| AW: Count number of files in fileset | AW: Count number of files in fileset 2005-06-14 - By Jan.Materne@(protected)
You could count the files with
<scriptdef name="count" language="javascript">
<attribute name="property"/>
<element name="fileset" type="fileset"/>
<![CDATA[
filesets = elements.get("fileset");
propname = attributes.get("property");
number = 0;
for (i = 0; i < filesets.size(); ++i) {
number = number + filesets.get(i).getDirectoryScanner(project)
.getIncludedFiles().length;
}
project.setProperty(propname, number);
]]>
</scriptdef>
<count property="c1">
<fileset dir="."/>
</count>
<echo>All files here : ${c1}</echo>
> I have to concat some files from a fileset together into another file.
> However, this only should hebben if the number of files in fileset
> module-webservices-config-fileset > 0.
What do you expect with 'module-webservices-config-fileset = 0'? You could
<copy>/<echo> a
"zero-file" in that case.
