Maven jaxb2：xjc无法生成代码

I have added the following plugin into the Maven build in pom.xml

我已将以下插件添加到pom.xml中的Maven构建中

<plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>jaxb2-maven-plugin</artifactId>
    <executions>
        <execution>
            <phase>generate-sources</phase>
            <goals>
                <goal>xjc</goal>
            </goals>
            <configuration> 
                <extension>true</extension>                             
                <clearOutputDir>false</clearOutputDir>
                <schemaDirectory>${basedir}/src/main/resources/xsd</schemaDirectory>
                <schemaFiles>myapp.xsd</schemaFiles>                                                        
                <outputDirectory>${basedir}/src/main/java</outputDirectory>         
                <bindingDirectory>src/main/resources/xsd</bindingDirectory>     
                <bindingFiles>myapp-bindings.xjb</bindingFiles>
            </configuration>
        </execution>
    </executions>                       

</plugin>

Following is the build error.

以下是构建错误。

I am confused, why is the plugin not referring to the paths and files specified in the configuration.

我很困惑,为什么插件没有引用配置中指定的路径和文件。

7 个解决方案

#1

Version 2.1 has changed how sources are specified

版本2.1已更改了指定源的方式

http://mojo.codehaus.org/jaxb2-maven-plugin/xjc-mojo.html#sources

e.g

<configuration>
...
  <sources>
     <source>some/explicit/relative/file.xsd</source>
     <source>/another/absolute/path/to/a/specification.xsd</source>
     <source>a/directory/holding/xsds</source>
 </sources>
</configuration>

I'm having a whole world of other problems so sticking with 1.6 as jshark suggested is a good plan

我有一整个其他问题的世界所以坚持使用1.6,因为jshark建议这是一个很好的计划

#2

version 2.1 has a bug.

版本2.1有一个错误。

You can use <version>2.2</version> with the new syntax:

您可以使用 2.2 和新语法:

<configuration>
...
  <sources>
     <source>some/explicit/relative/file.xsd</source>
     <source>/another/absolute/path/to/a/specification.xsd</source>
     <source>a/directory/holding/xsds</source>
 </sources>
</configuration>

You can use <version>1.6</version> with the old syntax:

您可以使用旧版语法使用 1.6 :

<configuration>
    ...
    <schemaDirectory>${basedir}/src/main/resources/xsd</schemaDirectory>
    <schemaFiles>myapp.xsd</schemaFiles> 
</configuration>

#3

I had the same problem today, and resolved it by putting:

我今天遇到了同样的问题,并通过以下方式解决了这个问题

<version>1.6</version>

on the plugin definition (which is in general good practice to do)

关于插件定义(这是一般的好习惯)

We can also use as below:

我们也可以使用如下:

           <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>

I got it working by setting compiler version to JDK 1.8 and jaxb2-maven-plugin version 1.5 According to the documention it will work with minimum JDK 1.6 [ The link may drop dead if its changed in the site]. For example :

我通过将编译器版本设置为JDK 1.8和jaxb2-maven-plugin 1.5版来实现它。根据文档,它将以最小JDK 1.6工作[如果链接在站点中发生更改,则链接可能会丢失]。例如 :

I resolved it by checking "Force Update of Snapshot/Release" option in eclipse maven update.

我通过在eclipse maven update中选中“Force Update of Snapshot / Release”选项来解决它。

It forces it to update all of the related dependencies.

它强制它更新所有相关的依赖项。

It will be works, if you just add xerces dependency to end of your jaxb plugin declaration. It's so simple: the plugin just need some class to execution. Give it him now :) I. Senatov.

如果您只是将xerces依赖项添加到jaxb插件声明的结尾,它将会起作用。它很简单:插件只需要一些类来执行。现在就给他:)我。塞纳托夫。
