How to reach the parent folder with Ant - ant

I have these path I receive from an application :
D:\bamboo\remoteagent_prod\xml-data\build-dir\STUDIO-STUDIO-MYJOB
I have want to delete all files containing in
D:\bamboo\remoteagent_prod\xml-data\build-dir\
So I have to reach the parent folder.
That's what I have D:\....\build-dir\STUDIO-STUDIO-MYJOB and that's what I want D:\....\build-dir\.
How can I do that with ANT?

<property name="path" location="D:/temp/any"/>
<property name="parent.path" location="${path}/.."/>
<echo message="path: ${path}; parent: ${parent.path}" />
Creates the output:
[echo] path: D:\temp\any; parent: D:\temp

How to get the user temp directory in ant

I can use %tmp% to get the user temp directory in batch file. How can I get the user temp directory in ant?
As a followup to a previous answer, you can access the user's environment variables and use the value from TMP or TEMP:
<project name="test" default="showtemp">
<property environment="env"/>
<target name="showtemp">
<echo message="TMP=${env.TMP}"/>
</target>
</project>
Perhaps a better method would be to use the java system property java.io.tmpdir
<project name="test" default="showtemp">
<target name="showtemp">
<echo message="java.io.tmpdir=${java.io.tmpdir}"/>
</target>
</project>
The tempfile task can be used to create temporary files and directories.
Don't forget ANT is a Java program to access to the windows temporary directory would be platform specific. You could try access it using the environment variables:
<propety environment="env"/>
<echo message="windows tmpdir=${env.tmp}"/>

Change baseDir attribute while using import tag

Let me first provide the background of the problem I'm facing.
I have a directory structure as below.
c:\myDirectory
c:\myDirectory\Project1
c:\myDirectory\Scripts
Under the c:\myDirectory\Scripts there is a script that download the source code (from svn) and creates the c:\myDirectory\Project1 directory.
I have another ant scripts ( c:\myDirectory\Scripts**compile-source.xml ) that compiles the Project1
from an ant script build.xml that is downloaded to c:\myDirectory\Project1
Snippet for c:\myDirectory\Scripts\compile-source.xml
<project name="compile" default="buildAll" basedir=".">
<property file=".\build.properties">
</property>
.......
<import file="${project.home.path}/${project.name}/build.xml"/>
<target name="buildAll">
<antcall target="jar-pack"/>
</target>
</project>
Snippet for c:\myDirectory\Project1\build.xml.
<project name="CommonFeatures" default="jar-pack" basedir=".">
<description>
A build file for the Common Features project
</description>
....
</project>
Note that the basedir for the project is set as "." for both the above ant scripts.
When I execute the script c:\myDirectory\Scripts\compile-source.xml from the c:\myDirectory\Scripts directory the target "jar-pack" present in the c:\myDirectory\Project1\build.xml gets executed.
However, the problem is that basedir attribude in build.xml ( basedir="." ) is the current working directory and in this case its c:\myDirectory\Scripts. Hence the script build.xml errors out since the basedir for build.xml is expected to be c:\myDirectory\Project1. The build.xml script would have worked, if basedir="." were set to "c:\myDirectory\Project1", but unfortunately build.xml file comes from the source code that is downloaded and I'm unable to edit.
So here's my question, Is it possible to do any of the following.
Override the value of the attribude basedir="." in build.xml when the is done in c:\myDirectory\Scripts\compile-source.xml ?
Is it possible to change the basedir in build.xml by any other mechanism so that the script c:\myDirectory\Project1\build.xml is executed under directory c:\myDirectory\Project1 ?
Any other way to resolve this issue?
Any help from Ant experts to overcome this issue is highly appreciated.
You can update basedir using subant task. Check this answer
Create the following build.xml file (assuming it is in Z:/any/folder):
<?xml version="1.0" encoding="UTF-8"?>
<project name="project">
<target name="mytarget">
<subant target="debug">
<property name="basedir" value="X:/any/dir/with/project"/>
<fileset dir="Y:/any/folder/with" includes="build.xml"/>
</subant>
</target>
</project>
The you can execute ant mytarget from Z:/any/folder
You can specifically reference the location of your build file, which is described in this stack overflow thread. This would allow you to get and use the directory your build file resides in as a reference point.
For your case the usage of the subant or ant tasks may be better suited, but nevertheless...
You can (but you should know/consider the side-effects!) extend ant with the common ant-contrib task definitions and use the var task which is able to override properties. Make sure to use the latest version (> 1.0b3).
<!-- adjust to your path and include it somewhere at the beginning of your project file -->
<taskdef resource="net/sf/antcontrib/antlib.xml" classpath="lib/ant-contrib-1.0b3.jar" />
<!-- works e.g. for basedir = /foo/bar to update it to /foo/bar/.. ~ /foo -->
<var name="basedir" value="${basedir}/.." />
update: but one has to be careful, because this does not change . (current working directory) (so <property name="x" location="tmp" /> would be relative to . and not to basedir anymore ; update: setting basedir outside of ant or via <project basedir= also sets . to basedir!). Here is some test target proving the effect on both:
<target name="tst.dummy.basedir-override">
<!-- example output:
tst.dummy.basedir-override:
[echo] basedir before: basedir=D:\tst, '.'=D:\tst\.
[echo] updating it via 'var' to '..'
[echo] basedir now: basedir=D:\tst/.., '.'=D:\tst\.
-->
<property name="cur" location="." /> <!-- makes the relative path absolute -->
<echo message="basedir before: basedir=${basedir}, '.'=${cur}" />
<echo message="updating it via 'var' to '..'" />
<var name="basedir" value="${basedir}/.." />
<property name="cur2" location="." /> <!-- makes the relative path absolute -->
<echo message="basedir now: basedir=${basedir}, '.'=${cur2}" />
</target>

