我正在尝试按照http://www.baeldung.com/maven-minification-of-js-and-css-assets中的说明在我的Spring MVC Web应用程序中使用YUI压缩器maven插件。我已将以下内容添加到pom.xml文件中：
<plugin>
<groupId>net.alchim31.maven</groupId>
<artifactId>yuicompressor-maven-plugin</artifactId>
<version>1.5.1</version>
<executions>
<execution>
<goals>
<goal>compress</goal>
</goals>
</execution>
</executions>
<configuration>
<nosuffix>true</nosuffix>
<webappDirectory>${project.build.directory}/min</webappDirectory>
<excludes>
<exclude>**/*.min.js</exclude>
<exclude>**/handlebars-3133af2.js</exclude>
<exclude>**/require.js</exclude>
</excludes>
</configuration>
</plugin>
我在src/main/webapp下的子文件夹中有很多CSS和JS文件，根据文档，所有这些都应该缩小。但是当我运行maven clean install时，我在控制台中看不到任何与缩小相关的日志，也没有在war文件中找到任何缩小的文件。
我想要的只是将缩小的文件保存在名为min的子文件夹下，文件名与现有的CSS或JS文件位于同一文件夹中
控制台日志现在是：

如果您在pom.xml中没有nosuffix选项运行，就像您发布的配置一样，您将在target \ min文件夹中获得最小化的文件。您将在下面看到登录maven

当您使用<nosuffix>true</nosuffix>时，您将获得以下日志。此选项将为您提供target \ min文件夹中的缩小文件，但会保持文件名相同。

要在战争中包含这些最小化文件而不是原始文件，您需要在pom.xml中设置<webappDirectory>。所以你的配置应该如下所示
<plugin>
<groupId>net.alchim31.maven</groupId>
<artifactId>yuicompressor-maven-plugin</artifactId>
<version>${yuicompressor-maven-plugin.version}</version>
<executions>
<execution>
<goals>
<goal>compress</goal>
</goals>
</execution>
</executions>
<configuration>
<nosuffix>true</nosuffix>
<webappDirectory>${project.build.directory}/min</webappDirectory>
<excludes>
<exclude>**/*.min.js</exclude>
<exclude>**/handlebars-3133af2.js</exclude>
<exclude>**/require.js</exclude>
</excludes>
</configuration>
</plugin>
