Question

我是maven的新手，这是我第一次使用maven-jaxb2-plugin从.xsd架构生成java类。

这是我的pom.xml：

 <properties>
    <java.source.version>1.6</java.source.version>
    <java.target.version>1.6</java.target.version>
 </properties>
 <build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <configuration>
                <source>${java.source.version}</source>
                <target>${java.target.version}</target>
            </configuration>

        </plugin>


        <plugin>
            <groupId>org.jvnet.jaxb2.maven2</groupId>
            <artifactId>maven-jaxb2-plugin</artifactId>
            <version>0.8.3</version>
            <executions>
                <execution>
                    <goals>
                        <goal>generate</goal>
                    </goals>
                </execution>
            </executions>

            <configuration>
                <schemaDirectory>src/main/resources/schema</schemaDirectory>
                <schemaIncludes>
                    <include>mySchema.xsd</include>
                </schemaIncludes>
                <generatePackage>it.mycompany.jaxb2</generatePackage>
                <readOnly>true</readOnly>
            </configuration>
        </plugin>
    </plugins>
    </build>    
<dependencies>
    <!-- A few dependiences -->
</dependencies>

麻烦的是，当我尝试运行时

mvn install

我收到以下错误

以这种方式配置Maven：

mvn --version Maven home：C：\ Program Files （x86）\ apache-maven-3.1.1 \ bin .. Java版本：1.6.0_45，供应商：Sun. Microsystems Inc. Java home：C：\ Program Files （x86）\ Java \ jdk1.6.0_45 \ jre默认语言环境：it_IT，平台编码： Cp1252操作系统名称：“windows 8”，版本：“6.2”，arch：“x86”，系列： “窗口”

我在哪里做错了？

Answer 1

问题是maven-jaxb2-plugin默认使用的是jaxb-xjc的2.2.6版本，这个版本有一些问题

默认语言环境：it_IT

但仅适用于美国区域设置。然后我添加了以下对我的pom的依赖

  <dependency>
    <groupId>com.sun.xml.bind</groupId>
    <artifactId>jaxb-xjc</artifactId>
    <version>2.2.5</version>
  </dependency>

现在一切正常。

使用maven-jaxb2-plugin的非法模式字符
