Bug fix
I'm running Ubuntu 10.10 on a MacBook Pro with a shared HFS+ partition (so I
can see files under both OS X and Ubuntu). When I try to use FileSets pointing
to files on the HFS+ partition, the sets appear empty. For example:
<project name="ant-bug" default="test">
<property name="dir" value="."/> <!-- default to "." -->
<target name="test">
<fileset id="files" dir="${dir}" includes="*"/>
<property name="filenames" refid="files"/>
<echo message="Files in ${dir}: ${filenames}"/>
</target>
</project>
If this script appears in build.xml in the current directory, its output
depends on whether the current directory is on the HFS+ partition or the system
ext4 partition.
I found another user observing this problem in a mailing list post, but without
any resolution:
<http://mail-archives.apache.org/mod_mbox/ant-user/200908.mbox/%3c1250181030.8090.27.ca...@iggy%3e>
I've tracked the problem to a bug in the java.io.File API as implemented by
OpenJDK. Rather than returning "null" from File.list(), it returns an empty
array. I've submitted a bug report to OpenJDK.
In the mean time (and for backwards compatibility with broken JDKs), the
attached simple patch will prevent the bug from having an impact on Ant users.
