无法从 XSD 生成类

Question

这是我用来生成类的 pom.xml。我尝试通过 Maven 构建通过提供目标作为包来生成。我也尝试使用 mvn clean install ，我在控制台中没有看到任何错误，但是，“target/ generated-sources/jaxb”中没有生成任何类

这是我一直在尝试生成 java 类的示例 XSD 文件，如果需要对 xsd 文件进行任何更改，请告诉我。

<xs:element name="UserInfo">
    <xs:complexType>
        <xs:sequence>
            <xs:element name="firsName" type="xs:string" />
            <xs:element name="middleName" type="xs:string" />
            <xs:element name="lastName" type="xs:string" />
            <xs:element name="dob" type="xs:string" />
            <xs:element name="ssn" type="xs:string" />
            <xs:element name="emailId" type="xs:string" />
            <xs:element name="userId" type="xs:string" />

这是创建的初始基本目录结构。

\n\n

\xe2\x94\x94\xe2\x94\x80\xe2\x94\x80\xe2\x94\x80src\n    \xe2\x94\x9c\xe2\x94\x80\xe2\x94\x80\xe2\x94\x80main\n    \xe2\x94\x82   \xe2\x94\x94\xe2\x94\x80\xe2\x94\x80\xe2\x94\x80resources\n    \xe2\x94\x94\xe2\x94\x80\xe2\x94\x80\xe2\x94\x80test\n

proto.xsd被放置在资源下。

\n\n

xs上面的模式中有前缀，没有命名空间的声明。因此将其更改如下：
\n proto.xsd

\n\n

<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">\n<xs:element name="UserInfo" >\n    <xs:complexType>\n        <xs:sequence>\n            <xs:element name="firsName" type="xs:string" />\n            <xs:element name="middleName" type="xs:string" />\n            <xs:element name="lastName" type="xs:string" />\n            <xs:element name="dob" type="xs:string" />\n            <xs:element name="ssn" type="xs:string" />\n            <xs:element name="emailId" type="xs:string" />\n            <xs:element name="userId" type="xs:string" />\n            <xs:element name="password1" type="xs:string" />\n            <xs:element name="password2" type="xs:string" />\n            <xs:element name="Address">\n                <xs:complexType>\n                    <xs:sequence>\n                        <xs:element name="addressline1" type="xs:string" />\n                        <xs:element name="addressline2" type="xs:string" />\n                        <xs:element name="zipCode" type="xs:int" />\n                        <xs:element name="street" type="xs:string" />\n                        <xs:element name="apt" type="xs:string" />\n                        <xs:element name="city" type="xs:string" />\n                        <xs:element name="state" type="xs:string" />\n                        <xs:element name="country" type="xs:string" />\n                    </xs:sequence>\n                </xs:complexType>\n            </xs:element>\n        </xs:sequence>\n    </xs:complexType>\n</xs:element>\n</xs:schema>\n

\n\n

这是pom.xml文件：

\n\n

<project xmlns="http://maven.apache.org/POM/4.0.0"   \nxmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  \n  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0   \nhttp://maven.apache.org/xsd/maven-4.0.0.xsd">  \n\n  <modelVersion>4.0.0</modelVersion>  \n  <groupId>com.login.app</groupId>\n  <artifactId>Login</artifactId>\n  <version>0.0.1-SNAPSHOT</version>\n  <packaging>jar</packaging>\n\n  <name>Login</name>\n  <url>http://maven.apache.org</url>\n\n  <properties>\n      <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>\n  </properties>\n\n  <dependencies>\n      <dependency>\n          <groupId>junit</groupId>\n          <artifactId>junit</artifactId>\n          <version>3.8.1</version>\n          <scope>test</scope>\n      </dependency>\n  </dependencies>\n\n  <build>\n      <pluginManagement>\n          <plugins>\n              <plugin>\n                  <groupId>org.apache.maven.plugins</groupId>\n                  <artifactId>maven-compiler-plugin</artifactId>\n\n                  <configuration>\n                      <source>1.8</source>\n                      <target>1.8</target>\n                  </configuration>\n              </plugin>\n          </plugins>\n      </pluginManagement>\n      <plugins>\n          <plugin>\n              <groupId>org.codehaus.mojo</groupId>\n              <artifactId>jaxb2-maven-plugin</artifactId>\n              <version>1.5</version>\n              <executions>\n                  <execution>\n                      <id>xjc</id>\n                      <goals>\n                          <goal>xjc</goal>\n                      </goals>\n                  </execution>\n              </executions>\n              <configuration>\n                  <outputDirectory>target/generated-sources/jaxb</outputDirectory>\n                  <packageName>com.login.app</packageName>\n                  <schemaDirectory>src/main/resources</schemaDirectory>\n                  <schemaFiles>proto.xsd</schemaFiles>\n                </configuration>\n          </plugin>\n\n      </plugins>\n</build>\n\n</project>\n

\n\n

如果您注意到上面的内容，schemaDirectory当 xsd 文件放置在那里时，值会相应地更改。

\n\n

现在，运行以下 Maven 命令：

\n\n

mvn clean install\n

\n\n

输出：
