Let's say I have checkedout a folder inside the folder BuildI12 and I want to update it using the ant, how can I do that.?
I don't how to create customized tasks in ant.
If i Understand your needs and you mean run a SVN UPDATE from a custom ant task, you can do something like this:
<target name="svn_command" description = "run svn update command">
<if> <os family="windows"/>
<then>
<exec dir="." executable="cmd.exe" outputproperty="svnlog.out" failonerror="true" >
<arg line="/c svn update"/>
</exec>
</then>
<else>
<exec executable="svn" outputproperty="svnlog.out">
<arg line=" update"/>
</exec>
</else>
</if>
</target>
Obviously you can do more trick, using placeholder and creating dynamic task that could work for different SVN operations..
Let me know if this fits your needs..

I have a got a ANT build system which invokes builds on different projects using following macro;
<macrodef name="buildComponent">
<attribute name="name"/>
<attribute name="dir"/>
<attribute name="antTarget"/>
<attribute name="antCommonDistDir" />
<sequential>
<available property="build.xml.exists.#{dir}" file="#{dir}/build.xml" />
<if>
<equals arg1="${build.xml.exists.#{dir}}" arg2="true" />
<then>
<java classname="org.apache.tools.ant.launch.Launcher"
fork="true"
failonerror="true"
dir="#{dir}"
timeout="4000000"
output="${common.build.dir}/log/#{name}.log"
taskname="startAnt" >
<jvmarg value="-Dant.home=${ant.home}"/>
<classpath>
<pathelement location="${ant.home}/lib/ant-launcher.jar"/>
</classpath>
<arg value="-Dbasedir=#{dir}"/>
<arg value="#{antTarget}"/>
<arg value="-Dprop1=${prop1}" />
<syspropertyset refid="project.common.properties" />
<sysproperty key="common.dist.dir.os" value="#{antCommonDistDir}" />
</java>
</then>
</if>
</sequential>
</macrodef>
I would like to override properties form command line but the problem is that these properties are not being passed by task and my subsequent build uses the default values. For example I am executing the build as follows;
ant dist -Dprop1=override.prop1 -Dprop2=override.prop2 -Dprop3=override.prop3
As you see currently the only option for me to pass these overridden values from command line for prop2 and prop3 is add <arg /> under <java /> task for each property passed like I have done for 'prop1' which works but not desirable. Is there anyway I can access all properties passed to ANT and simply pass them as is to <java /> task?
You can use the echoproperties task to save all current Ant properties to a file, and then pass that file to the java task to be loaded by the subproject.
<echoproperties destfile="my.properties"/>
Having said this, a better solution instead of executing the java command to invoke another Ant build, you can simply call the ant task which will build your subproject and automatically inherit all properties from the parent project:
<available property="build.xml.exists.#{dir}" file="#{dir}/build.xml" />
<if>
<equals arg1="${build.xml.exists.#{dir}}" arg2="true" />
<then>
<ant antfile="#{dir}/build.xml" target="#{antTarget}"/>
</then>
</if>
I couldn't find any thing which can do this directly. So I ended up writing a javascript and populated a ant property to parse command line options which was stored in env variable and passed it to <java /> task as <arg line="${command.line.properties}" />. Remember to use <arg line="" /> as it trim out all extra spaces etc before invoking a task.
I am attempting to use an Ant build script to build a project that already has nmake (Visual Studio) build scripts. Rather than redo the entire build script, I would like to have Ant reuse the existing scripts.
So, I have something like this which works for Windows Mobile 6 ARMV4I builds:
<project ...>
<target name="-BUILD.XML-COMPILE" depends="-init, -pre-compile">
<exec executable="cmd">
<arg value="/c"/>
<arg line='"${g.path.project}\build-wm6-armv4i.bat"'/>
</exec>
<antcall target="-post-compile" inheritall="true" inheritrefs="true" />
</target>
</project>
But I would also like it to work for other platforms like Win32 x86 and Windows CE6 x86.
How can I have the Ant script discriminate which batch file it should execute to perform the build?
The <os> condition may be used to set properties based on the operating system and the hardware architecture. Targets may be conditionally executed using the if and unless attributes.
<?xml version="1.0" encoding="UTF-8"?>
<project name="build" basedir="." default="BUILD.XML-COMPILE">
<condition property="Win32-x86">
<and>
<os family="windows" />
<or>
<os arch="i386" />
<os arch="x86" />
</or>
</and>
</condition>
<condition property="Win-ARMv4">
<os family="windows" arch="armv4" />
</condition>
<target name="-BUILD.XML-COMPILE_Win-ARMv4" if="Win-ARMv4"
depends="-init, -pre-compile">
<exec executable="cmd">
<arg value="/c"/>
<arg line='"${g.path.project}\build-wm6-armv4i.bat"'/>
</exec>
<antcall target="-post-compile" inheritall="true" inheritrefs="true" />
</target>
<target name="-BUILD.XML-COMPILE_Win32-x86" if="Win32-x86"
depends="-init, -pre-compile">
<exec executable="cmd">
<arg value="/c"/>
<arg line='"${g.path.project}\build-win32-x86.bat"'/>
</exec>
<antcall target="-post-compile" inheritall="true" inheritrefs="true" />
</target>
<!-- Execute the correct target automatically based on current platform. -->
<target name="BUILD.XML-COMPILE"
depends="-BUILD.XML-COMPILE_Win-ARMv4,
-BUILD.XML-COMPILE_Win32-x86" />
</project>
The paths to the batch files are both single and double quoted so that file paths with spaces will not break the script. I have not tested this script on Windows Mobile 6 ARMV4I, so you will want to use the Ant target below to verify the name.
<target name="echo-os-name-arch-version">
<echo message="OS Name is: ${os.name}" />
<echo message="OS Architecture is: ${os.arch}" />
<echo message="OS Version is: ${os.version}" />
</target>

