【问题描述】：

我不知道为什么并且已经阅读了很多关于此的文章。但是我将与设置java版本相关的每个部分都设置为1.7。

但还是会报错

这是我的 Maven 日志

Apache Maven 3.2.2 (45f7c06d68e745d05611f7fd14efb6594181933e; 2014-06-17T22:51:42+09:00)

并且我将这个项目的 jre 系统库设置为 java 7。

更新

我添加了 pom.xml 中最相关的部分

【问题讨论】：

您能否提供有关您的 pom 文件的更多信息？
谢谢。 @Rodolfo 我要添加 pom 文件的哪一部分？ :D
你试过 mvn clean 吗？？
@IkerAguayo 当然！！我一直在运行 mvn clean install
好的。您是否尝试将版本设置为 maven-compiler-plugin。尝试使用 3.x 版本，然后尝试使用 2.x，如果它不起作用等。丢弃东西

标签： maven maven-2 maven-plugin

【解决方案1】：

我不知道你的pom有没有sourceEncoding属性，虽然你把编码配置放在maven.complier.plugin里，但是我用sourceEncoding指定到属性maven部分。

<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>

你的 maven 错误输出抱怨 \65279 字符，here 你可以找到这个字符的含义和一些解释。也许您必须使用另一个文本编辑器。
