Maven的JAXB2-插件：错误解析架构位置，即使XSD和XJB文件都在同一个位置

Question

我有一个pom.xml看起来象下面这样： -

<?xml version="1.0" encoding="UTF-8"?>

       </execution> 
       </executions> 
      </plugin> 

     </plugins> 
    </build> 

</project> 

我n5k.xjb文件看起来像下面： -

<?xml version="1.0" ?> 
<jaxb:bindings version="1.0" xmlns:jaxb="http://java.sun.com/xml/ns/jaxb" schemaLocation="./n5k.xsd"> 
     <jaxb:bindings> 
      <jaxb:globalBindings typesafeEnumMaxMembers="1024"/> 
     </jaxb:bindings> 
</jaxb:bindings> 

我n7k.xjb看起来象下面这样： -

<?xml version="1.0" ?> 
<jaxb:bindings version="1.0" xmlns:jaxb="http://java.sun.com/xml/ns/jaxb" schemaLocation="n7k.xsd"> 
     <jaxb:bindings> 
      <jaxb:globalBindings typesafeEnumMaxMembers="1024"/> 
     </jaxb:bindings> 
</jaxb:bindings> 

但在编制我收到以下错误： -

Error while parsing schema(s).Location [ file:/Users/tuk/code/github/eros/main/schema/src/main/xsd/com/eros/model/nato/custom_xsds/n5k.xjb{2,102}]. 
com.sun.istack.SAXParseException2; systemId: file:/Users/tuk/code/github/eros/main/schema/src/main/xsd/com/eros/model/nato/custom_xsds/n5k.xjb; lineNumber: 2; columnNumber: 102; "file:/Users/tuk/code/github/eros/main/schema/src/main/xsd/com/eros/model/nato/custom_xsds/n5k.xsd" is not a part of this compilation. Is this a mistake for "file:/Users/tuk/code/github/eros/main/schema/src/main/xsd/com/eros/model/nato/custom_xsds/n7k.xsd" 

有人可以让我知道我在做什么错吗？

环境： -

• 的Java 8
• Maven的3.5

Answer 1

我认为问题来自于n7k.xsd编译。在第二次执行中，您没有配置bindingIncludes。所以显然使用n7k.xjb以及n5k.xjb。并且n5k.xjb参考n5k.xsd这不是此汇编的一部分。

要解决，试着加入：

<bindingIncludes> 
    <include>n7k.xjb</include> 
</bindingIncludes> 

到第二执行的配置。
