着色Java jar - Xerces问题

Question

我正在运行Hadoop Mapreduce作业。我使用的xerces和Hadoop发行版看起来不同。我想遮蔽我的xerces。我该怎么做？

这样做：

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-shade-plugin</artifactId>
    <version>2.4.1</version>
    <executions>
        <execution>
            <phase>package</phase>
            <goals>
                <goal>shade</goal>
            </goals>
            <configuration>
                 <artifactSet>
                     <excludes>
                         <exclude>xerces:xercesImpl:jar:</exclude>
                     </excludes>
                 </artifactSet>
                 <relocations>
                     <relocation>
                         <pattern>org.apache.xerces.impl.*</pattern>
                             <shadedPattern>org.shaded.xerces.impl.*</shadedPattern>
                     </relocation>
                 </relocations>
             </configuration>
         </execution>
     </executions>
 </plugin>

发出此错误。谷歌搜索没有多大帮助：

[INFO] ------------------------------------------------------------------------
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-shade-plugin:2.4.1:shade (default) on project dsl-mapreduce: Error creating shaded jar: Error in ASM processing class com/ibm/icu/impl/data/LocaleElements_zh__PINYIN.class: 48188 -> [Help 1]

我没有在任何地方使用com/ibm/icu/impl，icu或icu4j也不存在mvn dependency:tree。

编辑：jar在Java 8上编译，Hadoop在Java 7上编译。
