I am comparing 2 folders A and B, and wanted to delete folders and jars present in B which are not present in folder A.
I have written the logic to get needed files to delete, but i do not wanted to delete the directory and jars starting with "com.ibm".
For that I have written delete task as below:
<delete>
<dirset dir="D://mypath/plugins<Filename to delete> excludes="**/com.ibm.*/**" />
</delete>
I have tried the excludes with the scenarios like:
excludes="**/com.ibm.*/**"
excludes="**/com.ibm.*"
excludes="com.ibm.*"
excludes="com.ibm.*/**"
But nothing works for me (It is not deleting any folders/files). Any help would be highly appreciated. Thanks !
you should use fileset instead and specify includeemptydirs="true" of delete.
<project default="init" name="My Project">
<target name="init">
<delete verbose="true" includeemptydirs="true">
<fileset dir="/home/guest/Desktop/plugins" defaultexcludes="no">
<exclude name="com.ibm.*"/>
<exclude name="com.ibm.*/**"/>
</fileset>
</delete>
</target>
</project>
I have an Ant build file, and I try to execute it in the command line with the following command:
$ C:\Program Files (x86)\.....>ant -f C:\Silk4J\Automation\iControlSilk4J\build.xml
But nothing happens, and the result is:
BUILD SUCCESSFUL
Total time: 0 seconds
My environment variable is correct.
What is the problem? Here is my build file:
<?xml version="1.0" encoding="UTF-8" standalone="no"?>

Go to the Ant website and download. This way, you have a copy of Ant outside of Eclipse. I recommend to put it under the C:\ant directory. This way, it doesn't have any spaces in the directory names. In your System Control Panel, set the Environment Variable ANT_HOME to this directory, then pre-pend to the System PATHvariable, %ANT_HOME%\bin. This way, you don't have to put in the whole directory name.
Assuming you did the above, try this:
C:\> cd \Silk4J\Automation\iControlSilk4J
C:\Silk4J\Automation\iControlSilk4J> ant -d build
This will do several things:
It will eliminate the possibility that the problem is with Eclipe's version of Ant.
It is way easier to type
Since you're executing the build.xml in the directory where it exists, you don't end up with the possibility that your Ant build can't locate a particular directory.
The -d will print out a lot of output, so you might want to capture it, or set your terminal buffer to something like 99999, and run cls first to clear out the buffer. This way, you'll capture all of the output from the beginning in the terminal buffer.
Let's see how Ant should be executing. You didn't specify any targets to execute, so Ant should be taking the default build target. Here it is:
<target depends="build-subprojects,build-project" name="build"/>
The build target does nothing itself. However, it depends upon two other targets, so these will be called first:
The first target is build-subprojects:
<target name="build-subprojects"/>
This does nothing at all. It doesn't even have a dependency.
The next target specified is build-project does have code:
<target depends="init" name="build-project">
This target does contain tasks, and some dependent targets. Before build-project executes, it will first run the init target:
<target name="init">
<mkdir dir="bin"/>
<copy includeemptydirs="false" todir="bin">
<fileset dir="src">
<exclude name="**/*.java"/>
</fileset>
</copy>
</target>
This target creates a directory called bin, then copies all files under the src tree with the suffix *.java over to the bin directory. The includeemptydirs mean that directories without non-java code will not be created.
Ant uses a scheme to do minimal work. For example, if the bin directory is created, the <mkdir/> task is not executed. Also, if a file was previously copied, or there are no non-Java files in your src directory tree, the <copy/> task won't run. However, the init target will still be executed.
Next, we go back to our previous build-project target:
<target depends="init" name="build-project">
<echo message="${ant.project.name}: ${ant.file}"/>
<javac debug="true" debuglevel="${debuglevel}" destdir="bin" source="${source}" target="${target}">
<src path="src"/>
<classpath refid="iControlSilk4J.classpath"/>
</javac>
</target>
Look at this line:
<echo message="${ant.project.name}: ${ant.file}"/>
That should have always executed. Did your output print:
[echo] iControlSilk4J: C:\Silk4J\Automation\iControlSilk4J\build.xml
Maybe you didn't realize that was from your build.
After that, it runs the <javac/> task. That is, if there's any files to actually compile. Again, Ant tries to avoid work it doesn't have to do. If all of the *.java files have previously been compiled, the <javac/> task won't execute.
And, that's the end of the build. Your build might not have done anything simply because there was nothing to do. You can try running the clean task, and then build:
C:\Silk4J\Automation\iControlSilk4J> ant -d clean build
However, Ant usually prints the target being executed. You should have seen this:
init:
build-subprojects:
build-projects:
[echo] iControlSilk4J: C:\Silk4J\Automation\iControlSilk4J\build.xml
build:
Build Successful
Note that the targets are all printed out in order they're executed, and the tasks are printed out as they are executed. However, if there's nothing to compile, or nothing to copy, then you won't see these tasks being executed. Does this look like your output? If so, it could be there's nothing to do.
