执行Maven Install打包的时候，提示以下警告信息： 

[WARNING] Using platform encoding (GBK actually) to copy filtered resources, i.e. build is platform dependent!

解决方法：
打开项目属性》Resources，按下图修改。

保存后重新执行Maven Install 发现警告依然存在，原来是理解错误错误了，应该修改Maven的配置文件中关于编码的配置<encoding>utf-8</encoding>：
完整示例：

<code class="hljs xml has-numbering"><span style="font-size:24px;">            <span class="hljs-tag"><<span class="hljs-title">plugin</span>></span>                <span class="hljs-tag"><<span class="hljs-title">groupId</span>></span>org.apache.maven.plugins<span class="hljs-tag"></<span class="hljs-title">groupId</span>></span>                <span class="hljs-tag"><<span class="hljs-title">artifactId</span>></span>maven-compiler-plugin<span class="hljs-tag"></<span class="hljs-title">artifactId</span>></span>                <span class="hljs-tag"><<span class="hljs-title">version</span>></span>3.0<span class="hljs-tag"></<span class="hljs-title">version</span>></span>                <span class="hljs-tag"><<span class="hljs-title">configuration</span>></span>                    <span class="hljs-tag"><<span class="hljs-title">encoding</span>></span>utf-8<span class="hljs-tag"></<span class="hljs-title">encoding</span>></span>                    <span class="hljs-tag"><<span class="hljs-title">source</span>></span>1.8<span class="hljs-tag"></<span class="hljs-title">source</span>></span>                    <span class="hljs-tag"><<span class="hljs-title">target</span>></span>1.8<span class="hljs-tag"></<span class="hljs-title">target</span>></span>                <span class="hljs-tag"></<span class="hljs-title">configuration</span>></span>            <span class="hljs-tag"></<span class="hljs-title">plugin</span></span></span></code>

还是存在警告，原来是需要在<project>中添加<properties>标签：

<code class="hljs xml has-numbering"><span style="font-size:24px;"><span class="hljs-tag"><<span class="hljs-title">properties</span>></span>         <span class="hljs-tag"><<span class="hljs-title">project.build.sourceEncoding</span>></span>             UTF-8         <span class="hljs-tag"></<span class="hljs-title">project.build.sourceEncoding</span>></span><span class="hljs-tag"></<span class="hljs-title">properties</span>></span></span></code>
