Question

我尝试使用Java和Jetty实现一个简单的聊天应用程序。我已经遵循了下面博客文章给出的所有步骤。

博客文章

当我尝试运行 mvn jetty：run 时，出现以下错误：

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:2.0.2:compile (default-compile) on project sample_application: Compilation failure

我已经分享了我在下面使用的Java和Maven版本：

• Apache Maven 3.0.5

• Maven home：/usr/share/maven

• Java版本：1.7.0_03，供应商：甲骨文公司

• Java home：/usr/local/jdk1.7.0_03/jre

• 默认区域设置：en_US，平台编码：UTF-8

• 操作系统名称： "linux"， 版本： "3.13.0-76-通用"， arch： "amd64"，家庭："优尼克斯">

在这里你可以找到pom.xml下面。

谁能帮我找出出了什么问题？

附言 - 我正在使用 IntelliJ Idea 14.1.3

根据要求，我分享了更新pom时遇到的错误.xml如回答中所述。

Answer 1

您收到此错误是因为 Maven 默认使用 JDK1.3 进行项目编译或构建。由于 JDK1.3 不支持注释，因此如果您的项目具有注释，则需要将 Maven 配置为使用最新的 JDK 版本。

如上所述，您需要告诉 maven 运行您拥有的最新版本的 JDK。
