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.

<macrodef>
<if>
<then>
<exec executable="python" failonerror="true" outputproperty="result">
</exec>
</then>
<else>
<exec executable="python" failonerror="true" outputproperty="result">
</else>
</if> </macrodef>
I have a code block of macrodef which is called from a twice but when it is called second time the property "result" in the outputproperty is holding the old value and not getting replaced with the new value , I am new to ant would appreciate a work around this ..like if there is an alternative to use other than ant property
Using the https://ant.apache.org/manual/Tasks/local.html has solved the issue for me as the property defined with local is with in the scope of the tag.
Something like this
<sequential>
<local name="foo"/>
<property name="foo" value="bar.2"/>
<echo>Second sequential: foo is ${foo}</echo>
</sequential>
I have this ant script that is reading from a parameter a list of components and running other ant tasks (build.xml's):
<for list="${components.locations}" param="component" failonany="false">
<sequential>
<property name="#{component}" value="true"/>
<if>
<and>
<available file="${repository.location}/#{component}"/>
<available file="${repository.location}/${jars.location}"/>
</and>
<then>
<ant inheritAll="false" antfile="${repository.location}/#{component}/build.xml">
<!-- failonerror="false" -->
<property name="copy.libs" value="${copy.libs}"/>
<property name="repository.location" value="${repository.location}"/>
<property name="jars.location" value="${repository.location}/${jars.location}"/>
</ant>
</then>
</if>
</sequential>
</for>
The problem is if one component is failing, the script doesn't continue to next one.
I tried running with -k (-keep-going) argument but it doesn't help.
I found this property failonerror="false" but it's valid for "exec" tasks and couldn't integrate it with "ant" tasks or inside a "target".
Other direction was "failonany" property of the "for" but I didn't manage setting it up explicitly.
Can you please advice...
Thanks.
First of all, I would suggest deleting ant-contrib.jar and never looking back. Believe me, you will be doing yourself a favor.
You can use the subant task to iterate Ant builds on a set of directories or files. Simply define a dirset and pass any extra properties you need.
Instead of using ant-contrib's <if> block, use the standard target's if attribute to switch the entire target on or off. This is much safer and better practice.
<property name="repository.location" location="repository_location" />
<property name="jars.location" location="${repository.location}/jars" />
<property name="components" value="dir1,dir2,dir3" />
<target name="init">
<condition property="jars.available">
<available file="${jars.location}" />
</condition>
</target>
<target name="default" depends="init" if="jars.available">
<subant inheritall="false" failonerror="false">
<dirset id="components.dirs" dir="${repository.location}" includes="${components}" />
<property name="copy.libs" value="${copy.libs}" />
<property name="repository.location" value="${repository.location}" />
<property name="jars.location" value="${jars.location}" />
</subant>

I want do compile all *.less scripts in a specific folder and it subdirs with less-rhino-1.1.3.js.
There is an example on github for doing this for a specific file, which works perfect. But I want to do the same for a complete folder. I tried a lot, here is my last try.
It doesn't work, propertyregex seems not to be standard ANT, I don't want to use such things. I am not even sure if this code would work.
<project name="test" default="main" basedir="../../">
<property name="css.dir" location="public/css"/>
<property name="tool.less" location="bin/less/less-rhino-1.1.3.js"/>
<property name="tool.rhino" location="bin/tools/rhino/js.jar"/>
<macrodef name="lessjs">
<attribute name="input" />
<attribute name="output" />
<sequential>
<java jar="${tool.rhino}" fork="true" output="#{output}">
<arg path="${tool.less}"/>
<arg path="#{input}"/>
</java>
<echo>Lessjs: generated #{output}</echo>
</sequential>
</macrodef>
<target name="main">
<echo>compiling less css</echo>
<fileset dir="${css.dir}" id="myfile">
<filename name="**/*.less" />
</fileset>
<property name="lessfilename" refid="myfile"/>
<propertyregex property="cssfilename"
input="${lessfile}"
regexp="^(.*)\.less$"
replace="^\1\.css$"
casesensitive="true" />
<lessjs input="lessfile" output="cssfilename"/>
</target>
</project>
You could use the <fileset> to include all the less files need to be compiled. Later, you could use<mapper> to mark the corresponding detination css file.
