Disclaimer

This project is not developed, supported or in any other way affiliated with Apache, Eclipse or Oracle.

It was a completely independent development by its creator, Alexey Valikov.

It is now maintained by a group of people who are interested in keeping jaxb-tools working with future versions of Java and Jakarta.

JAXB Maven Plugin

This Maven plugin generates Java classes during Maven builds from XML Schemas (as well as WSDL, DTDs, RELAX NG formats).

It wraps and enhances the JAXB Schema Compiler (XJC) with its own set of plugins and customization points.

Quick start

Put your schemas (*.xsd) and bindings (*.xjb) into the src/main/resources folder.
Add the plugin to your pom.xml:

<project ...>
  ...
  <build>
    <plugins>
      <plugin>
        <groupId>org.jvnet.jaxb</groupId>
        <artifactId>jaxb-maven-plugin</artifactId>
        <version>2.0.5</version>
        <executions>
          <execution>
            <goals>
              <goal>generate</goal>
            </goals>
          </execution>
        </executions>
      </plugin>
    </plugins>
  </build>
  ...
</project>

JAXB Versions

The current version 2.X of this plugin supports only JAXB 2.3.

A version of this plugin that supports JAXB >= 3.x is currently being worked on.

If you need an older JAXB version, you can use one of the following variants, which are no longer supported:

org.jvnet.jaxb2.maven2:maven-jaxb22-plugin:0.15.1 - JAXB 2.2.
org.jvnet.jaxb2.maven2:maven-jaxb21-plugin:0.15.2 - JAXB 2.1.
org.jvnet.jaxb2.maven2:maven-jaxb20-plugin:0.15.2 - JAXB 2.0.

Annox

Parse Java annotations from text or XML resources.

Please refer to the wiki for documentation.

// Parse annotation from the string
XAnnotation<XmlRootElement> xannotation =
	(XAnnotation<XmlRootElement>) XAnnotationParser.INSTANCE.parse
		("@jakarta.xml.bind.annotation.XmlRootElement(name=\"foo\")");

// Create an instance of the annotation
XmlRootElement xmlRootElement = xannotation.getResult();
assertEquals("foo", xmlRootElement.name());
assertEquals("##default", xmlRootElement.namespace());

// Analyze the structure of the annotation
assertEquals(String.class, xannotation.getFieldsMap().get("name").getType());
assertEquals("##default", xannotation.getFieldsMap().get("namespace").getResult());

JAXB Annotate Plugin

JAXB Annotate Plugin is capable of adding or removing arbitrary annotations to/from the generated sources.

Please refer to the wiki for documentation.

Usage overview

Annotate your schema using binding files or directly in schema
Add the plugin to the XJC classpath.
Add your annotation classes to the XJC classpath.
Activate the plugin using -Xannotate-switch.

Providing annotations

You can annotate your schema-derived elements using normal Java annotation syntax. (Old XML syntax is still supported but no longer recommended.)

Current limitations:

Annotation classes must be known in compile time. I.e. annotation classes must be made available in the XJC classpath. If you want to use your own annotations, you have to pre-compile them and add your annotation classes to the XJC classpath.
As a consequence, currently you can't use schema-derived enums in your annotations. Since you have to compile annotations before compiling the schema - and as your enums are first generated from the schema, this is a chicken-and-egg-problem.
All class names (classes of annotations or classes you use as values in annotations) must be fully qualified. Inner classes should use the dot (.) as delimiter (not $).