I want to use resolvers (ssh) which are dependant on ant classpath.
Something like

To use it I need jsch in ant classpath. Ant script should depends only on common lib (which also includes resolved jsch dependencies) - to use it on any client PC. Scenario is:
task to download lib.

But ivy:configure does not have any classpathref param, so it is unclear for me how to load jars I extracted.
Is it possible?
Or, probably, somehow run ant again internally with extended classpath?

I have gone through number of posts on the very forum but couldn't sort it out. I am trying to run a BAT file from ANT script. The folder hierarchy is like this
- Project
| - build.xml
| - build-C
| | - test.bat
The ANT file that i wrote so for is
<project name="MyProject" basedir=".">
<property name="buildC" value="${basedire}\build-C" />
<exec dir="${buildC}" executable="cmd" os="Windows XP">
<arg line="/c test.bat"/>
</exec>
</project>
The bat file content is
echo In Build-C Test.bat
It says that build failed .. :s i dun know what wrong am i doing ?
<property name="buildC" value="${basedire}\build-C" />
This should be ${basedir} I guess? Use
<echo>${buildC}</echo>
to make sure the dir is correct.
And shouldn't
<exec dir="${buildC}" executable="test.bat" os="Windows XP" />
do the job?
Hopefully this will help expand on the already given/accepted answers:
I suggest executing cmd with the batch script as a parameter:
<exec failonerror="true" executable="cmd" dir="${buildC}">
<arg line="/c "${buildC}/test.bat""/>
</exec>
Not sure if it is necessary to use the absolute path "${buildC}/test.bat" since dir is specified, but I put it just in case. It might be enough to use /c test.bat.
My project executes a batch script on Windows operating systems & a shell script on all others. Here is an example:
<target name="foo">
<!-- properties for Windows OSes -->
<condition property="script.exec" value="cmd">
<os family="windows"/>
</condition>
<condition property="script.param" value="/c "${basedir}/foo.bat"">
<os family="windows"/>
</condition>
<!-- properties for non-Windows OSes -->
<property name="script.exec" value="sh"/>
<property name="script.param" value=""${basedir}/foo.sh""/>
<echo message="Executing command: ${script.exec} ${script.param}"/>
<exec failonerror="true" executable="${script.exec}" dir="${basedir}">
<arg line="${script.param}"/>
</exec>
</target>
I'd like to execute subant on some condition. something like:
<if>
<equals value="value1" property="${some.property">
<then>
<subant target="#{target}" failonerror="true" inheritall="false">
<buildpath refid="some-ref1" />
</subant>
</then>
<else>
<subant target="#{target}" failonerror="true" inheritall="false">
<buildpath refid="some-ref2" />
</subant>
</else>
</if>
But can't find a way to do it. Read the ant manual and googled, but no solution is found.
Thanks.
I believe the error may lie in your equals tag. Instead of using the 'value' and 'propery' attributes, try using 'arg1' and 'arg2', i.e.:
<equals arg1="value1" arg2="${some.property}">
Check out the examples in the ant-contrib doc: http://ant-contrib.sourceforge.net/tasks/tasks/if.html.
If the problem is that your 'if', 'then', and/or 'else' tags are not resolving properly, then you may be missing the ant-contrib libraries. Ant-contrib is not natively included with ant, but you can download it here: http://sourceforge.net/projects/ant-contrib/files/
Per the ant-contrib site (http://ant-contrib.sourceforge.net/), here's what you must do to install ant-contrib:
Option 1: Copy ant-contrib-0.3.jar to the lib directory of your Ant installation. If you want to use one of the tasks in your own project, add the lines
<taskdef resource="net/sf/antcontrib/antcontrib.properties"/>
to your build file.
Option 2: Keep ant-contrib-0.3.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/antcontrib.properties">
<classpath>
<pathelement location="/usr/share/java/lib/ant-contrib-0.3.jar"/>
</classpath>
</taskdef>
Please look up a <target if="${some.property}>. You may want another target with an unless.
If the property has to do with a file existing, see Ant task to check a file exists?. Even if this is not your main concern, I am sure you can get the idea from the accepted answer.
Do you mean calling another target
if so here is
<if>
<equals value="value1" property="${some.property">
<then>
<antcall target="#{target}" failonerror="true" inheritall="false">
</then>
<else>
<antcall target="#{target}" failonerror="true" inheritall="false">
</else>
</if>
