yui 压缩器 maven：缺少必需的类：org.mozilla.javascript.ErrorReporter

Question

我无法在我的网络应用程序中使用 yui-compressor maven 插件。当我运行 maven 时出现以下错误

[信息] 插件管理器执行目标 'net.sf.alchim:yuicompressor-maven-plugin:0.7.1:compress' 出现内部错误：无法加载 mojo 'net.sf.alchim: yuicompressor-maven-plugin:0.7.1:compress' 在插件“net.sf.alchim:yuicompressor-maven-plugin”中。缺少必需的类：org.mozilla.javascript.ErrorReporter

后来我发现rhino js插件包含org.mozilla.javascript.ErrorReporter这个类。所以我在依赖标签中包含了这个插件，但我仍然得到同样的错误。

有没有人遇到过这样的错误。

Answer 1

你能试试最新版本（1.1）吗？

0.7.1 版本似乎甚至不是on the official repository。可能是依赖解析问题？

Answer 2

见话题Yui compressor StringIndexOutOfBoundsException on jboss

在 web 应用程序上使用 yuicompressor 的唯一方法是手动将其与 rhino 依赖项合并。否则，要运行的应用程序将需要在类加载器加载序列中指定所需的 jar 序列（youcompressor 必须在 rhino 之前）。

Answer 3

我也为缺少 ErrorReporter 类而苦苦挣扎。我通过构建一个 jar-with-dependencies 解决了这个问题，然后我转身在我的网络应用程序中使用它，

<plugin>
<artifactId>maven-assembly-plugin</artifactId>
<executions>
  <execution>
    <phase>package</phase>
    <goals>
      <goal>attached</goal>
    </goals>
  </execution>
</executions>
<configuration>
  <descriptorRefs>
    <descriptorRef>jar-with-dependencies</descriptorRef>
  </descriptorRefs>
</configuration>

一旦我这样做了，一切正常。在我的 jar 中，我可以看到 org.mozilla.javascript.ErrorReporter.class 在那里，然后 Maven 将为我编译。
