maven 处理 [WARNING] Using platform encoding (GBK actually) to copy filtered resources 的警告

一、问题描述

使用 mvn package 打包项目的时候,总是输出如下警告:

[INFO] --- maven-resources-plugin:2.6:resources (default-resources) @ test ---
[WARNING] Using platform encoding (GBK actually) to copy filtered resources, i.e. build is platform dependent!

[INFO] --- maven-resources-plugin:2.6:testResources (default-testResources) @ test ---
[WARNING] Using platform encoding (GBK actually) to copy filtered resources, i.e. build is platform dependent!

二、解决方式

方式一

在maven项目的pom.xml中添加如下配置

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

保存后我们再运行,发现之前的警告不见了。

查看 spring-boot-starter-parent.pom 文件,可以在 <properties> 中有如下配置:

所以如果项目继承自 spring-boot-starter-parent 默认情况下就已经添加
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>

方式二

我们可以在 maven 对应的插件中设置编码,可以通过如下方式 设置:

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-resources-plugin</artifactId>
            <version>3.2.0</version>
            <configuration>
                <encoding>UTF-8</encoding>
            </configuration>
        </plugin>
    </plugins>
</build>
