I'm trying to figure out a way to have Ant run a .jar executable that accepts a file and spits out several generated files from the single input file. Specifically, I'm trying to generate compiled .js files and at the same time generate .map files.
Normally, the command would look something like this:
java -jar compiler-latest --js a.js --js_output_file a.min.js --create_source_map a.js.map
Where:
compiler-latest is the closure-compiler jar
a.js is the JavaScript file to compile
a.min.js is the compiled JavaScript
a.js.map is the source map
My Ant script looks like this:
<project name="BuildTest" default="Build" basedir=".">
<description>
HTML Build Test with Ant
</description>
<property name="src" location="../js"/>
<property name="dst" location="../build"/>
<property name="compiler" location="../compiler.jar"/>
<!--Make Dest Directory-->
<target name="-destination">
<mkdir dir="${dst}"/>
</target>
<!--Compile JS-->
<target name="Build" depends="-destination">
<!--Filesets and Mappers-->
<fileset id="sourceFiles" dir="${src}" includes="*.js"/>
<mapper id="compiledJs" type="glob" from="*.js" to="*.compiled.js"/>
<mapper id="mapJs" type="glob" from="*.js" to="*.js.map"/>
<!--Apply Everything-->
<apply executable="java" parallel="false" dest="${dst}">
<!--Closure Compiler-->
<arg value="-jar"/>
<arg path="${compiler}"/>
<arg value="--compilation_level=SIMPLE_OPTIMIZATIONS"/>
<!--Source Files-->
<arg value="--js"/>
<srcfile/>
<fileset refid="sourceFiles"/>
<!--Output Files-->
<arg value="--js_output_file"/>
<targetfile/>
<mapper refid="compiledJs"/>
<!--Source Maps-->
<arg value="--source_map_format=V3"/>
<arg value="--create_source_map"/>
<arg value="--js_output_file"/>
<targetfile/>
<mapper refid="mapJs"/>
</apply>
</target>
<!--Clean Project-->
<target name="Clean" description="Cleans the project">
<delete dir="${dst}"/>
</target>
</project>
However, I get an error saying I can't have multiple <targetfile/> elements
apply doesn't support multiple targetfile elements.
This is a workaround, not nice, but effective.
You can use an Ant <compositemapper> to construct the command line for your application.
Below is an illustration. You need to set relative="yes" on the task in order that filenames relative to the build directory are used in preference to absolute filenames, otherwise mapping is harder. To build the command line provide a list of mappers inside the <compositemapper>. Use a <mergemapper> for fixed parts (args like --output_file), and use a suitable other mapper, maybe a glob, when you need to generate filenames.
A series of mappers is needed to separate the arguments passed to the java by <apply>, otherwise they will be passed as one long arg with embedded spaces.
<apply executable="java" parallel="false" relative="yes">
<arg line="-jar compiler-latest --js"/>
<srcfile />
<targetfile />
<compositemapper>
<mergemapper to="--js_output_file" />
<globmapper from="*.js" to="*.compiled.js" />
<mergemapper to="--source_map_format=V3" />
<mergemapper to="--create_source_map" />
<globmapper from="*" to="*.map" />
</compositemapper>
<fileset dir="." includes="*.js" />
</apply>
For a simple test that leads to a command line like:
java -jar compiler-latest --js 1.js --js_output_file 1.compiled.js --source_map_format=V3 --create_source_map 1.js.map
I am trying to automate BAR file creationI want to accept multiple values from user, store it in some list or array , then use all the variables in ANT script individually. Below is my script which I am trying :
<?xml version="1.0" encoding="UTF-8"?>

In above script, need to pass all resources which I accepted from user as arguments.
exec will not allow nested for loop.
So help me to pass all the values of resource as arguments to exec.
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 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>

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" />
<target name="compileLessCss" description="Compile the single less file to css">
<sequential>
<java jar="${tool.rhino}" fork="true">
<arg path="${tool.less}" />
<arg path="${single-input-lesscss-file}" />
<arg path="${single-output-css-file}" />
</java>
</sequential>
</target>
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.
