我的Maven项目一切都很好，直到添加webutilities库。
我添加了依赖项和存储库：
<dependency>
<groupId>com.google.javascript</groupId>
<artifactId>closure-compiler</artifactId>
<version>v20140407</version>
<type>jar</type>
</dependency>
..........
<repository>
<id>central</id>
<url>http://repo1.maven.org/maven2/</url>
</repository>
正如在库的页面https://maven-repository.com/artifact/com.googlecode.webutilities/webutilities/0.0.7中所说的那样，并声明了servlet：
<servlet>
<servlet-name>JSCSSMergeServlet</servlet-name>
<servlet-class>com.googlecode.webutilities.servlets.JSCSSMergeServlet</servlet-class>
<!-- This init param is optional and default value is minutes for 7 days in future. -->
<init-param>
<param-name>expiresMinutes</param-name>
<param-value>14400</param-value> <!-- 10 days -->
</init-param>
<!-- This init param is also optional and default value is 'public'.-->
<init-param>
<param-name>cacheControl</param-name>
<param-value>public</param-value>
</init-param>
</servlet>
.......
<servlet-mapping>
<servlet-name>JSCSSMergeServlet</servlet-name>
<url-pattern>*.js</url-pattern>
<url-pattern>*.json</url-pattern>
<url-pattern>*.css</url-pattern>
</servlet-mapping>
如页面所示：https://code.google.com/p/webutilities/wiki/JSCSSMergeServlet
当我尝试使用mvn package -o -X打包时，它会给我一个错误：

在我看来，一些更深层次的依赖导致了这个错误，但我无法弄明白。
