我正在使用YUI Compressor压缩我的网络应用程序中的JS文件。

我已根据the plugin's site上的说明配置了该插件。

这是POM插件conf：

这是压缩时的日志：

These will use the artifact files already in the core ClassRealm instead, to allow them to be included in PluginDescriptor.getArtifacts().

问题是，虽然文件聚合成一个文件，但它没有压缩。

上面的链接使用版本1.1，我使用的插件版本是0.7.1。这会有什么不同吗？

有人能告诉我这里有什么问题吗？

PS：我在日志中混淆了一些文字以遵守我公司的合规规则，因此您可能会在某些地方发现不匹配。

根据我的阅读，您不配置应检查或压缩js文件的位置（因为您不使用默认配置）。您只需配置聚合。

为了更快速地使用了issue tracker of yuicompressor-maven-plugin

解决方案（从project FAQ复制/粘贴）

因为：

  • 您设置<nosuffix>true</nosuffix>

  • 你的脚本在src / main / webapp和maven-war-plugin下将src / main / webapp中的每个文件复制到目标（无论时间戳，......）并进行战争（在同一执行中）

解决方法：

  • 将您的脚本目录从webapp

    移出 
    <plugin>
  <groupId>@project.groupId@</groupId>
  <artifactId>yuicompressor-maven-plugin</artifactId>
  ...
  <configuration>
    <!-- default ${project.build.sourceDirectory}/../js == src/main/js -->
    <sourceDirectory>src/main/javascript</sourceDirectory>

  • 或者从要复制的文件列表中排除“脚本”

    <!-- adapted from https://github.com/davidB/yuicompressor-maven-plugin/blob/master/src/it/demo01/pom.xml -->
<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-war-plugin</artifactId>
  <configuration>
    <warSourceExcludes>scripts/**</warSourceExcludes>
  </configuration>
</plugin>

我知道这篇文章很老，但我遇到了同样的事情，这就是我发现的。希望这也有助于其他人。

这很棘手。这与nosuffix配置选项有关。如果删除nosuffix选项，则缩小按预期工作。

如果你真的必须有nosuffix，那么你需要将执行阶段改为“package”。

    <executions>
      <execution>
        <phase>package</phase>
          <goals>
    ......
    .....

在准备资源之前的任何阶段都不起作用，因为在构建战争时，它从原始源位置获取js，从而覆盖目标目录中的缩小的js（在准备资源阶段创建）。

当你删除nosuffix时缩小是有效的，因为在打包阶段，文件名不同，所以没有文件的覆盖，你会在目标目录中看到缩小和非缩小的js文件。

至少这是我的理解。

您可以尝试为jslint定义单独的执行并压缩，看看是否有效吗？

<executions>
    <execution>
        <goals>
            <goal>jslint</goal>         
        </goals>
        <configuration> ... </configuration>
    </execution>
    <execution>
        <goals>
            <goal>compress</goal>         
        </goals>
        <configuration> ... </configuration>
    </execution>
</executions>

答案 3 :(得分：0)

YUI压缩器（作为此maven插件中的依赖项包含）使用“修补”版本的Mozilla Rhino：

  • 解释javascript
  • 压缩局部变量名称（“补丁”）

通过将自己的依赖添加到Rhino（in your previous question），我认为这些“补丁”被覆盖，将这个maven插件变成无用的东西：名称压缩，空格删除行为消失了。

所以从你的pom中移除rhino，然后回去解决你的第一个问题！
