Why is axistools-maven-plugin trying to access this relative schema location?

问题

We're doing a web service project with Axis 1.x and I'm having problems getting the Maven build to work.

I do a

 mvn clean generate-sources

which triggers axistools-maven-plugin's wsdl2java goal. It eventually aborts with

[INFO] [axistools:wsdl2java {execution: generate-project}]
[INFO] about to add compile source root
[INFO] Processing wsdl: C:\Project\src\main\webapp\WEB-INF\wsdl\project.wsdl
Jan 24, 2011 11:24:58 AM org.apache.axis.utils.JavaUtils isAttachmentSupported

[INFO] ------------------------------------------------------------------------

[INFO] Error generating Java code from WSDL.

Embedded error: Error running Axis
C:\Project\src\main\webapp\WEB-INF\project.xsd (The system cannot find the file specified)

This is correct. That file doesn't exist. (And -e yields no additional useful information -- it's a LifecycleExecutionException, caused by a MojoExecutionException, caused by an AxisPluginException, caused by a FileNotFoundException.)

The point is, it shouldn't search for WEB-INF\project.xsd, it should access WEB-INF\wsdl\project.xsd.

Here's what the WSDL says:

<wsdl:types>
    <xsd:schema targetNamespace="http://domain/project/">
        <xsd:import namespace="http://domain/schema/" schemaLocation="project.xsd"/>
    </xsd:schema>
</wsdl:types>

This seems to work fine for all my coworkers. We're all using Maven 2.2.1 and axistools-maven-plugin is pinned to 1.4 with the following configuration:

  <plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>axistools-maven-plugin</artifactId>
    <version>1.4</version>
    <executions>
      <execution>
        <id>generate-project</id>
        <goals>
          <goal>wsdl2java</goal>
        </goals>
        <configuration>
          <sourceDirectory>${basedir}/src/main/webapp/WEB-INF/wsdl/</sourceDirectory>
          <outputDirectory>target/generated-sources</outputDirectory>
          <serverSide>true</serverSide>
          <testCases>false</testCases>
          <wrapArrays>false</wrapArrays>
        </configuration>
      </execution>
    </executions>
  </plugin>

I already completely cleared my local Maven repository, hoping that it was a rogue dependency, but that didn't change anything. Any idea what could be causing this just for me, but not for my coworkers?

EDIT 1: I tried changing the schemaLocation to wsdl/project.xsd (just for testing purposes, I won't be able to make any permanent modifications to the WSDL) and got this amusing result:

Embedded error: Error running Axis
WSDLException (at /wsdl:definitions/wsdl:types/xsd:schema):
    faultCode=OTHER_ERROR: An error occurred trying to resolve
    schema referenced at 'wsdl\project.xsd', relative to
    'file:/C:/Project/src/main/webapp/WEB-INF/wsdl/project.wsdl'.:
    This file was not found:
    file:/C:/Project/src/main/webapp/WEB-INF/wsdl/wsdl/project.xsd

If you are, like me, now thinking that maybe ./project.xsd might work... nope, sorry, that makes it search directly for WEB-INF/project.xsd again.

EDIT 2: Okay, now axistools is just teasing me...

../project.xsd
--> src/main/webapp/project.xsd (wrong)

../wsdl/project.xsd
--> src/main/webapp/wsdl/project.xsd (wrong)

../WEB-INF/wsdl/project.xsd
--> src/main/webapp/WEB-INF/WEB-INF/wsdl/project.xsd (wrong)

As a reminder, the correct path would be src/main/webapp/WEB-INF/wsdl/project.xsd.

回答1:

Try to use the useEmitter tag like:

    <plugins>
        <plugin>
            <groupId>org.codehaus.mojo</groupId>
            <artifactId>axistools-maven-plugin</artifactId>
            <version>1.4</version>
            <configuration>
                <useEmitter>true</useEmitter>

...

回答2:

I was able to resolve this issue by ensuring that the path of the project location does not contain spaces. Therefore, the default location on Win XP will not work ("Documents and Settings")

回答3:

Unfortunately when <useEmitter> is enabled <subPackageByFileName> feature does not work anymore.

So I had to split generation into two "executions"

first all WSDLs without XSD and with <subPackageByFileName>true</subPackageByFileName>
and then the one with XSD include (luckily I have just one) with <useEmitter>true</useEmitter> (and the file name explicitly added to <packageSpace>)

回答4:

I also got the same issue while building with maven as mentioned and I was able to resolve this issue by ensuring that the path of the project location does not contain spaces.
