如何使用Gradle从WSDL和XSD生成类，与maven-jaxb2-plugin相当。

Question

我想要将我的Maven2构建文件转换为gradle。 使用gradle从WSDL + XSD生成java类似乎没有进一步的文档，也没有适用于此的gradle插件。 我使用了以下配置与maven，并搜索了gradle的等效配置。

<!-- plugin for generating the classes from the WSDL+XSD -->
<plugin>
  <groupId>org.jvnet.jaxb2.maven2</groupId>
  <artifactId>maven-jaxb2-plugin</artifactId>
  <version>0.7.3</version>
  <executions>
    <execution>
      <id>app1-stub-generation</id>
      <goals>
        <goal>generate</goal>
      </goals>
      <configuration>
        <schemaDirectory>${project.build.directory}/wsdl/app1</schemaDirectory>
        <schemaIncludes>
          <include>*.xsd</include>
        </schemaIncludes>
        <generatePackage>org.app1.ws.generated</generatePackage>
        <generateDirectory>${project.build.directory}/generated-sources/app1</generateDirectory>
        <strict>true</strict>
      </configuration>
    </execution>
    <execution>
      <id>app2-v1-stub-generation</id>
      <goals>
        <goal>generate</goal>
      </goals>
      <configuration>
        <schemaDirectory>src/main/resources/wsdl</schemaDirectory>
        <schemaIncludes>
          <include>v1/*.xsd</include>
        </schemaIncludes>
        <generatePackage>org.app2.ws.generated.v1</generatePackage>
        <generateDirectory>${project.build.directory}/generated-sources/v1</generateDirectory>
        <strict>true</strict>
      </configuration>
    </execution>
    <execution>
      <id>app2-v2-stub-generation</id>
      <goals>
        <goal>generate</goal>
      </goals>
      <configuration>
        <schemaDirectory>src/main/resources/wsdl</schemaDirectory>
        <schemaIncludes>
          <include>v2/*.xsd</include>
        </schemaIncludes>
        <generatePackage>org.app2.ws.generated.v2</generatePackage>
        <generateDirectory>${project.build.directory}/generated-sources/v2</generateDirectory>
        <strict>true</strict>
      </configuration>
    </execution>
  </executions>
</plugin>

我解决了它...

configurations {
    jaxb
}

dependencies {
    jaxb group: 'com.sun.xml.bind', name: 'jaxb-xjc', version: '2.2.4-1'
}

task jaxb () {
    // output directory
    jaxbTargetDir = file( "${buildDir}/generated-sources" )
    jaxbTargetDirV19 = file( jaxbTargetDir.path + '/v19' )
    jaxbTargetDirV110 = file( jaxbTargetDir.path + '/v110' )
    jaxbTargetDirOtherWs = file( jaxbTargetDir.path + '/otherWs' )

    // perform actions
    doLast {
        jaxbTargetDirV19.mkdirs()
        jaxbTargetDirV110.mkdirs()
        jaxbTargetDirOtherWs.mkdirs()

        ant.taskdef(name: 'xjc', classname: 'com.sun.tools.xjc.XJCTask', classpath: configurations.jaxb.asPath)
        ant.jaxbTargetDirV19 = jaxbTargetDirV19
        ant.jaxbTargetDirV110 = jaxbTargetDirV110
        ant.jaxbTargetDirOtherWs = jaxbTargetDirOtherWs

        // My-Webservice v1.10
        ant.xjc(
                destdir: '${jaxbTargetDirV110}',
                package: 'mypackage.ws.generated.v110',
                schema: 'src/main/resources/wsdl/v1.10/MyServiceSchema.xsd'
        )

        // My-Webservice v1.9
        ant.xjc(
                destdir: '${jaxbTargetDirV19}',
                package: 'mypackage.ws.generated.v19',
                schema: 'src/main/resources/wsdl/v1.9/MyServiceSchema.xsd'
        )

        // OtherWs-Webservice
        ant.xjc(
                destdir: '${jaxbTargetDirOtherWs}',
                package: 'mypackage.otherws.generated',
                schema: 'src/main/resources/wsdl/OtherWsServiceSchema.xsd'
        )
    }
}
compileJava.dependsOn jaxb

如果还有人在追踪这个问题，有人尝试给它添加JAXB扩展了吗？当我这样做时，我会收到一个类似于“提供程序xx不是子类型”的错误，其中“xx”是扩展的主要插件类。 - David M. Karr

Answer 2

如果您找不到一个特定需求的Gradle插件（并且不想编写自己的插件），可以寻找Ant任务。这里有一个适用于JAXB的Ant任务：XJC Ant Task。 任何Ant任务都可以直接从Gradle中使用（请参阅Using Ant from Gradle）。在未来，Gradle还将支持执行Maven插件。

Answer 3

按照此处描述使用插件：https://github.com/nilsmagnus/wsdl2java

注意：截至2020年，此建议已不再适用，因为推荐的插件已停用，并且无法与更新版本的Gradle一起使用。
