jaxb2(1.x)和selenium不兼容

jaxb2用来将schema转换为java代码，selenium是GUI自动化测试的lib。由于项目中需要同时支持这两个feature，所以一同配置在pom中：

​ 
   
    org.seleniumhq.selenium  
    selenium-java  
    2.48.2 
   

 
   
     
      org.codehaus.mojo  
      jaxb2-maven-plugin  
      1.5
       
         
          inbound-common-v12-xjc  
           
            xjc 
            
           
            target/generated-sources  
            com.xxx.data.v12.common  
            src/main/resources  
            bindings.xml  
            src/main/resources/xsd/ASP1.2  
            Inbound_Common.xsd,Inbound_FailureResponse.xsd, Inbound_OperationalHistory.xsd, Inbound_TotalResponse.xsd  
            true  
            target/.inboundcommonschema1XjcStaleFlag  
            false  
            UTF-8 
           
         
       
     
   

结果执行mvn clean install时报错：

[ERROR]
Failed to execute goal org.codehaus.mojo:jaxb2-maven-plugin:1.5:xjc
(inbound-user-creation-v12-xjc) on project jcat-test-common: DTD factory class
org.apache.xerces.impl.dv.dtd.DTDDVFactoryImpl does not extend from
DTDDVFactory. -> [Help 1]

定位：

从报错看，是在执行jaxb时使用了错误的xerce包，由于项目先加入jaxb2，然后是selenium，所以应该是selenium引入的冲突。为了验证想法，使用mvn dependency:tree查看selenium的依赖库：

[INFO] +- org.seleniumhq.selenium:selenium-java:jar:2.46.0:compile
[INFO] |  +- org.seleniumhq.selenium:selenium-chrome-driver:jar:2.46.0:compile

[INFO] |  |     +- xerces:xercesImpl:jar:2.11.0:compile

解决：

在jaxb2 plugin中添加dependence：

... 
   
     
      xerces  
      xercesImpl  
      2.9.1 
      
     
      xalan  
      xalan  
      2.7.2 
     
   

再次执行mvn clean install，搞定！
