它 -

<project xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd" xmlns="http://maven.apache.org/POM/4.0.0"

项目中的其他包在 1.7 中可以正常工作，如父 pom 中所示 -

</project>

最终，我认为问题可能是“我做错了什么，maven 忽略了源和目标规范？” 那里有类似的问题，但我看到的问题要么没有解决，要么提出了我的 pom.xml 中存在的问题。

任何帮助，将不胜感激。

默认情况下，Jetty 使用 1.5 源和目标参数进行 JSP 编译。看到Jetty 嵌入和 JSP 编译到 1.7？有关将 Jetty 切换为使用 1.7 的指针和信息
