Maven的JAXB2-插件：錯誤解析架構位置，即使XSD和XJB文件都在同一個位置

Question

我有一個pom.xml看起來象下面這樣： -

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

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

     </plugins> 
    </build> 

</project> 

我n5k.xjb文件看起來像下面： -

<?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看起來象下面這樣： -

<?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> 

但在編制我收到以下錯誤： -

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" 

有人可以讓我知道我在做什麼錯嗎？

環境： -

• 的Java 8
• Maven的3.5

Answer 1

我認爲問題來自於n7k.xsd編譯。在第二次執行中，您沒有配置bindingIncludes。所以顯然使用n7k.xjb以及n5k.xjb。並且n5k.xjb參考n5k.xsd這不是此彙編的一部分。

要解決，試着加入：

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

到第二執行的配置。
