I tried to get the files name of a folder using the following script
<target name="test1" depends ="init">
<fileset id="appendJars" dir="${ant.dir}/test">
<include name="*.txt" />
</fileset>
<pathconvert property="files" refid="appendJars" pathsep="," />
<echo message="files: ${files}" />
<for list="${files}" param="f">
<sequential>
<echo>#{f}</echo>
<antcall target="test2">
<param name="fileName" value="#{f}" />
</antcall>
</sequential>
</for>
</target>
I get the files name as E:/ant/test/1.txt ...
I wanna just get 1.txt
how to do?
You can use <basename/> task to get file name. More info can be found here.

While going through the scenario what i got is that folder collection of different extension file i have use resource count for all extension if i have 3 different extension file than try to get resource count of all file differ with extension
Eg:
<resourcecount property="firstfile">
<fileset dir="${basedir}">
<include name="*.xml" />
</fileset>
</resourcecount>
<echo message="There are ${firstfile} xml in This Folder ${basedir}" />
<resourcecount property="SecondFile">
<fileset dir="${basedir}">
<include name="*.jar" />
</fileset>
</resourcecount>
<echo message="There are ${SecondFile} xml in This Folder ${basedir}" />
How can i use the macrodef for this condition which help in count all file with it
You can do this in many ways, including using plugins, such as ant-contrib, or using ant language extensions. But all of them are overkill compared to this simple build script:
<target name="count">
<countresources type="xml" />
<countresources type="java" />
<countresources type="cpp" />
</target>
<macrodef name="countresources">
<attribute name="type" />
<sequential>
<resourcecount property="#{type}.count">
<fileset dir="${basedir}">
<include name="*.#{type}" />
</fileset>
</resourcecount>
<echo message="There are ${#{type}.count} #{type} files in folder ${basedir}" />
</sequential>
</macrodef>
Hope this helps.
I need to iterate over all files in a directory. But I need just the name of each file, not absolute paths. Here's my attempt using ant-contrib:
<target name="store">
<for param="file">
<path>
<fileset dir="." includes="*.xqm"/>
</path>
<sequential>
<basename file="#{file}" property="name" />
<echo message="#{file}, ${name}"/>
</sequential>
</for>
</target>
The problem is that ${name} expression gets evaluated only once. Is there another approach to this problem?
From ant manual basename : "When this task executes, it will set the specified property to the value of the last path element of the specified file"
Properties once set are immutable in vanilla ant, so when using basename task within for loop, the property 'name' holds the value of the first file.
Therefore antcontrib var task with unset="true" has to be used :
<target name="store">
<for param="file">
<path>
<fileset dir="." includes="*.xqm"/>
</path>
<sequential>
<var name="name" unset="true"/>
<basename file="#{file}" property="name" />
<echo message="#{file}, ${name}"/>
</sequential>
</for>
</target>
Alternatively use local task, when using Ant 1.8.x or later :
<target name="store">
<for param="file">
<path>
<fileset dir="." includes="*.xqm"/>
</path>
<sequential>
<local name="name"/>
<basename file="#{file}" property="name" />
<echo message="#{file}, ${name}"/>
</sequential>
</for>
</target>
Finally you may use Ant Flaka instead of antcontrib :
<project xmlns:fl="antlib:it.haefelinger.flaka">
<fl:install-property-handler />
<fileset dir="." includes="*.xqm" id="foobar"/>
<!-- create real file objects and access their properties -->
<fl:for var="f" in="split('${toString:foobar}', ';')">
<echo>
#{ format('filename %s, last modified %tD, size %s bytes', f.tofile.toabs,f.tofile.mtime,f.tofile.size) }
</echo>
</fl:for>
<!-- simple echoing the basename -->
<fl:for var="f" in="split('${toString:foobar}', ';')">
<echo>#{f}</echo>
</fl:for>
</project>
If you're averse to using the var task due to Ant's standard of property immutability, there's a way to do this by taking advantage of the fact that normal property references ("${}")and iterated property references ("#{}") can be nested within one another:
<target name="store">
<for param="file">
<path>
<fileset dir="." includes="*.xqm"/>
</path>
<sequential>
<basename file="#{file}" property="#{file}" />
<echo message="#{file}, ${#{file}}"/>
</sequential>
</for>
</target>
This way, you'll be creating a new property named after each file name.
I have particular requirement. I have multiple reports file in particlar directly. Currently I build up ant script reading all files and checking for the particular string using the below code.
<target name="GenerateReports" >
<property name="search.string" value="Internal Error" />
<fileset id="existing" dir="${report.dir}">
<patternset id="files">
<include name="*.txt" />
</patternset>
</fileset>
<fileset id="matches" dir="${report.dir}">
<patternset refid="files" />
<contains text="${search.string}" />
</fileset>
<fail message="Found '${search.string}' in one or more test cases results in '${report.dir}' One or more test cases are failed">
<condition>
<resourcecount when="greater" count="0" refid="matches" />
</condition>
</fail>
</target>
But i want to read each file and give the name of the file where the error exists in my report file.
