Lewis,
By command line params, I mean what params does GoraCompiler require (can
I see examples as if you'd manually execute from command line)...

Martin,
I don't know the GoraCompiler at all. Again, I was just guessing what he
might need to do :)
Lewis,
Can you provide either a doc link or some of the command line params that you
need?

GoraCompiler should implement space delimiter for folders instead of colon

Subject: Re: Correct configuration for reading a list into a Java class
I don't know the GoraCompiler nor any of its command line arguments...
But have you tried the java <arg line=""> sub element? I don't know if it
will help you but this may work:
<java classname="org.apache.gora.compiler.GoraCompiler" fork="true">
<classpath refid="classpath"/>
<arg line="${goraavscfiles} ${src.dir}"/>
</java>
I did a minor bit of googling - but didn't quickly find the command line
options or I may have had a firmer "I think this will work" statement :)

Hi All,
I've done a fiar bit of digging on this one on user@ archives and
there have been various threads on the topic. I understand that the
solution to reading in multiple files an executing them with the java
element is a custom solution. The problem is pretty simple. I have a
directory of avro schemas which I would like to pass to a GoraCompiler
class to be compiled.
So far I've got
<!-- ====================================================== -->
<!-- Generate the Java files from the GORA schemas -->
<!-- Will call this automatically later -->
<!-- ====================================================== -->
<!-- map for the gora .avsc files contained in ./src/gora/
so they can be passed as a list to the GoraCompiler
via the generate-gora-src target -->
<fileset dir="${gora.avsc.dir}" id="gora.avsc.files">
<include name="*.avsc"/>
</fileset>
<pathconvert property="goraavscfiles" refid="gora.avsc.files">
<map from="${goraavscdir}" to=""/>
</pathconvert>
<target name="generate-gora-src"
description="> generate the Java files from the Gora schema(s) in
src/gora/*.avsc">
<java classname="org.apache.gora.compiler.GoraCompiler" fork="true">
<classpath refid="classpath"/>
<arg value="${goraavscfiles}"/>
<arg value="${src.dir}"/>
</java>
</target>
When I execute I get
generate-gora-src:
[java] 12/12/01 16:22:09 INFO compiler.GoraCompiler: Compiling

If someone could please help me to understand how to separate the
files into the required File [] list then that would be great. I
should make it clear that I've discovered pathconvert's pathsep
attribute but it still seems to be a string being passed as oppose to
a separated list of files.
I should also note that making the target accept a single explicit
file works perfectly, so I know my configuration is in the way I'm
constructing the mappings.
Thanks very much in advance
Lewis
