Ant Build Failing -- Need a way to pick jar file during run time.

[Prachi Garg]

Hi Everyone, I am new to ANT. I am looking for some inputs on writing build.xml file, I have written one, It works fine if I include one of my jar file in ../WEB-INF/lib folder.

I dont want this jar file to be packaged while creating WAR/EAR files and This jar file is required during run time and want to exclude this jar file from ../WEB-INF/lib folder and still build successfully..

Please let me know possible solutions.

My Build.xml file looks like:

<?xml version="1.0" encoding="UTF-8"?>

<!-- ***************************************************************************************************** 

	This is a sample build file. Execute this as 
	ant -f sample_build.xml
	
	***************************************************************************************************** -->


<project name="sample" default="sample.build" basedir=".">
	<!-- You can include build.properties if you want to include the environment specific details 
	<property file="build.properties"/> -->
	<buildnumber file="./sample.counter"/>
	
	<property name="deploy.dir" value="${basedir}/deploy"/>
	<property name="build.dir" value="${basedir}/build"/>
	<property name="classes.dir" value="${build.dir}/classes"/>
	
	<!-- Display useful message to screen -->
	<echo message="Building in ${basedir} using Java ${java.version}."/>
	<echo message="The identifier for this build is ${buildLabel}"/>
	<echo message="Build system is ${os.name} ${os.version} running on ${os.arch}"/>
	
	<target name="pathset">
		
		<!-- =============== Class path for project =============== -->
		<path id="sample.classpath">
        	
			<pathelement location="${classes.dir}/Pipelink_Core/"/>
			<fileset dir="../Somepath/lib">
							<include name="**/*.jar"/>
				<!--
				Here you need to set path for the JAR containing following class
				1) package org.apache.commons.logging
				2) org.netlib.blas 
				and if any more references
				-->
			</fileset>
			
		</path>
		
</target>

		
	<!-- Clean build working directories --> 
	<target name="clean">
			<echo message="Starting execution of target clean..."/>
			<delete dir="${build.dir}"/>
	</target>
	
	<!-- Create build working directories -->
	<target name="init" depends="clean">
			<echo message="Starting execution of target init..."/>
			<mkdir dir="${classes.dir}"/>
			<mkdir dir="${deploy.dir}"/>
	</target>

	<!-- Build sample -->
	<target name="sample.build" depends="clean,init,pathset">
		<echo message="Starting execution of target sample.build ..."/>
		<javac debug="true" nowarn="on" destDir="${classes.dir}">
			<src path="./Src"/>
			<classpath refid="sample.classpath"/>
		</javac>
	</target>
	
	<!-- Create WAR file given as sample, you need to tweak it-->
    <target name="sample_war.build" description="Build Web archive">
    		<echo message="Starting execution of target sample_war.build ..."/>
   			<!-- Copy WebContent files except precompiled-classes folder form Workspace excluding WEB-INF folder  -->
			<copy includeemptydirs="false" todir="${classes.dir}/SkedExUI_webapp/">
				<fileset dir="./ViewController/public_html" excludes="**/WEB-INF/**,**/*.bak ,**/*.log,**/*.java,**/*.copyarea.db,**/*Thumbs.db,**/*.svn"/>
			</copy>
    		
    		<!-- Now create WAR file -->
    		<war destfile="./build/classes/SkedExUI_ViewController_webapp1.war" webxml="./ViewController/public_html/WEB-INF">
				<fileset dir="${classes.dir}/SkedExUI_webapp"/>
			</war>
    </target> 
	
</project>

Welcome to the Ranch, Prachi!

Any Suggestions here please?

The copy statement in lines 72-74, try adding an excludes value to not copy the JAR file you don't want. In general, that is how you prevent Ant from copying files you don't want.

If I know exactly what the JAR file was named, and where it is located, I could be more specific. Posting the project directory and file structure would help.