<project name="test" default="main" basedir="../../">
<property name="css.dir" location="public/css"/>
<property name="tool.less" location="bin/less/less-rhino-1.1.3.js"/>
<property name="tool.rhino" location="bin/tools/rhino/js.jar"/>
<target name="less" description="Convert LESS to CSS then concatenate and Minify any stylesheets">
<echo message="Converting LESS to CSS..."/>
<!-- Clear the former compiled css files -->
<delete includeemptydirs="true">
<fileset dir="${css.dir}" includes="*.css, **/*.css" defaultexcludes="false"/>
</delete>
<apply dir="${css.dir}" executable="java" parallel="false" failonerror="true">
<!-- Give the input bundle of less files-->
<fileset dir="${css.dir}">
<include name="*.less"/>
</fileset>
<arg value="-jar" />
<arg path="${tool.rhino}" />
<arg path="${tool.less}" />
<srcfile/>
<!-- Output the compiled css file with corresponding name -->
<mapper type="glob" from="*.less" to="${css.dir}/*.css"/>
<targetfile/>
</apply>
</target>
</project>
I was able to piece together a working solution with the help of a couple of SO answers:
ANT script to compile all (css) LESS files in a dir and subdirs with RHINO
How to correctly execute lessc-rhino-1.6.3.js from command line
I had to download LESS 1.7.5 from GitHub and modify the Ant target to look like this. The -f argument and LESS JavaScript was key:
<property name="css.dir" value="WebContent/css"/>
<property name="less.dir" value="less"/>
<property name="tool.rhino.jar" value="test-lib/rhino-1.7R4.jar"/>
<property name="tool.rhino.lessc" value="test-lib/lessc-rhino-1.7.5.js"/>
<property name="tool.rhino.less" value="test-lib/less-rhino-1.7.5.js"/>
<target name="compile-less" description="compile css using LESS">
<apply dir="${css.dir}" executable="java" parallel="false" failonerror="true">
<fileset dir="${less.dir}">
<include name="styles.less"/>
</fileset>
<arg value="-jar"/>
<arg path="${tool.rhino.jar}"/>
<arg value="-f"/>
<arg path="${tool.rhino.less}"/>
<arg path="${tool.rhino.lessc}"/>
<srcfile/>
<mapper type="glob" from="*.less" to="${css.dir}/*.css"/>
<targetfile/>
</apply>
</target>
If anyone else is coming to this question recently, as I did, they may find that the less-rhino-1.1.3.js file given in the other answers does not work with the latest version of Rhino (which for me, as of now, is 1.7R4 from MDN). But the 1.4.0 version does, which can be obtained from Github here. So the relevant snippet from my build.xml, using these later versions, is shown. Note that I'm only compiling a single .less file to a single .css file, so no iteration or mappers are used (but obviously you can get those from the other answers). Other tweaks I made were to provide the output file as the final arg to less instead of capturing output from the Ant forked process, and to remove the dependency on ant-contrib stuff (not needed for the simple one-file case).
<property name="tool.rhino" value="build/lesscss/rhino1_7R4/js.jar" />
<property name="tool.less" value="build/lesscss/less-rhino-1.4.0.js" />
<property name="single-input-lesscss-file" value="/path/to/my/style.less" />
<property name="single-output-css-file" value="/output/my/style.css" />

<sequential>
<java jar="${tool.rhino}" fork="true">

If maven is an option for you, you could try wro4j-maven-plugin or wro4j-runner (which is a command line utility).
Using one of these, all you have do is to create an resource model descriptor (wro.xml):
<groups xmlns="http://www.isdc.ro/wro">
<group name="g1">
<css>/path/to/*.less</css>
</group>
</groups>
The rest will be handled by the wro4j library. No need to carry about how rhino works or other details.
