我刚刚开始尝试在 Android 平台上运行的 I-Jetty 服务器。首先，我尝试使用来自 org.apache.maven.archetypes 的 Maven 原型“maven-archetype-webapp”创建一个简单的 Web 应用程序，我想在 I-Jetty 上对其进行测试。这会产生一个最小的 maven 项目，其中包含一个名为 index.jsp 的简单 jsp 文件，如下所示。
<html>
<body>
<h2>Hello!</h2>
</body>
</html>
当将此 web 应用程序导出为战争并部署到 I-Jetty 时，我从 I-Jetty 获得“不支持 jsp”。做了一些研究，我发现我必须预编译 JSP，因为 I-Jetty 没有 JSP 编译器。这就是问题所在。我正在尝试使用名为 jetty-jspc-maven-plugin 的预编译插件。我正在使用带有 m2e 插件的 Eclipse Kepler。
我已经搜索了不同的方法来处理预编译 jsps，结果是这个 pom；

将项目作为 maven install 运行时，项目已成功构建，但似乎我的 jetty-jspc-maven-plugin 在构建中完全被忽略了：

但是在包含 jspc 插件之后，我什至没有得到错误代码或任何东西。作为 maven 的新手，我向一位经验丰富的 maven 用户寻求一些关于忽略 jetty-jspc-maven-plugin 的帮助。是构建周期问题吗？Eclipse 或 m2e 是否出于某种原因默默地忽略了这个插件？如您所见，maven-war-plugin 已执行，因此似乎并非所有插件都被忽略。
这是我在 Stackoverflow 上发布的第一个问题，所以如果我遗漏了关于这篇文章的任何信息，请原谅我。
