Anyone migrate 'wsimport' into pom.xml's maven-antrun-plugin???

[CorbaTheGeek]

I'm using a JAX-WS client for my Spring-WS app. I modeled my use of Jax-WS on the 'airilne' sample's jaxws client and, therefore, run the 'wsimport' generation of client sources from a standalone Ant build file.

I'd like to migrate that 'wsimport' Ant task into my pom.xml file so that I can 'generate-sources', client artifacts and unit tests from the same place.

However, when I migrate the "Mavenified" build.xml file over to plain old Ant 'generate-client-sources.xml' build file, I cannot seem to get addressability to any of the built-in Maven classpath variables. I get several variations on the "Reference maven.plugin.classpath not found." error message depending on whether I'm trying to use the 'maven.compile.classpath', 'maven.plugin.classpath', 'maven.test.classpath',... (with corresponding changes to the <dependencies> of course!)

Here is an example of my attempt to get the plugin's variation working.

Here is the Ant file I'm trying to run under Maven 2.0.5:

<?xml version="1.0"?>
<project name="jaxws-client-targets" default="generate-client-sources">
    <property name="target.dir" value="target"/>

    <target name="init"
            description="Set up environ for 'wsimport' generate-sources.">
        <mkdir dir="${target.dir}/classes"/>
        <mkdir dir="${target.dir}/generated-sources/main/java"/>
    </target>

    <target name="generate-client-sources" depends="clean,init">
        <taskdef name="wsimport" classname="com.sun.tools.ws.ant.WsImport"
                 classpathref="maven.plugin.classpath"/>
        <wsimport wsdl="${basedir}/src/main/webapp/testapp.wsdl"
                  destdir="${target.dir}/classes"
                  package="com.testapp.ws.client"
                  verbose="true"
                  keep="true"
                  sourceDestDir="${target.dir}/generated-sources/main/java"/>
    </target>

    <target name="clean">
        <delete dir="${target.dir}/classes/com/testapp/ws/client"/>
        <delete dir="${target.dir}/generated-sources/main/java/com/testapp/ws/client"/>
    </target>

</project>

using the 'maven.plugin.classpath' as described on the maven-antrun-plugin webpage, and modify the pom.xml file accordingly:

    <build>
        ...
        <plugins>
            <plugin>

            </plugin>
        </plugins>
    </build>

Note that I've migrated the artifacts from the original Ant file's:

<artifact:dependencies pathId="generate.classpath">

to 'dependencies' under the <plugin>.

When I run this, I get that 'maven.plugin.classpath' is not found:

and when I try the bug workaround (reassign the 'maven.plugin.classpath' variable to an Ant file property), I get the same problem.

Has anyone been successful in getting the 'wsimport' Ant task to work under Maven? If so, can you post some working snippets? TIA.

[CorbaTheGeek]

I ended up having to actually MOVE the <target> code from the Ant file into the pom.xml file in order to have the maven.compile.classpath be recognized. I guess that's a feature...?

Here's the pom.xml snippet that performs the 'wsimport':

...
            <plugin>

                            <tasks>
                                <property name="target.dir" value="target"/>

                                <delete dir="${target.dir}/classes/com/testapp/ws/client"/>
                                <delete dir="${target.dir}/generated-sources/main/java/com/testapp/ws/client"/>

                                <mkdir dir="${target.dir}/classes"/>
                                <mkdir dir="${target.dir}/generated-sources/main/java"/>

                                <taskdef name="wsimport" classname="com.sun.tools.ws.ant.WsImport"
                                         classpathref="maven.compile.classpath"/>
                                <wsimport wsdl="${basedir}/../webservices/src/main/webapp/testapp.wsdl"
                                          destdir="${target.dir}/classes"
                                          package="com.testapp.ws.client"
                                          verbose="true"
                                          keep="true"
                                          sourceDestDir="${target.dir}/generated-sources/main/java"/>
                            </tasks>
                            <sourceRoot>${project.build.directory}/generated-sources/main/java</sourceRoot>
                        </configuration>
                        <goals>
                            <goal>run</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
...

with the <dependencies> as listed in the previous post.

This generates the JAX-WS client code correctly. The downside of this approach is that the Maven2 documentation strongly recommends using an external Ant file instead of embedding that <target> Ant code inside the pom.xml. Oh well.

Anyone find a cleaner solution?

[Arjen Poutsma]

I don't like to point out the obvious, but have you tried the JAX-WS Maven2 plugin? See https://jax-ws-commons.dev.java.net/jaxws-maven-plugin/

[CorbaTheGeek]

Maybe I'm confused as to the versions being used. I thought you said that JAXB1 wasn't supported by any known Maven plugin:

UnsupportedOperationException in Jaxb1Marshaller.initJaxbUnmarshaller

[Arjen Poutsma]

Now I'm confused as well: I thought you were talking about building a JAX-WS client. I meant that you can use the JAX-WS maven2 plugin on the client-side.

[CorbaTheGeek]

No, you're right. I have been suffering from the version dissonance between the airline server and the clients. :-/ I will try out the JAX-WS plugin.

BTW, what were your reasons for using a back-level of the JAXB libraries for the server side of the airline sample? Why not just use the latest and greatest libs?

[Arjen Poutsma]

Simple: when I wrote the airline sample, JAX-WS 2 was not out yet . I'm working on a new version of the airline sample, though, using JAXB2 instead of JAXB1, JPA instead of Hibernate, and also use the new Spring-WS annotations.

That would be great!

I just plugged the jaxws-maven-plugin into my pom.xml and voilà! It works. Much easier. Thanks!

The next time I'm tempted to use the maven-antrun-plugin, someone please shoot me!
