Yep, I can reproduce what you are seeing. The order of files being read
in (alphabetical/lexical order..) matters in that the
DroolsCompilerAntTask will compile them one at a time:

public class DroolsCompilerAntTask extends MatchingTask {
....
private void createWithKnowledgeBuilder(AntClassLoader loader) throws
FileNotFoundException,
DroolsParserException,
IOException {
...

for ( int i = 0; i < fileNames.length; i++ ) {
// compile rule file and add to the builder
compileAndAddFile( builder,
fileNames[i] );
}

...
}
}

I'll take a look at the code and fix it up in the near future, but for
now what you can do is just as Mic said to put your declared types in
let's say drools.package file and make sure in your ant tasks that they
get read first. In my simple test this worked fine:

<target name="declaredtypes">
<compiler srcdir="ant" tofile="antout/person.rules">

<include name="*.package" />
</compiler>
</target>

<target name="rules" depends="declaredtypes">
<compiler srcdir="ant" tofile="antout/person.rules">

<include name="*.drl" />
<include name="*.brl" />
<include name="*.xml" />
<include name="*.dslr" />
</compiler>
</target>

since all declarations are in drools.package (or person.package or
whatever you want to call it), and making sure that "rules" target
depends on the "declaredtypes" target you can assure your declared types
get read first. Let me know if this helps.

Thanks.
