Maven似乎正在忽略Webapp中的源和目標

Question

我收到“ -source 1.5中不支持生成的servlet錯誤：| try-with-resources”。 根據該主題的另一個問題，1.5是maven的默認設置，但我認為我已經在pom.xml中修復了該問題-

<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"

如父pom所示，項目中的其他軟件包在1.7上都可以正常工作-

</project>

最終，我認為問題可能是“ Maven忽略了源和目標規范，我做錯了什么？” 那里也有類似的問題，但是我所看到的問題要么沒有解決，要么暗示我pom中存在的問題。

任何幫助，將不勝感激。

Jetty默認使用1.5源和目標args進行JSP編譯。 看到Jetty嵌入式和JSP編譯到1.7嗎？ 有關將Jetty切換為使用1.7的指針和信息
