JAXB2 plugin

This started as a fork from ewerk/gradle-plugins/jaxb2.

Description

This plugin makes it easy to generate Java source code from XML schema files (.xsd). Internally the plugin relies on the JAXB2 ant task for generating the code. The examples below show how the plugin can be used.

At the moment the plugin is simplistic and just supports creating Java code from XSD. JAXB2 specific special stuff like binding files or additional task parameters are currently not supported but can surely make it into the plugin in future.

Dependency management

The plugin creates a own 'jaxb2' configuration and adds it to the project. Then it adds all needed dependencies to execute the JAXB ant task. You may need to extend are change these dependencies. As we have the jaxb2 configuration, you can do this by using the default dependencies {} closure of your project. This is shown in the examples below.

Configuration

taskName

The full qualified name of the JAXB2 ant task the does the real work. Defaults to org.jvnet.jaxb2_commons.xjc.XJC2Task. Normally there will be need to change this.

xjc

This is the container for configuring the distinct generation steps. It can be repeated as needed within the jaxb2 extension. The container structure is as follows:

xjc {
  'generation-step-name' {
    // optional, defaults to src/generated/java
    generatedSourcesDir = 'any/relative/path'
    
    // full qualified base package for the classes to be generated
    basePackage = 'com.any.app'
    
    // relative path the XSD file to generate the code from
    schema = 'src/main/xsd/any-file.xsd'
    
    // relative path to directory including binding files
    // all files of pattern **/*.xjb will be included
    // default to null (no binding files used)
    // Optional, can be left away
    bindingsDir = 'src/main/xsb'
    
    // comma separated list of binding file includes
    // falls back to '**/*.xjb' if not specified
    includedBindingFiles = 'any.xjb, subdir/test.xjb'
    
    additionalArgs = '-nv -dtd'

    // output encoding of the generated files
    encoding = 'UTF-8'
  }
}

Examples

Use via Gradle plugin portal

Plugin page, Groovy & Kotlin DSL: https://plugins.gradle.org/plugin/com.github.gradlecommunity.jaxb2

plugins {
  id 'com.github.gradlecommunity.jaxb2' version '3.1.0'
}

Full configuration example

plugins {
  id 'com.github.gradlecommunity.jaxb2' version '3.1.0'
}

repositories {
  mavenCentral()
}

// the whole dependency container could be left out
dependencies {
  // default JAXB2 libs added by the plugin
  jaxb2 'org.jvnet.jaxb2_commons:jaxb2-basics-runtime:0.9.5'
  jaxb2 'org.jvnet.jaxb2_commons:jaxb2-basics-ant:0.9.5'
  jaxb2 'org.jvnet.jaxb2_commons:jaxb2-basics:0.9.5'

  // default JAXB libs added by the plugin
  jaxb2 'com.sun.xml.bind:jaxb-core:2.2.11'
  jaxb2 'com.sun.xml.bind:jaxb-xjc:2.2.11'
  jaxb2 'com.sun.xml.bind:jaxb-impl:2.2.11'
  
  // any custom libraries here
  jaxb2 'com. …'
}

jaxb2 {
  xjc {
    'request-classes' {
      basePackage = 'com.any.app.model.request'
      schema = 'src/main/xsd/request.xsd'
      encoding = 'UTF-8'
      extension = true 
    }
  }

  xjc {
    'response-classes' {
      basePackage = 'com.any.app.model.response'
      schema = 'src/main/xsd/response.xsd'
      bindings = 'src/main/xsb'
    }
  }
}

Minimal configuration example

plugins {
  id 'com.github.gradlecommunity.jaxb2' version '3.1.0'
}

repositories {
  mavenCentral()
}

jaxb2 {
  xjc {
    'request-classes' {
      basePackage = 'com.any.app.model.request'
      schema = 'src/main/xsd/request.xsd'
    }
  }
