java - maven-jaxb2-plugin:即使 xsd 和 xjb 文件位于同一位置，解析架构位置也会出错

Question

我有一个 pom.xml ，如下所示:-

我的 n5k.xjb 文件如下所示:-

<?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>

我的 n7k.xjb 如下所示:-

<?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>

但是在编译时我收到以下错误:-

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做错了什么吗？

环境:-

• Java 8
• Maven 3.5

Answer 1

我认为问题出在n7k.xsd的编译上。在第二次执行中，您没有配置 bindingIncludes。显然，n7k.xjb 和 n5k.xjb 都被使用。 n5k.xjb 引用了 n5k.xsd，它不属于此编译的一部分。

要解决此问题，请尝试添加:

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

到第二次执行的配置。
