Question

我已将以下插件添加到pom.xml中的Maven构建

<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>

以下是构建错误。

我很困惑，为什么插件没有引用配置中指定的路径和文件。

Answer 1

版本2.1已更改指定源的方式

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>

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

Answer 2

版本2.1有一个错误。

您可以使用<version>2.2</version>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>

您可以将<version>1.6</version>与旧语法结合使用：

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

Answer 3

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>

关于插件定义（这是一般的好习惯）

Answer 4

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>

Answer 5

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 :

<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">

  <groupId>com.mntq.jaxb.xsd.to.pojo</groupId>
  <artifactId>XsdToPojo</artifactId>
  <version>0.0.1-SNAPSHOT</version>


  <build>
        <finalName>PersistencePoJO</finalName>
        <plugins>
            <plugin>

                    <target>1.8</target>
                </configuration>
            </plugin>

                    </goals>
                </execution>
            </executions>

                <packageName>com.mntq.jaxb.pojo</packageName>
            </configuration>
        </plugin>
        </plugins>
    </build>
</project>

Answer 6

我通过检查＆＃34;强制更新快照/发布＆＃34;来解决它。 eclipse maven update中的选项。

它强制它更新所有相关的依赖项。

Answer 7

如果您只是将xerces依赖项添加到jaxb插件声明的末尾，那将是可行的。很简单：插件只需要一些类即可执行。现在给他：) I.塞纳托夫。

Answer 8

就我而言，我可以通过将jdk编译器版本从jdk 10降级到jdk 1.8来工作

Answer 9

在某些情况下，例如，在构建之前，您应该使用mvn clean

mvn clean compile

Maven jaxb2：xjc无法生成代码
