Count number of files in fileset
Hello,
I have to concat some files from a fileset together into another file. I use
the following fileset for this:
<concat destfile="${build.webservices.dir}/config.xml">
<header><?xml version="1.0" encoding="UTF-8"?>
<configuration xmlns="http://java.sun.com/xml/ns/jax-rpc/ri/config">
</header>
<fileset refid="module-webservices-config-fileset" />
<footer></configuration> </footer>
</concat>
However, this only should hebben if the number of files in fileset
module-webservices-config-fileset > 0.
Is there a way, to fetch the number of files in a fileset (may be with
ant-contrib, or another 3rd-party addon)?
Thanks in advance.
Kind regards,

You can check a fileset is empty using the above, but not count the number
of files. For that you'd need custom code, in Java or in a <script>.
Note that ${toString:referenceId} is still a bit experimental.
Using <property name="foo" refid="referenceId" /> is more traditional (but
Ant 1.6 specific), and for older versions of Ant, use <pathconvert> to
convert the fileset into a string. --DD

In 1.6 you could use the ${toString:} psuedo-property:
<target name="present">
<fileset id="fileset.notpresent" dir="."
includes="*.notpresent"/>
<condition property="no.files.present">
<equals arg1="" arg2="${toString:fileset.notpresent}"/>
</condition>
<echo>no.files.present=${no.files.present}</echo>
<fileset id="fileset.present" dir="."
includes="*.xml"/>
<condition property="no.files.present_2">
<equals arg1="" arg2="${toString:fileset.present}"/>
</condition>
<echo>no.files.present_2=${no.files.present_2}</echo>
</target>

No, this is not true in this case. The <header> and <footer> elements
are independent
of the fileset.

1) Ant 1.7 will contain a <resourcecount> task that
can count files from a fileset.
2) <concat> shouldn't do anything if there are no
existing files.
