maven 设置文件编码[WARNING] File encoding has not been set

本文介绍了如何在Maven的不同版本中配置项目的源代码编码方式。对于Maven3,可以在<build>标签内直接指定<sourceEncoding>为UTF-8;而在Maven2中,则需要在<properties>标签内使用<project.build.sourceEncoding>来设置相同的编码。

在maven 3可以做如下配置设置文件编码

<project>

  ...
  <build>

    <!-- NOTE: This is just a vision for the future, it's not yet implemented: see MNG-2216 -->


    <sourceEncoding>
UTF-8</sourceEncoding>

    ...
  </build>

  ...
</project>

 

在maven 2 中采用如下配置

<project>

  ...
  <properties>

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

    ...
  </properties>

  ...
</project>
