BindingIncludes doesn't appear to support classpath: or maven: resolvers

[josephhusby]

I spent a long time attempting to resolve a bindings file from another project via classpath: and maven: resolver syntax in the but was not successful. I ensured I had the dependent project listed as both a project and plugin dependency, and I confirmed that the xjb file was where I expected it in the dependent jar. Is this simply not supported or am I doing something wrong?

As a brief summary, this is what I tried:

1. Project groupA:artifactA has datetime.xjb in src/main/resources which puts it in the root of the jar
2. Project groupA:artifactB has the following pom configuration:

	<dependencies>
		<dependency>
			<groupId>groupA</groupId>
			<artifactId>groupB</artifactId>
			<version>1</version>
		</dependency>
	</dependencies>

	<build>
		<plugins>
			<plugin>
				<groupId>org.jvnet.jaxb</groupId>
				<artifactId>jaxb-maven-plugin</artifactId>
				<version>4.0.10</version>
				<configuration>
					<schemaIncludes>
						<schemaIncludes>schema.xsd</schemaIncludes>
					</schemaIncludes>
					<bindingIncludes>
						<include>maven:groupA:groupB!/datetime.xjb</include>
					</bindingIncludes>
				</configuration>
				<dependencies>
					<dependency>
						<groupId>groupA</groupId>
						<artifactId>groupB</artifactId>
						<version>1</version>
					</dependency>
				</dependencies>
			</plugin>
		</plugins>
	</build>

Similarly, I tried <include>classpath:datetime.xjb</include> to no avail.

Hi @josephhusby

Did you try adding <scanDependenciesForBindings>true</scanDependenciesForBindings> to plugin's configuration ?

That should Scan all compile-scoped project dependencies for XML binding files

[josephhusby]

That seems to work! Although now my project fails because both my project and the dependent project have bindings files that have globalBindings. I don't suppose there are any tricks to work around having multiple globalBindings?

[laurentschoelens]

What kind of stuff do you have in your globalBindings section ?

[josephhusby]

In the common project (which many others depend on) I was hoping to have the global bindings to fix the XMLGregorianCalendar dateTime types:

		<jaxb:globalBindings>
			<jaxb:javaType
				name="java.time.LocalDate"
				xmlType="xs:date"
				parseMethod="my.xml.DataTypeAdapter.parseDate"
				printMethod="my.xml.DataTypeAdapter.printDate" />
			<jaxb:javaType
				name="java.time.LocalTime"
				xmlType="xs:time"
				parseMethod="my.xml.DataTypeAdapter.parseTime"
				printMethod="my.xml.DataTypeAdapter.printTime" />
			<jaxb:javaType
				name="java.time.Instant"
				xmlType="xs:dateTime"
				parseMethod="my.xml.DataTypeAdapter.parseDateTime"
				printMethod="my.xml.DataTypeAdapter.printDateTime" />
			<jaxb:javaType
				name="java.time.Duration"
				xmlType="xs:duration"
				parseMethod="my.xml.DataTypeAdapter.parseDuration"
				printMethod="my.xml.DataTypeAdapter.printDuration" />
		</jaxb:globalBindings>

And then some of the individual projects may or may not use things like xjc:simple in their global bindings.

Is it still necessary, even with the latest jaxb tools 4 and jakarta, to write adapters to be rid of XMLGregorianCalendar?

[laurentschoelens]

Yes, XMLGregorianCalendar is still default

What kind of error do you have now ? I don't understand why it fails...

[mattrpav]

XMLGregorianCalendar overcame some of the issues w/ the default java.date class before the new java.time. Sounds like a jaxb-api or jaxb-ri update may be in order =)

[josephhusby]

I get the following error when I have a bindings file in my local project with global bindings, and set scanDependenciesForBindings to true

[ERROR] Error while parsing schema(s).Location [ file:/.../src/main/resources/bindings.xjb{12,24}].
com.sun.istack.SAXParseException2; systemId: file:/.../src/main/resources/bindings.xjb; lineNumber: 12; columnNumber: 24; compiler was unable to honor this globalBindings customization. It is attached to a wrong place, or its inconsistent with other bindings.

Line 12 is the opening jaxb:globalBindings tag. The dependent project also has a bindings file with global bindings. And as far as I've been able to tell in my online research, there can only be one global bindings section as jaxb does not attempt to merge or combine multiple global bindings.

@josephhusby : did you look at wiki's 'Specifying what to compile' page ?

I think you can define configuration like

<binding>
    <url>maven:groupA:groupB!/datetime.xjb</url>
</binding>

like in the schema part (extract from wiki) :

<schema>
    <!-- Specifies a schema in the Maven artifact. -->
    <url>maven:org.jvnet.jaxb2.maven2:maven-jaxb2-plugin-tests-po!/po.xsd</url>
</schema>
