DefaultValuePlugin: IllegalArgumentException when elements come with an inline anonymous type definition

[mgrobarek]

I’m currently migrating to your default value xjc plugin when I encountered the following problem:

[main] INFO org.jvnet.basicjaxb.plugin.defaultvalue.DefaultValuePlugin - XJC> XdefaultValue: : Start

  Verbose.: true

This happens for the following element definition:

<xsd:element name="Limit" default="1000" minOccurs="0">
    <xsd:simpleType>
        <xsd:restriction base="xsd:int">
            <xsd:minInclusive value="1" />
            <xsd:maxInclusive value="10000" />
        </xsd:restriction>
    </xsd:simpleType>
</xsd:element>

The simpleType used for the Limit element has no name, hence the QName cannot be instantiated in DefaultValuePlugin.java:325.
I can work around this issue by adding an explicit name for the inline type in my XSD, like this: <xsd:simpleType name="LimitInt">

But in my case, the XSD comes from outside my project and I can’t change it on my own. Hence it would be nice to have the DefaultValuePlugin to ignore such empty names.

I’m using:

• org.patrodyne.jvnet:hisrc-basicjaxb-plugins:2.2.0
• org.glassfish.jaxb:jaxb-xjc:4.0.4
• org.apache.cxf:cxf-tools-wsdlto-core:4.0.3
• Eclipse Temurin 17.0.9+9

Thank you for reporting this issue. A new commit 5be585a includes your Limit example, in the unit test, and a modification to DefaultValuePlugin to handle anonymous types. It will be included in the next release (no ETA).

Hello,

I faced the same issue and default value is a key featurefor me.
When is planned version 2.2.1 ?

Many thanks

[patrodyne]

I believe the current release period will be shorter than past periods. Note: I refrain from guessing ETAs.

[patrodyne]

The DefaultValuePlugin has been released to Maven Central.

[SebGuillomon]

Thanks for release,

Using Maven plugin "org.patrodyne.jvnet:hisrc-higherjaxb-maven-plugin:2.2.0" with this dependency (only this release available), I have this error

[ERROR] Failed to execute goal org.patrodyne.jvnet:hisrc-higherjaxb-maven-plugin:2.2.0:generate (default) on project plma-tools-commons: Execution default of goal org.patrodyne.jvnet:hisrc-higherjaxb-maven-plugin:2.2.0:generate failed: An API incompatibility was encountered while executing org.patrodyne.jvnet:hisrc-higherjaxb-maven-plugin:2.2.0:generate: java.lang.NoSuchMethodError: 'boolean org.jvnet.basicjaxb.util.FieldUtils.isConstantField(com.sun.tools.xjc.outline.FieldOutline)'

[patrodyne]

The hisrc-higherjaxb-maven-plugin v2.2.1 should be available to you.