Disclaimer: I'm working on wro4j project
I had the same issue. I developed a solution using ant-contrib. It expects all of your .less files to be in one flat directory and to be moved to another flat directory. It will change the file extension to .css in the process.

I was unable to get this to run using a JDK 1.6 since the javascript stuff has been incorporated to the JDK. The JDK does have a jrunscript executable in the distribution but when I try to run the less-rhino.js file it fails to recognize any readFile() function. Has anyone looked into that. Otherwise I may be giving the lesscss-engine a shot and enhancing it to understand filesets.
The following is my ant script:
<project name="nightly_build" default="main" basedir="C:\Work\6.70_Extensions\NightlyBuild">
<target name="init">
<sequential>
<exec executable="C:/Work/Searchlatestversion.exe">
<arg line='"/SASE Lab Tools" "6.70_Extensions/6.70.102/ANT_SASE_RELEASE_"'/>
</exec>
<property file="C:/Work/latestbuild.properties"/>
<sleep seconds="10"/>
<echo message="The product version is ${Product_Version}"/>
<exec executable="C:/Work/checksnapshot.exe">
<arg line='"ANT_SASE_RELEASE_${Product_Version}_SASE Lab Tools-NightlyBuild" ANT_SASE_RELEASE_${Product_Version}_AnalyzerCommon-NightlyBuild ${Product_Version}-AppsMerge' />
</exec>
<property file="C:/Work/checksnapshot.properties"/>
<tstamp>
<format property="suffix" pattern="ddMMyyyyHHmm"/>
</tstamp>
</sequential>
</target>
<target name="main" depends="init">
<echo message="loading properties files.." />
<sleep seconds="10"/>
<echo message="Backing up folder" />
<move file="C:\NightlyBuild\NightlyBuild" tofile="C:\NightlyBuild\NightlyBuild.${suffix}" failonerror="false" />
<parallel>
<exec executable="C:/Work/sortfolder.exe">
<arg line="6" />
</exec>
<exec executable="C:/Work/6.70_Extensions/NightlyBuild/antc.bat">
</exec>
</parallel>
</target>
</project>
Basically the sequence goes something like this:
I will run Searchlatestversion.exe and write latestbuild.properties
Using the latestbuild.properties i will obtain ${Product_Version} and would like to allow checksnapshot.exe access to latestbuild.properties and obtain ${Product_Version}
checksnapshot.exe will then generate checksnapshot.properties which will then be used by the target in main antc.bat
am i doing something wrong over here? seems like ${Product_Version} is not being received well by checksnapshot.exe
You appear to have a hard coded wait period of 10 seconds for Searchlatestversion to write out your file. If the executable does not complete inside that time, ${Product_Version} cannot be read from file.
Have you considered using the Waitfor Ant Task? As the name implies, this will wait for a certain condition before it will allow the rest of the task to progress. You could do something like
<property name="props.file" value="C:/Work/latestbuild.properties"/>
<waitfor maxwait="10" maxwaitunit="second">
<available file="${props.file}"/>
</waitfor>
<property file="${props.file}"/>
Does Searchlatestversion.exe produce the file C:/Work/latestbuild.properties?
If so, should you not sleep/wait before you load that properties file?
You have this:
<exec .../>
<property file="C:/Work/latestbuild.properties"/>
<sleep seconds="10"/>
Should you not have this:
<exec ... />
<sleep seconds="10"/>
<property file="C:/Work/latestbuild.properties"/>
I am attempting to remove all lines that begin with log if a macrodef attribute is set to prod (example below). I plan on using replaceregexp to remove all lines beginning with log. However, I am not sure how to test if an attribute is set to a specific value, besides using the if task. I would like to not introduce any non-core Ant tasks to perform this, but I can't come up with any other solutions. Do I have any other options besides using the if-task?
