编译字符编码警告

问题

运行 mvn compile
控制台输出

[WARNING] File encoding has not been set, using platform encoding GBK, i.e. build is platform dependent!

处理方法

在 pom.xml 文件中添加 properties 标签

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