Question

我无法在我的网络应用中使用yui-compressor maven插件。当我运行maven时，我得到以下错误

[INFO] Internal error in the plugin manager executing goal 'net.sf.alchim:yuicompressor-maven-plugin:0.7.1:compress': Unable to load the mojo 'net.sf.alchim:
yuicompressor-maven-plugin:0.7.1:compress' 
in the plugin 'net.sf.alchim:yuicompressor-maven-plugin'. A required class is missing: org.mozilla.javascript.ErrorReporter

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

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版本似乎不是on the official repository。也许是一个依赖解决问题？

Answer 2

请参阅主题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

我也错过了ErrorReporter类。我通过构建一个带有依赖关系的jar来解决它，然后我转而在我的Web应用程序中使用

<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，一切都奏效了。在我的jar中我可以看到org.mozilla.javascript.ErrorReporter.class在那里，然后Maven会为我编译。
