我一直在遵循this教程中的确切步骤 . 但是，无论我尝试什么，我都会得到同样的错误 .

我有两个应该在xsd文件中生成的元素：GetStudentDetailsRequest和GetStudentDetailsResponse . 这是我的.xsd文件：

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
           targetNamespace="http://in28minutes.com/students"
           xmlns:tns="http://in28minutes.com/students" elementFormDefault="qualified">

    <xs:element name="GetStudentDetailsRequest">
        <xs:complexType>
            <xs:sequence>
                <xs:element name= "id" type="xs:int"/>
            </xs:sequence>
        </xs:complexType>
    </xs:element>

    <xs:element name="GetStudentDetailsResponse">
        <xs:complexType>
            <xs:sequence>
                <xs:element name= "StudentDetails" type="tns:StudentDetails"/>
            </xs:sequence>
        </xs:complexType>
    </xs:element>

    <xs:complexType name="StudentDetails">
        <xs:sequence>
            <xs:element name="id" type="xs:int"/>
            <xs:element name="name" type="xs:string"/>
            <xs:element name="passportNumber" type="xs:string"/>
        </xs:sequence>
    </xs:complexType>

</xs:schema>

还有我的pom.xml：

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

如果我运行mvn clean install我会收到以下错误：

我已经看到一些建议从java 9切换到java 8，尝试不同的jdk，但似乎没有任何工作 .

    使用正确的artifactId更新javax.activation依赖项 . 它是javax.activation而不仅仅是激活

    <dependency>
        <groupId>javax.activation</groupId>                                                                                                                                                                                                                               
        <artifactId>javax.activation</artifactId>
        <version>1.1</version>
</dependency>

    否则，使用jdk 1.8将解决问题，因为它将使用jdk的javax.activation版本 .

    用你当前的pom测试jdk1.8并且它有效导出JAVA_HOME = / Library / Java / JavaVirtualMachines / jdk1.8.0_05.jdk / Contents / Home /

    但是，使用jdk 1.9，您需要更新上面的pom以使其正常工作 .