How to read the each file name and read the content also.
<foreach target="-List-File-Names" param="foreach.file" inheritall="true">
<path>
<fileset dir="${report.dir}" includes="*.txt">
<contains text="${search.string}" />
</fileset>
</path>
</foreach>
<target name="-List-File-Names">
<dirname property="file.dir" file="${foreach.file}"/>
<!-- dirname now holds the file -->
</target>
I have 2 different filesets defined in Ant as follows:
<fileset id="fileset1" dir="${classes.dir}">
</fileset>
<zipfileset id="fileset2" src="myArchive.zip" includes="**/*.class">
</zipfileset>
I want to create a third fileset which is the union of both the above filesets
<fileset id="merged">
</fileset>
Can someone tell me how to do this ? Is it even possible to do something like that ?
Thanks in advance!
One way to do this is with Ant resource collections, in particular a union.
<fileset id="fileset1" dir="${classes.dir}" />
<zipfileset id="fileset2" src="myArchive.zip" includes="**/*.class" />
<union id="onion">
<resources refid="fileset1" />
<resources refid="fileset2" />
</union>
Then you can refer to the 'onion' anywhere you might use a fileset, e.g.
<copy todir="dest">
<resources refid="onion" />
</copy>
I recommend using generic resources elements rather than filesets for maximum flexibility.
Try this: I think it should work, since <fileset> is an implicit <patternset>.
<fileset id="fileset1" dir="${classes.dir}">
</fileset>
<zipfileset id="fileset2" src="myArchive.zip" includes="**/*.class">
</zipfileset>
EDIT: odd. This perhaps?
<patternset id="merged">
<patternset refid="fileset1" />
<patternset refid="fileset2" />
</patternset>
problem with fileset is, that it requires a directory as a base upon it applies the patternset. Which means you have to find a common base directory that is shared by all filesets.
A <pathconvert> Task can take filesets via refid. You can put several filesets (e.g. from various build targets to assemble a compound set in a root/main target for a modular build environment):
<project name="root" basedir="." xmlns:if="ant:if" xmlns:unless="ant:unless">
<!--
it's important to take the xmlns:features in your project head
otherwhise this code won't work
-->
<target name="init">
<!-- set some common prerequisites -->
<property name="prerequisite.property.xyz" value="xyz" />
</target>
<target name="targetA" depends="init">
<fileset dir="${common.basedir}${file.separator}${targetA.subdir}" id="targetA.fileset">
<include name="**/*.html" />
</fileset>
<property name="targetA.fileset.exists" value="true" />
</target>
<target name="targetB" depends="init">
<fileset dir="${common.basedir}${file.separator}${targetB.subdir}" id="targetB.fileset">
<include name="**/*.java" />
</fileset>
<property name="targetB.fileset.exists" value="true" />
</target>
<target name="targetC" depends="init">
<fileset dir="${common.basedir}${file.separator}${targetC.subdir}" id="targetC.fileset">
<include name="**/*.class" />
</fileset>
<property name="targetC.fileset.exists" value="true" />
</target>
<target name="root" depends="init">
<pathconvert property="all.files.as.commaseparated.path" pathsep="," dirsep="/">
<fileset refid="targetA.fileset" if:true="${targetA.fileset.exists}" />
<fileset refid="targetB.fileset" if:true="${targetB.fileset.exists}" />
<fileset refid="targetC.fileset" if:true="${targetC.fileset.exists}" />
<map from="${common.basedir}/" to="" />
</pathconvert>
<!-- assemble new fileset from paths as comma separated property string -->
<fileset id="new.refid" dir="${common.basedir}" includes="${all.files.as.commaseparated.path}" />
</target>
</project>
This can be called via command line like:
ant targetA targetB targetC root
or
ant targetA root
Be aware that root is always the last target being called.
When using concat with fileset in Ant, how do I make an action happen for each element in the fileset. Such as, adding a string:
<fileset dir="${project.path.scripts-library}"
excludes="!*.js, **/*.bak, **/dev.*"
>
<type type="file" />
<include name="**/0*.js" />
<include name="**/1*.js" />
<string>test</string>
</fileset>
Or echoing the current file name for each file in the fileset (and, how do I GET the file name for the current file???):
<fileset dir="${project.path.scripts-library}"
excludes="!*.js, **/*.bak, **/dev.*"
>
<echo file="${app.path.file}"
append="true"
message=",${the.file.name}" />
<type type="file" />
<include name="**/0*.js" />
<include name="**/1*.js" />
</fileset>
I think there is no such thing in default ant. The closest one is <apply>, but it's system specific:
<apply executable="echo"> <!-- run this command with each file name -->
<fileset dir="/tmp" includes="**/*.*"/>
</apply>
Also you can install ant-contrib to enable <for> task:
<taskdef resource="net/sf/antcontrib/antcontrib.properties"/>
<for param="file">
<path>
<fileset dir="/tmp" includes="**/*.*"/>
</path>
<sequential> <!-- run any task here -->
<echo>file [#{file}]</echo>
</sequential>
</for>