Get immediate subdirectory of a root directory containing a subdirectory

I have a following directory structure
root_dir
fixed_dir
random_dir
subdir1
subdir2
subdir2.1
subdir3
subdir3.1
subdir3.2
In the ANT build file I know the root_dir, fixed_dir, and one directory that is either random_dir or a subdirectory below random_dir (subdirX). I need to determine the path of random_dir given some subdirX. Is it possible to find this directory in ANT and if so, how?
Here is a tested solution for finding the immediate subdirectory of a root directory that contains some subdirectory subdirX at any level of nesting given the file structure provided in the question.
<property name="root.dir" location="${basedir}/root_dir" />
<property name="subdirX" value="subdir2.1" />
<target name="find-immediate-subdir-of-root-containing-subdirX">
<dirset dir="${root.dir}" includes="**/${subdirX}" id="mydirset" />
<pathconvert property="random_dir" pathsep="${line.separator}" refid="mydirset">
<mapper type="regexp"
from="^(${root.dir}${file.separator}[^${file.separator}]+).*"
to="\1"/>
</pathconvert>
<echo message="${random_dir}" />
</target>
Output
find-immediate-subdir-of-root-containing-subdirX:
[echo] /ant/project/basedir/root_dir/random_dir

With Ant addon Flaka you'll get the parent as property of a file object (see Flaka Manual, section 3.7.2, i.e.
<project xmlns:fl="antlib:it.haefelinger.flaka">
<!-- let standard ant tasks, i.e. echo
understand EL expresssions -->
<fl:install-property-handler />
<echo>#{file('${basedir}').parent}</echo>
<!-- or without fl:install-property-handler use fl:echo-->
<fl:echo>#{file('${basedir}').parent}</fl:echo>
</project>
so you would use :
#{file('${yoursubdir}').parent

Ant not excluding files from build

I'm currently building a tar:
<property name="dcc-shell.dir" value="."/>
<property name="dcc-mdp.dir" value="${dcc-shell.dir}/eq-mo-drop-copy-converter-mdp"/>
<property name="mdp-code.dir" value="${dcc-mdp.dir}/*"/>
<property name="mdp-exclude.dir" value="${dcc-mdp.dir}/target"/>
<property name="dcc-srv.dir" value="${dcc-shell.dir}/eq-mo-drop-copy-converter-server"/>
<property name="srv-code.dir" value="${dcc-srv.dir}/src/main/*"/>
<property name="dcc-trans.dir" value="${dcc-shell.dir}/eq-mo-drop-copy-converter-transformer"/>
<property name="trans-code.dir" value="${dcc-trans.dir}/src/main/*"/>
<target name="create MDP.Tar">
<tar destfile="${dcc-shell.dir}/mdp.tar"
excludes="${mdp-exclude.dir}"
basedir="${dcc-mdp.dir}"
/>
</target>
however it continuly keeps adding the target file and it's contents to the tar file dispite specifying the it to be excluded via excludes=dir
You need the "**" to exclude the directory and everything in it. These excludes are file based and not directory based.
<target name="create MDP.Tar">
<tar destfile="${dcc-shell.dir}/mdp.tar"
excludes="${mdp-exclude.dir}/**"
basedir="${dcc-mdp.dir}"
/>
</target>
Its because your relative paths are off, your script is basically doing this:
Include all files from the directory:
./eq-mo-drop-copy-converter-mdp
but dont include this one:
./eq-mo-drop-copy-converter-mdp\target
Which really reads eq-mo-drop-copy-converter-mdp/eq-mo-drop-copy-converter-mdp\target which doesn't exist.
You need to specify exclude .\target\**
Through trial and error I found this to be a solution:
**/target/**

How to turn directories to .jar files with Ant

How to turn a list of directories into a list of .jar files ?
It seems that using Copy Task and Mappers is the right way to do this but I did not find any nested element creating a jar file from a directory.
Of course, the list of directories would be computed and not hard coded in the ant script.
For instance, a foo directory contains bar1, bar2 and bar3 directories. The script would create bar1.jar from the bar1 dir, bar2.jar from bar2 dir and bar3.jar from bar3 dir
The script would create a bar4.jar from a newly added bar4 directory without any change in the script (no hardcoded list).
Thanks ahead for your help
You can use the subant task to do this. For example:
<project name="jars" default="jar" basedir=".">
<property name="dir.build" value="${basedir}/build"/>
<property name="dir.root" value="${basedir}/foo"/>
<target name="init">
<tstamp/>
<mkdir dir="${dir.build}"/>
</target>
<target name="jar" depends="init">
<!-- ${ant.file} is the name of the current build file -->
<subant genericantfile="${ant.file}" target="do-jar">
<!-- Pass the needed properties to the subant call. You could also use
the inheritall attribute on the subant element above to pass all
properties. -->
<propertyset>
<propertyref name="dir.build"/>
</propertyset>
<!-- subant will call the "do-jar" target for every directory in the
${dir.root} directory, making the subdirectory the basedir. -->
<dirset dir="${dir.root}" includes="*"/>
</subant>
</target>
<target name="do-jar">
<!-- Get the basename of the basedir (bar1, bar2, etc.) -->
<basename file="${basedir}" property="jarname"/>
<jar jarfile="${dir.build}/${jarname}.jar" basedir="${basedir}"/>
</target>
</project>
You could use the appropriate Jar task, along with the foreach ant-contrib extension task.
A sample:
<foreach list="${hmProjectsList}" delimiter="/,"
target="cvsCheckOut" param="hmProjectDir" inheritall="true" />