You can put your annotations directly in schema:

<xsd:schema
        xmlns:xsd="http://www.w3.org/2001/XMLSchema"
        xmlns:jaxb="https://jakarta.ee/xml/ns/jaxb"
        jaxb:version="3.0"
        xmlns:annox="http://annox.dev.java.net"
        jaxb:extensionBindingPrefixes="annox">


    <xsd:complexType name="FooType">
        <xsd:annotation>
            <xsd:appinfo>
                <annox:annotate>@java.lang.SuppressWarnings({"unchecked","rawtypes"})</annox:annotate>
                <annox:annotate target="package">@javax.annotation.Generated({"XJC","JAXB Annotate Plugin"})</annox:annotate>
            </xsd:appinfo>
        </xsd:annotation>
        <xsd:sequence>
            <xsd:element name="bar" type="xsd:string"/>
            <xsd:element name="foobar" type="xsd:string">
                <xsd:annotation>
                    <xsd:appinfo>
                        <annox:annotate>@java.lang.SuppressWarnings({"unchecked","rawtypes"})</annox:annotate>
                        <annox:annotate target="setter">@java.lang.Deprecated</annox:annotate>
                        <annox:annotate target="setter-parameter">@java.lang.Deprecated</annox:annotate>
                        <annox:annotate target="getter">@java.lang.Deprecated</annox:annotate>
                        <annox:annotate target="field">@java.lang.Deprecated</annox:annotate>
                        <annox:annotate target="class">@java.lang.Deprecated</annox:annotate>
                    </xsd:appinfo>
                </xsd:annotation>
            </xsd:element>
        </xsd:sequence>
    </xsd:complexType>

    <xs:simpleType name="FooEnum">
        <xs:annotation>
            <xs:appinfo>
                <annox:annotateEnumValueMethod>@java.lang.Deprecated</annox:annotateEnumValueMethod>
            </xs:appinfo>
        </xs:annotation>

        <xs:restriction base="xs:string">
            <xs:enumeration value="BAR"/>
            <xs:enumeration value="BAZ"/>
        </xs:restriction>
    </xs:simpleType>

</xsd:schema>

Or in binding files:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<jaxb:bindings
        xmlns:jaxb="https://jakarta.ee/xml/ns/jaxb" xmlns:xs="http://www.w3.org/2001/XMLSchema"
        xmlns:xjc="http://java.sun.com/xml/ns/jaxb/xjc"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xmlns:annox="http://annox.dev.java.net"
        xsi:schemaLocation="http://java.sun.com/xml/ns/jaxb http://java.sun.com/xml/ns/jaxb/bindingschema_2_0.xsd"
        jaxb:extensionBindingPrefixes="xjc annox"
        version="2.1">

    <jaxb:bindings schemaLocation="schema.xsd" node="/xs:schema">
        <jaxb:bindings node="xs:complexType[@name='issueJIIB39CType']">
            <annox:annotateClass>@jakarta.xml.bind.annotation.XmlRootElement(name="IssueJIIB39CType")</annox:annotateClass>
        </jaxb:bindings>
        <jaxb:bindings node="xs:complexType[@name='issueJIIB39CType']/xs:attribute[@name='test']">
            <annox:annotate target="field">@javax.xml.bind.annotation.XmlAttribute(required=false, name="test")</annox:annotate>
        </jaxb:bindings>
    </jaxb:bindings>

</jaxb:bindings>

You can use the following customization elements in the http://annox.dev.java.net namespace:

annotate with the optional target attribute
package
class
getter
setter
setter-parameter
field
enum-value-method
enum-fromValue-method
annotateProperty
annotatePackage
annotateClass
annotateElement
annotateEnum
annotateEnumConstant
annotateEnumValueMethod - annotate the value() method of the enum
annotateEnumFromValueMethod - annotate the fromValue(String) method of the enum

The http://annox.dev.java.net namespace must be declared in the jaxb:extensionBindingPrefixes attribute via prefix, ex.:

xmlns:annox="http://annox.dev.java.net"
jaxb:extensionBindingPrefixes="xjc annox"

Note: yes, I know that http://annox.dev.java.net no longer exists. Changing this namespace would break old builds. This is just a namespace, there must not necessarily be content there. Treat it as a logical identifier, nothing else.

Removing annotations

Customize your schema using binding files or directly in schema
Add the plugin to the XJC classpath.
Activate the plugin using -XremoveAnnotation-switch.