If the bin directory already exists, <mkdir/> isn't going to execute.
If there are no non-Java files in src, or they have already been copied into bin, the <copy/> task won't execute.
If there are no Java file in your src directory, or they have already been compiled, the <java/> task won't run.
If you look at the output from the -d debug, you'll see Ant looking at a task, then explaining why a particular task wasn't executed. Plus, the debug option will explain how Ant decides what tasks to execute.
See if that helps.
Try running all targets individually to check that all are running correct
run ant target name to run a target individually
e.g. ant build-project
Also the default target you specified is
project basedir="." default="build" name="iControlSilk4J"
This will only execute build-subprojects,build-project and init
is it still actual?
As I can see you wrote <target depends="build-subprojects,build-project" name="build"/>, then you wrote <target name="build-subprojects"/> (it does nothing). Could it be a reason?
Does this <echo message="${ant.project.name}: ${ant.file}"/> print appropriate message? If no then target is not running.

We want to loop through directory structure in ant without using foreach .
Is there any elegant way to do the same ?
The apply task can iterate over a set of directories or files
<target name="run-apply">
<apply executable="echo">
<dirset dir="src"/>
</apply>
</target>
I personally like the groovy ANT task
<target name="run-groovy">
<taskdef name="groovy" classname="org.codehaus.groovy.ant.Groovy"/>
<dirset id="dirs" dir="src"/>
<groovy>
project.references.dirs.each {
ant.echo it
}
</groovy>
</target>
The installation of the task jar is easily automated:
<target name="install-groovy">
<mkdir dir="${user.home}/.ant/lib"/>
<get dest="${user.home}/.ant/lib/groovy-all.jar" src="http://search.maven.org/remotecontent?filepath=org/codehaus/groovy/groovy-all/2.1.1/groovy-all-2.1.1.jar"/>
</target>
Finally if you're iterating thru other build files, the subant task is very useful:
<target name="run-subant">
<subant>
<fileset dir="src" includes="**/build.xml"/>
</subant>
</target>
Short answer: Not really. There are ways around this, but I prefer the ant-contrib <for/> task for clarity and simplicity. With the <local/> task, you can now localize values of variables. Before, you sometimes had to use ant-contrib's <var/> task to reset the values, so you could loop through them over and over.
<for param="directory">
<fileset dir="${some.dir}"/>
<sequential>
<local name="foo"/>
<local name="bar"/> <!-- Properties that may change with each iteration -->
<!-- Here be dragons -->
</sequential>
</for>
It's clean, simple, and easy to understand. The big issue many people have with Ant Contrib is that not everyone may have it installed in their $ANT_HOME/lib directory. Far enough. So, if you use ant-contrib, put it as part of your project.
I'll put the ant-contrib jar in ${basedir}/antlib/antcontrib and then put this in my program:
<taskdef resource="net/sf/antcontrib/antlib.xml">
<classpath>
<fileset dir="${basedir}/antlib/antcontrib"/>
</classpath>
</taskdef>
Now, when someone checks out my project, they have ant-contrib already installed (since it's inside my project) and accessible (since I point my <taskdef> task at the location of ant-contrib.jar in my project).
I have next trouble. I have one folder("FirstFolder") and 3 subfolders("1", "2", "3"). I want to archive this folders in next - 1.acp, 2.acp, 3.acp and placed in other folder. It's important - I do not know what are called sub-folders and their number!!! I don't found solutions for this and write simple ant task-
<target name="start">
<foreach target="zipAcp" param="Files">
<path>
<dirset dir="src/main/bootstrap"/>
</path>
</foreach>
</target>
<target name="zipAcp">
<zip destfile="target/classes/alfresco/extension/agilent/${Files}.acp" basedir="src/main/bootstrap"/>
</target>
But i don't know how get directory name(1), but not full path as now(D:\test\1).
You can use the basename task for getting directory name.
I need to write an ant task to selectively delete files.
In a directory, I have the following jars:
acme.jar
acme-201105251330.jar
I want to delete acme.jar because acme-*.jar exists.
Here's what I've tried:
<target name="-check-use-file">
<available property="file.exists">
<filepath> <fileset dir=".">
<include name="./test-*.jar"/> </fileset>
</filepath>
</available>
</target>
<target name="use-file" depends="-check-use-file" if="file.exists">
<!-- do something requiring that file... -->
</target>
Thanks
Have a look at If/Unless Attributes, examples given there seem to be exactly what you are looking for.
