Maven Jaxb2 xjc插件錯誤沒有模式被發現

這些天我花了一段時間在JAXB上將XSD轉換爲Java類，反之亦然。這是一個非常好的初學者教程，http://www.journaldev.com/1312/how-to-generate-java-classes-from-xsd-using-xjc-maven-plugin。我嚴格按照步驟操作，但當mvn clean installMaven Jaxb2 xjc插件錯誤沒有模式被發現

這裏是我的pom.xml文件時總是出錯。

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

     </dependency> 
    </dependencies> 


    <properties> 
     <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> 
    </properties> 


    <build> 
     <plugins> 
      <!-- Plugin required to build java classes from XSD using XJC --> 
      <plugin> 
       <groupId>org.codehaus.mojo</groupId> 
       <artifactId>jaxb2-maven-plugin</artifactId> 
       <version>1.5</version> 
       <executions> 
        <execution> 
         <id>xjc</id> 
         <goals> 
          <goal>xjc</goal> 
         </goals> 
        </execution> 
       </executions> 
       <configuration> 
        <!-- The name of your generated source package --> 
        <arguments>-extension -npa -b ${project.basedir}/src/main/java/com/moodys/jaxb/global.xjb</arguments> 
       </configuration> 
      </plugin> 

     </plugins> 
    </build> 

</project>

但是當我鍵入mvn clean install，它總是給我的錯誤如下：

C:\Users\congy\Desktop\Work\workspace\JaxbFromClass>mvn clean jaxb2:xjc

誰能告訴我原因，或簡單地告訴我，我應該指的進一步的信息？

另一個問題是：根據這個問題Difference of Maven JAXB plugins，至少有三個jaxb插件。所有這些插件都是爲了同樣的目的而生成的？如果是這樣，爲什麼？

在此先感謝！

由於您沒有提供任何schemaDirectory，插件正嘗試從the default schema directory中的所有XML模式文件生成Java源文件。你應該根據documentation配置插件：

<plugin> 
    <groupId>org.codehaus.mojo</groupId> 
    <artifactId>jaxb2-maven-plugin</artifactId> 
    <version>1.5</version> 
    <executions> 
    <execution> 
     <id>id1</id> 
     <goals> 
    <goal>xjc</goal> 
     </goals> 
     <configuration> 
     <outputDirectory>target/generated-sources/jaxb</outputDirectory> 
     <packageName>com.your.package.jaxb</packageName> 
     <schemaDirectory>src/main/xsd</schemaDirectory> 
     <schemaFiles>jaxb.xsd</schemaFiles> 
     </configuration> 
    </execution> 
    </executions> 
</plugin>

這樣做，作爲下面使用。仍然給出同樣的錯誤。 – jamie

嘗試刪除以下行： target/generated-sources/jaxb – BlueLettuce16

儘量確保jaxb.xsd下的src/main /資源存在，這個插件是華林，因爲它coudn't找到方案在指定的位置。

實際上是什麼jaxb.xsd？它是一個文件名嗎？ – zygimantus

我們可以在pom.xml文件

<plugin> 
     <groupId>org.codehaus.mojo</groupId> 
     <artifactId>jaxb2-maven-plugin</artifactId> 
     <version>1.5</version> 
     <executions> 
      <execution> 
       <id>id1</id> 
       <goals> 
        <goal>xjc</goal> 
       </goals> 
       <configuration> 
        <outputDirectory>src/main/java</outputDirectory> 
        <clearOutputDir>false</clearOutputDir> 
        <packageName>com.subu.xsd.model</packageName> 
        <schemaDirectory>src/main/java/schemadir</schemaDirectory> 
        <schemaFiles>XYZ.xsd</schemaFiles> 
       </configuration> 
      </execution> 
     </executions> 
    </plugin>
