Repeating a task for a list of directories
Hi,
I have not done too much with Ant, but I would like to find all
sub-directories below a given directory and then for each directory repeat a
task in the context of that directory, so for example
topdir
subdir1
subdir2
I would like to get ant to repeat a task for subdir1 and subdir2 and have
access to the directory name within the task - does anyone know how I can
achieve this?
Cheers,
Rob.

The first has a "/" in front of the lib.
-> this is an absolute path.

I thought I would give some feedback, it seems that I made two mistakes...
1) I typed the incorrect version number, so this was why it could not find
the explicitly named jar file.
2) even after fixing the jar name this syntax did not work...
<taskdef resource="net/sf/antcontrib/antlib.xml">
<classpath>
<pathelement location="/lib/ant/ant-contrib-1.0b3.jar"/>
</classpath>
</taskdef>
(yes I did correct the jar name by this point!)
but this did work...
<taskdef resource="net/sf/antcontrib/antlib.xml">
<classpath>
<fileset dir="lib/ant" includes="*.jar"/>
</classpath>
</taskdef>
Does anyone know what was wrong with the first one?
Cheers,
Rob.

Yes,
normally I keep a lib/ant/-plugin-name-/(jars needed for the plugin)
directory structure and have a ant-contrib.xml importable file to
configure the plugin:
<project name="ant-contrib"
xmlns:ac="antlib:net.sf.antcontrib">
<typedef uri="antlib:net.sf.antcontrib"
resource="net/sf/antcontrib/antlib.xml">
<classpath>
<fileset dir="lib/ant/ant-contrib" includes="*.jar"/>
</classpath>
</typedef>
<presetdef name="bash" uri="antlib:net.sf.antcontrib">
<ac:shellscript shell="bash"/>
</presetdef>
</project>
(note that for ant 1.7.0 you do not need to specify resource when the
uri is an antlib:)

You should put ant-contrib.jar into your project svn and let the buildfile refer to that (local) location.
PROJECT
| build.xml
+-- lib/ant
+-- ant-contrib.jar
build.xml
---------
<project xmlns:ac="antlib:net.sf.antcontrib">
<taskdef uri="antlib:net.sf.antcontrib"
resource="net/sf/antcontrib/antlib.xml"
classpath="lib/ant/ant-contrib.jar"/>
<ac:for param="i" begin="1" end="3">
<sequential>
<echo>i: ${i}</echo>
</sequential>
</ac:for>
</project>

Re: Repeating a task for a list of directories
Posted by Rob Wilson <ne...@gmail.com>.
Thanks for the information, I believe I need ant-contribs foreach such that
I can do some processing for each subdirectory. I've downloaded the jar
file and would prefer not to copy it directly into Ant libs folder, such
that the next person to do a svn update can run with it without having to
think about it.
However, the documentation on sourceforge is not explaining how to do this
(the homepage version http://ant-contrib.sourceforge.net/ contains less
information than the other tasks section (
http://ant-contrib.sourceforge.net/tasks/index.html).
Basically, trying to work out whether I need to reference the .xml or
.properties reference, and where it exists - it complains it can't find it,
but it's not in the .zip file downloaded... Am I meant to create it? What's
in it? Help! ;-)
It states....
Keep ant-contrib-version.jar in a separate location. You now have to tell
Ant explicitly where to find it (say in /usr/share/java/lib):
<taskdef *resource="net/sf/antcontrib/antlib.xml*">
<classpath>
<pathelement location="/usr/share/java/lib/ant-contrib-version.jar"/>
</classpath>
</taskdef>
If you would like to use run with Ant Version 1.5 you must use the the
.properties file instead. Keep in mind that some tasks will not be available
to you , such as the <for> task:
<taskdef resource="net/sf/antcontrib/antcontrib.properties">
<classpath>
<pathelement location="/usr/share/java/lib/ant-contrib-version.jar"/>
</classpath>
</taskdef>

hi,
if all you are doing is calling a different ant file within each
subdirectory - you can look at subant
(http://ant.apache.org/manual/CoreTasks/subant.html)
If your main build file has a target which you want to repeat for each
subdirectory, use ant-contrib's for or foreach tasks
(http://ant-contrib.sourceforge.net/tasks/tasks/index.html)
With the ant-contrib option, you will have access to a property that you
can define which contains the directory name.
hth,
Vijay