Thanks
<macrodef name="setBuildstamp">
<attribute name="platform" />
<sequential>
<if>
<equals arg1="platform" arg2="prod" />
<then>
<replaceregexp match="^log\(.*" value="" />
</then>
</if>
</sequential>
</macrodef>
You should use a reference to a parameter, like this #{platform}.
Also, your replaceregexp task is missing a few parameters.
I think that in your particular case it is better to use linecontainsregexp filter reader. Here is modified code (note negate argument to linecontainsregexp).
<macrodef name="setBuildstamp">
<attribute name="platform" />
<sequential>
<if>
<equals arg1="#{platform}" arg2="prod" />
<then>
<copy todir="dest-dir">
<fileset dir="src-dir"/>
<filterchain>
<linecontainsregexp
regexp="^log\(.*"
negate="true"
/>
</filterchain>
</copy>
</then>
</if>
</sequential>
</macrodef>
They may be a couple of ways to solve this, but none are as straightforward as using the ant-contrib element. I'm not sure if this will get you what you need for your application, but you could try the following:
Using conditional targets. If you can replace your macrodef with a target to call, this may work for you. Note that this will set the property globally, so it might not work for your application.
<target name="default">
<condition property="platformIsProd">
<equals arg1="${platform}" arg2="prod" />
</condition>
<antcall target="do-buildstamp" />
</target>
<target name="do-buildstamp" if="platformIsProd">
<echo>doing prod stuff...</echo>
</target>
Handle the 'else' case. If you need to handle an alternate case, you'll need to provide a few targets...
<target name="default">
<property name="platform" value="prod" />
<antcall target="do-buildstamp" />
</target>
<target name="do-buildstamp">
<condition property="platformIsProd">
<equals arg1="${platform}" arg2="prod" />
</condition>
<antcall target="do-buildstamp-prod" />
<antcall target="do-buildstamp-other" />
</target>
<target name="do-buildstamp-prod" if="platformIsProd">
<echo>doing internal prod stuff...</echo>
</target>
<target name="do-buildstamp-other" unless="platformIsProd">
<echo>doing internal non-prod stuff...</echo>
</target>
Using an external build file. If you need to make multiple calls with different values for your property, you could isolate this in another build file within the same project. This creates a bit of a performance hit, but you would not need the additional library.
in build.xml:
<target name="default">
<ant antfile="buildstamp.xml" target="do-buildstamp" />
<ant antfile="buildstamp.xml" target="do-buildstamp">
<property name="platform" value="prod" />
</ant>
<ant antfile="buildstamp.xml" target="do-buildstamp">
<property name="platform" value="nonprod" />
</ant>
</target>
in buildstamp.xml:
<condition property="platformIsProd">
<equals arg1="${platform}" arg2="prod" />
</condition>
<target name="do-buildstamp">
<antcall target="do-buildstamp-prod" />
<antcall target="do-buildstamp-other" />
</target>
<target name="do-buildstamp-prod" if="platformIsProd">
<echo>doing external prod stuff...</echo>
</target>
<target name="do-buildstamp-other" unless="platformIsProd">
<echo>doing external non-prod stuff...</echo>
</target>
Add ant-contrib to your project. Of course, if you can add a file to your project, the easiest thing would be to just add the ant-contrib.jar file. You could put it under a "tools" folder and pull it in using a taskdef:
<taskdef resource="net/sf/antcontrib/antlib.xml" classpath="${basedir}/tools/ant-contrib.jar" />
It looks like when you are building your project specifically for your Production environment - you are stripping out code you don't want to run in Production. Thus you are creating a different binary than what will run in your Dev or Testing environment.
How about using an environment variable or property file at run-time instead of build-time which determines whether or not logging happens? This way when you're having trouble in Production and you want to use the same exact binary (instead of determining the revision, checking out the code, rebuilding with a different environment flag) you just re-deploy it to your Dev or Test environment and turn on debugging in a properties file or environment variable?
