帶有Maven-jaxb2-plugin的非法模式字符

Question

我是maven的新手，這是我第一次使用maven-jaxb2-plugin從.xsd模式生成Java類。

這是我的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>

問題是當我嘗試跑步時

mvn安裝

我收到以下錯誤

Maven的配置方式如下：

mvn --version Maven主目錄：C：\\ Program Files（x86）\\ apache-maven-3.1.1 \\ bin .. Java版本：1.6.0_45，供應商：Sun Microsystems Inc. Java主目錄：C：\\ Program Files（x86 ）\\ Java \\ jdk1.6.0_45 \\ jre默認語言環境：it_IT，平台編碼：Cp1252操作系統名稱：“ windows 8”，版本：“ 6.2”，arch：“ x86”，家族：“ windows”

我在哪里做錯了？

Answer 1

問題是默認的maven-jaxb2-plugin使用jaxb-xjc的2.2.6版本，該版本存在一些問題

默認語言環境：it_IT

但僅適用於美國語言環境。 然后我對pom添加了以下依賴性

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

現在一切正常。
