How do you include classes from a WAR as a dependency?

Hi,

I'm using Maven 2.2.  I think I read somewhere that you cannot have a WAR as
a dependency because maven doesn't know how to read the WEB-INF/classes
directory.  I am finding this to be true because I have this dependency in
my test project ...

    <dependency>
        <groupId>myco.galc.capitol.tours</groupId>
        <artifactId>myco-galc-capitol-tours</artifactId>
        <version>1.0-SNAPSHOT</version>
        <type>war</type>
    </dependency>

but I am still getting compilation errors complaining that a class cannot be
found that I know to be in my WAR file.  What is the work-around for this? 
That is, how can I include a WAR as a dependency?

Thanks,  - Dave

I just discovered there is a "<sourceDirectory>" element as part of the
"<build>" tag.  So in my test folder, I made the <sourceDirectory> my
webapp's java folder, where the .java files are contained.

Is this the conventional way of doing it?  That prevents me from having to
make a JAR file out of my WAR's classes, but maybe I'm misunderstanding the
purpose of the <sourceDirectory> element.

Thanks, - Dave

This isn't Maven related, it's a Java thing.  Try compiling code at
the command line with a war on the classpath -- it won't work.

If something else depends on the classes in your war, then those
classes probably deserve to be in a separate module which creates a
jar.  Then both your war and the other project can depend on this jar.

You might also be interested in the 'archiveClasses' parameter of the
war plugin, which will make it create a jar instead of using
WEB-INF/classes.
