1、maven error: Duplicate fragment name

2、解决办法：

    pom.xml的jetty配置中配置

<allowDuplicateFragmentNames>true</allowDuplicateFragmentNames>。

例如：

 

   <plugin>

    <groupId>org.mortbay.jetty</groupId>     <artifactId>jetty-maven-plugin</artifactId>     <version>${jetty.version}</version>     <configuration>      <connectors>       <connector implementation="org.eclipse.jetty.server.nio.SelectChannelConnector">        <port>${webserver.port}</port>       </connector>      </connectors>      <webApp>       <defaultsDescriptor>src/main/resources/webdefault.xml</defaultsDescriptor>            <allowDuplicateFragmentNames>true</allowDuplicateFragmentNames>      </webApp>      <webAppConfig>

      <contextPath>/</contextPath>

     </webAppConfig>      <systemProperties>       <systemProperty>        <name>org.mortbay.util.URI.charset</name>        <value>${project.build.sourceEncoding}</value>       </systemProperty>      </systemProperties>     </configuration>    </plugin>