You can remove annotations using customizations directly in schema:

<xsd:schema
        xmlns:xsd="http://www.w3.org/2001/XMLSchema"
        xmlns:jaxb="https://jakarta.ee/xml/ns/jaxb"
        jaxb:version="3.0"
        xmlns:annox="http://annox.dev.java.net"
        jaxb:extensionBindingPrefixes="annox">

    <xsd:complexType name="FooType">
        <xsd:annotation>
            <xsd:appinfo>
                <annox:removeAnnotation class="jakarta.xml.bind.annotation.XmlType" />
            </xsd:appinfo>
        </xsd:annotation>
        <xsd:sequence>
            <xsd:element name="bar" type="xsd:string"/>
            <xsd:element name="foobar" type="xsd:string">
                <xsd:annotation>
                    <xsd:appinfo>
                        <annox:removeAnnotation class="jakarta.xml.bind.annotation.XmlElement" target="field" />
                    </xsd:appinfo>
                </xsd:annotation>
            </xsd:element>
        </xsd:sequence>
    </xsd:complexType>

</xsd:schema>

Or in binding files:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<jaxb:bindings
        xmlns:jaxb="https://jakarta.ee/xml/ns/jaxb" xmlns:xs="http://www.w3.org/2001/XMLSchema"
        xmlns:xjc="http://java.sun.com/xml/ns/jaxb/xjc"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xmlns:annox="http://annox.dev.java.net"
        xsi:schemaLocation="http://java.sun.com/xml/ns/jaxb http://java.sun.com/xml/ns/jaxb/bindingschema_2_0.xsd"
        jaxb:extensionBindingPrefixes="xjc annox"
        version="2.1">

    <jaxb:bindings schemaLocation="schema.xsd" node="/xs:schema">
        <jaxb:bindings node="xs:complexType[@name='FooType']">
            <annox:removeAnnotation class="jakarta.xml.bind.annotation.XmlType" />
        </jaxb:bindings>
        <jaxb:bindings node="xs:complexType[@name='FooType']//xs:element[@name='foobar']">
            <annox:removeAnnotation class="jakarta.xml.bind.annotation.XmlElement" target="field" />
        </jaxb:bindings>
    </jaxb:bindings>

</jaxb:bindings>

You can use the following customization elements in the http://annox.dev.java.net namespace:

removeAnnotation with the optional target attribute:
package
class
getter
setter
setter-parameter
field
enum-value-method
enum-fromValue-method
removeAnnotationFromProperty
removeAnnotationFromPackage
removeAnnotationFromClass
removeAnnotationFromElement
removeAnnotationFromeEnum
removeAnnotationFromEnumConstant
removeAnnotationFromEnumValueMethod - removes annotation from the value() method of the enum
removeAnnotationFromEnumFromValueMethod - removes annotation from the fromValue(String) method of the enum

The http://annox.dev.java.net namespace must be declared in the jaxb:extensionBindingPrefixes attribute via prefix, ex.:

xmlns:annox="http://annox.dev.java.net"
jaxb:extensionBindingPrefixes="xjc annox"

Using JAXB Annotate Plugin with Maven

Add org.jvnet.jaxb:jaxb-basics-annotate as XJC plugin
Turn on the plugin using -Xannotate or -XremoveAnnotationswitch
Add artifact with your annotations as another XJC plugin

Example:

<plugin>
    <groupId>org.jvnet.jaxb</groupId>
    <artifactId>jaxb-maven-plugin</artifactId>
    <configuration>
        <extension>true</extension>
        <args>
            <arg>-Xannotate</arg>
            <arg>-XremoveAnnotation</arg>
        </args>
        <plugins>
            <plugin>
                <groupId>org.jvnet.jaxb</groupId>
                <artifactId>jaxb-basics-annotate</artifactId>
            </plugin>
            <!-- Artifact with custom annotations -->
            <plugin>
                <groupId>com.acme.foo</groupId>
                <artifactId>my-custom-annotations</artifactId>
            </plugin>
        </plugins>
    </configuration>
</plugin>

See this example.

Note that annotations are first compiled in the annotations module and the added to the classpath of the jaxb-maven-plugin in the schema module:
