Using Ant to build dependencies of the current build target

Say I have a library and a binary target, let's call them MyLib and MyBin,
MyBin depends on MyLib.
I'm trying to create an Ant buildfile for MyBin that first builds MyLib and then includes it in the classpath when building MyBin.
I've tried using Ant tasks as in Building other, dependent projects with Ant .
However, it's not working, and from ant -v I think the MyBin build-deps target is not even building MyLib. Seems like it's confusing MyBin and MyLib properties? I'm not sure how to prevent this though.
I'm dumping only MyBin/build.xml below, but the MyLib is almost identical, except it does not have the build-deps target.
<project name="MyBin" default="main" basedir=".">
<property name="projectName" value="MyBin" />
<property name="src.dir" location="src" />
<property name="build.dir" location="bin" />
<property name="dist.dir" location="dist" />
<property name="dist.lib.dir" location="dist/lib" />
<property name="lib.dir" value="lib" />
<target name="build-deps" depends="init">
<!-- MyLib main target does clean -> build -> jar to dist folder -->
<!-- Its build.xml uses many of the same property values as above -->
<ant antfile="../MyLib/build.xml" target="main"/>
</target>
<path id="classpath">
<fileset dir="${basedir}/">
<include name="../MyLib/dist/**/*.jar" />
</fileset>
</path>
<!-- Need classpath to run this -->
<target name="compile" depends="build-deps" description="compile the source ">
<javac includeantruntime="false" srcdir="${src.dir}"
destdir="${build.dir}" classpathref="classpath" />
</target>
<!-- Group all dependencies into a big dependency-all.jar -->
<target name="copy-dependencies">
<mkdir dir="${dist.lib.dir}" />
<jar jarfile="${dist.lib.dir}/dependencies-all.jar">
<zipgroupfileset dir="${lib.dir}">
<include name="**/*.jar" />
</zipgroupfileset>
</jar>
</target>
<!-- jar it, extract above dependency-all.jar and zip it with project files -->
<target name="jar" depends="compile, copy-dependencies"
description="package, output to JAR">
<mkdir dir="${dist.dir}" />
<mkdir dir="${dist.lib.dir}" />
<jar jarfile="${dist.dir}/${projectName}.jar" basedir="${build.dir}">
<manifest>
<attribute name="Main-Class" value="${main-class}" />
</manifest>
<zipfileset src="${dist.lib.dir}/dependencies-all.jar"
excludes="META-INF/*.SF" />
</jar>
</target>
<target name="clean" description="clean up">
<delete dir="${build.dir}" />
<delete dir="${dist.dir}" />
</target>
<!-- Default, run this -->
<target name="main" depends="clean, compile, jar" />
</project>
What I see with ant -v in MyBin is something along the lines of:
build-deps:
Project base dir set to: /MyBin
[ant] calling target(s) [main] in build file /MyLib/build.xml
parsing buildfile /MyLib/build.xml with URI = file:/MyLib/build.xml
Project base dir set to: /MyBin
Override ignored for property "projectName"
Override ignored for property "build.dir"
Override ignored for property "dist.dir"
Override ignored for property "dist.lib.dir"
Override ignored for property "lib.dir"
[pathconvert] Set property classpath.name =
[ant] Entering /MyLib/build.xml...
Build sequence for target(s) `main' is [clean, init, copy-dependencies, jar, main]
Complete build sequence is [clean, init, copy-dependencies, jar, main, ]
clean:
[delete] Deleting directory /MyBin/bin
[delete] Deleting directory /MyBin/bin
init:
[mkdir] Created dir: /MyBin/bin
copy-dependencies:
[ant] Exiting /MyLib/build.xml.

On your specific question:
seems like it's confusing MyBin and MyLib properties? I'm not sure how
to prevent this though.
You are using this to invoke the MyLib build:
<ant antfile="../MyLib/build.xml" target="main" />
A build invoked via the <ant> task this way by default inherits all properties from the caller, including basedir, hence the build is run in the wrong place.
Instead you could use, for example:
<ant dir="../MyLib" />
That will run build.xml in the specified directory, set the basedir property, and call the default target, which should be main if you are using a very similar buildfile for the library as you say. If you don't want to inherit properties from MyBin when executing the MyLib task, specify inheritAll=false in the task.
From the <ant> task docs for the dir attribute:
the directory to use as a basedir for the new Ant project (unless
useNativeBasedir is set to true). Defaults to the current project's
basedir, unless inheritall has been set to false, in which case it
doesn't have a default value. This will override the basedir setting
of the called project. Also serves as the directory to resolve the
antfile and output attribute's values (if any).

include maven-ant build libs in eclipse java project

I am struggling with maven-ant build with eclipse.
I did work like below steps.
[GUI] new java project
add build.xml in project top folder
run ant file and SUCCEED!
trying to code, but somehow auto completion does not work.(guessing eclipse can not read maven-ant dependency.path)
So I tried.
add ~/.m2/repository in build path as a External class folder - does not work - It looks weird to me to include whole this folder. My current project, I need little libraries, but it has whole libraries that I uses in other projects.
add builders with build.xml like Want an eclipse java project to run ant build files automatically - does not work neither.
How can I add this maven-ant libraries properly? Thanks for sharing your experiences and answers XD

Thanks again b

For what you are trying to do, you need the filesetId and versionsId="dependency.versions" in your declaration of:
<artifact:dependencies filesetId="dependency.fileset" versionsId="dependency.versions"
Then add a copy task like so:
<copy todir="${lib.dir}">
<fileset refid="dependency.fileset" />
<mapper classpathref="maven-ant-tasks.classpath"
classname="org.apache.maven.artifact.ant.VersionMapper"
from="${dependency.versions}" to="flatten" />
</copy>
The to="flatten" will flaten your dependencies into a single folder, then you can include that folder on the classpath of eclipse project or wherever you need it.

I'm trying to utilizing SASS in an ant file while removing ruby dependencies

I am currently using a ruby gem SASS in order to convert my *.scss files to *.css files on a large project. Here is a mockup of the code I am using:
<?xml version="1.0"?>
<!-- scss to CSS -->
<project name="StackOverflowScssCss" default="sass-compile-to-css" basedir=".">
<property file="build.properties" />
<target name="sass-compile-to-css">
<echo message="Compiling scss files to css..." />
<!-- create the css destination dir if it doesn't already exist -->
<property name="css-dest" location="${css.dir}" />
<echo message="Creating directory at ${css.dir} [if it doesn't yet exist]" />
<mkdir dir="${css-dest}" />
<!-- create subdirs if necessary -->
<echo message="Creating css directories (and temporary .css files) for .scss to be compiled..." />
<touch mkdirs="true">
<fileset dir="${sass.dir}" includes="**/*.scss" excludes="**/_*" />
<mapper type="glob" from="*.scss" to="${css.dir}/*.css" />
</touch>
<echo message="Running sass executable against sass files and compiling to CSS directory [${css-dest}] " />
<!-- run sass executable -->
<apply executable="sass" dest="${css-dest}" verbose="true" force="true" failonerror="true">
<arg value="--unix-newlines" />
<!-- Disable creation of map file. THIS SHOULD BE A FLAG -->
<arg value="--sourcemap=none" />
<srcfile />
<targetfile />
<fileset dir="${sass.dir}" includes="**/*.scss" excludes="**/_*" />
<mapper type="glob" from="*.scss" to="*.css" />
</apply>
<echo message="Done compiling scss files!" />
</target>
</project>
Ultimately I want to remove the ruby dependency so I have been looking at this libsass maven plugin. I know that there are many options for libsass but I am trying to stick strictly to Java. Does anyone have any experience with doing this? I don't want to run Node.js, Sass.js ot anything, and I have racked my brain all day on how to do this. Any help is much appreciated!

There is a Java wrapper that can be used with Maven.
If you really want to stick with Java you could either
Use that wrapper and run the mvn task from inside your ant script (see here)
Adapt that wrapper and build your own Ant Task out of it

I ended up using a JRuby dependency in order to run on the JVM. My code is as follows:
<!-- Jruby Dependent SCSS to CSS conversion -->
<path id="JRuby">
<fileset file="packages/jruby-complete-1.7.20.1.jar"/> <!-- Location of JRuby jar file -->
</path>
<target name="compileSass" depends="cleanSass">
<echo message="Compiling scss files..." />
<!-- JRuby Script to convert files into new directory -->
<property name="filesIn" value="${dir.scss}/**/[^_]*.scss" />
<property name="projectDirectory" value="${user.dir}"/>
<script language="ruby" classpathref="JRuby">
<![CDATA[

files.each do

newOutDir = File.dirname(file).sub! 'scss', 'css'

puts "[sass compiler] From:" + file

opts.parse
end
]]>
</script>

Jenkins compile problems

this question is quite silly, but I can't find anyone else in the internet it seems who got the same problem and can't fix it themself.
This is my build.xml
I took it from an forum and changed the lines I knew what to put in.

Ant Nested Update

This is a follow up question related to my question from yesterday:
Ant Ear Update Without Full Exploding Ear
I'm using Ant 1.8.2 and am able to update files in an ear, using the example I made in the provided link above.
I have a war file inside my ear file, and I'm hoping to see if there is a way to do a nested update (e.g. update a file in the war that is in the ear).
My other option is to extract the war, update the war, then update the ear with the updated war. If there is a way to do the nested update, I think it would save me time, as my war file is pretty big.

The following is my alternative approach POC, in case anyone is interested. I will use this if we cannot find a "nested" update.
<property name="ear.file1" value="file1.ear"/>
<property name="war.file1" value="war1.war"/>
<property name="war.file" value="war.war"/>
<property name="war.file.backup" value="warBk.war"/>
<property name="text.file1" value="1.txt"/>
<property name="text.file2" value="2.txt"/>
<property name="xml.application1" value="application.xml"/>
<target name="clean">
<delete file="${ear.file1}"/>
<delete file="${war.file}"/>
<delete file="${war.file.backup}"/>
</target>
<target name="run">
<!-- Our war file contains 1.txt, allows us add 2.txt and verify updates properly -->
<copy file="${war.file1}" tofile="${war.file}"/>
<!-- simple ear that will be updated -->
<ear earfile="${ear.file1}" appxml="${xml.application1}">
<fileset dir="." includes="${text.file1}"/>
<fileset dir="." includes="${war.file}"/>
</ear>
<!-- Backup war, for comparision purposes -->
<move file="${war.file}" tofile="${war.file.backup}" overwrite="true" />
<!-- Extact the war we just added -->
<unzip dest="." src="${ear.file1}" overwrite="true" >
<patternset>
<include name="${war.file}" />
</patternset>
</unzip>
<!-- Update the war by adding a file -->
<war destfile="${war.file}" update="true">
<fileset dir="." includes="${text.file2}"/>
</war>
<!-- Update the ear with our updated war -->
<ear earfile="${ear.file1}" appxml="${xml.application1}" update="true">
<fileset dir="." includes="${war.file}"/>
</ear>
</target>
<target name="main" depends="clean,run"/>
