OutOfMemory...

[Alan Brown <ab...@symyx.com>]

I'm using <subant> with genericAntFile to run an ant task against every
subdirectory.  However, it runs out of memory before finishing.  I've
done some poking around and it seems that <subant> like <antcall> has
some issues with the classLoader that can result in this kind of
problem.  Does anyone know a workaround?  I really want to be able to
use <subant> with genericAntFile if I can, as it really suits my
problem, but my problem isn't well suited to having the task run out of
memory before completion...

Ps.  Here's my code...

PPS. The custom and task that I wrote is 'null'ed at the end of each use
and I call System.gc() (in hope more than expectation)



<subant target="generateSrcAndSchema"
genericantfile="sourceCodeBuild.xml"

            inheritall="true"

            failonerror="false">

            <dirset dir="${build}">

                <include name="*"/>

            </dirset>

        </subant>

<target name="generateSrcAndSchema" depends="defineRc">

            <basename property="currentDir" file="${basedir}"/>

            <rc jar="${schema.jar}"

                  copyright="${schema.copyright}"

                  generateDropScript="false"

                  sqldir="${oraDir}/"            

                  metadatadir="${metadataDir}"

                  schemadir="schema"

                  proxydir="${proxyDir}"

                  generateProxies="true"

                  schemaName="${currentDir}2">

               

                <fileset dir=".">

                   <include name="**/*.meta"/>

                </fileset>

            </redc>

    </target>

<target name="defineRc">

                 classpathref="rc.classpath"

Try using <macrodef> ... I encountered that problem from a while ago, and 
<macrodef> seem to have fixed the problem.

You could try placing the taskdef in the top level build
file.
