Build problem when including third party jars in classpath using ant

[ramya narayanan]

This is my build.xml file & it is in c:\sai folder.
My ant's bin folder is set in the path.

 
<project name="Asimplebuild"  basedir=".">
    <description>
        simple example build file
    </description>
  <!-- set global properties for this build -->
  <property name="src" location="C:\Sai\src"/>
  <property name="build" location="C:\buildoutput\classes"/>
 
  <property name="pdfsrc" location="C:\sai\pdfsrc"/>
  <property name="pdfbuild" location="C:\pdfbuild"/>
 [B]<property name="[B]classpath[/B]" value="C:\jdk1.5.0\lib;C:\Program Files\iTextjars\iText-2.1.4.jar;
C:\Program Files\iTextjars\iText-2.1.4-sources.jar;C:\Program Files\iTextjars\iText-rtf-2.1.4.jar;
C:\Program Files\iTextjars\iText-rups-2.1.4.jar" />[/B]
  
 
  
 
  <target name="compile" 
        description="compile the source " >
    <!-- Compile the java code from ${src} into ${build} -->
    <javac srcdir="${src}" destdir="${build}"/>
  </target>
 
<target name="[B]pdfcompile[/B]" description="compile the source">
<javac srcdir="${pdfsrc}"
       destdir="${pdfbuild}"
       classpath="${classpath}" />
  </target>
</project>
 

   

The major purpose of this build.xml is to check how to include third party jars using ant target & compile them using that.
But when I run the target pdfcompile , eventhough the build is successful it's the java file is not compiled & classes not created in output folder.

When I echo to check whether it is going into the target, it is now going to the target itself

 <target name="pdf" description="compile the source">
<echo message="Hello, world"/>
<javac srcdir="${pdfsrc}"
       destdir="${pdfbuild}"
       classpath="${classpath}" />
  </target>
</project>
   

But after properties when I give a echo message it is working properly.

 <property name="classpath" value="C:\jdk1.5.0\lib;C:\jdk1.5.0\bin;C:\Program Files\iTextjars\iText-2.1.4.jar;
C:\Program Files\iTextjars\iText-2.1.4-sources.jar;C:\Program Files\iTextjars\iText-rtf-2.1.4.jar;
C:\Program Files\iTextjars\iText-rups-2.1.4.jar" />
<echo message="Hello class path is set"/>
   

When i run ant

 
C:\sai>ant pdf
Buildfile: build.xml
     [B][echo] Hello class path is set
[/B]

Ok now with these modified build.xml file & putting my third party jars in E:\
TestAnt\lib .
I'm able to build successfully.
Consider my src directory is E\TestAnt

 
<project name="HelloMultipleWorld" basedir="." default="main">
    
 
    <property name="src.dir"     value="src"/>
 
    <property name="build.dir"   value="build"/>
    <property name="classes.dir" value="${build.dir}/classes"/>
    <property name="jar.dir"     value="${build.dir}/jar"/>
 
    [B]<property name="main-class"  value="HelloMultipleWorld"/>[/B]
     [B]<property name="lib.dir"     value="lib"/>[/B]
 
     [B]<path id="classpath">
        <fileset dir="${lib.dir}" includes="**/*.jar"/>
    </path>[/B]
 
    <target name="clean">
           <echo message="In clean "/>
        <delete dir="${build.dir}"/>
    </target>
 
    <target name="compile">
        <mkdir dir="${classes.dir}"/>
        <javac srcdir="${src.dir}" destdir="${classes.dir}" [B]classpathref="classpath"/>[/B]
    </target>
 
    <target name="jar" depends="compile">
        <mkdir dir="${jar.dir}"/>
        <jar destfile="${jar.dir}/${ant.project.name}.jar" basedir="${classes.dir}">
            <manifest>
                <attribute name="Main-Class" value="${main-class}"/>
            </manifest>
        </jar>
    </target>
 
    <target name="run" depends="jar">
        <java fork="true" [B]classname="${main-class}">[/B]
            <classpath>
                <path refid="classpath"/>
                <path location="${jar.dir}/${ant.project.name}.jar"/>
            </classpath>
        </java>
    </target>
 

    <target name="clean-build" depends="clean,jar"/>
 
    <target name="main" depends="clean,run"/>
 
</project>
 
   

Now when running

 
E:\TestAnt>ant
Buildfile: build.xml
 
clean:
     [echo] In clean
   [delete] Deleting directory E:\TestAnt\build
 
compile:
    [mkdir] Created dir: E:\TestAnt\build\classes
    [javac] Compiling 2 source files to E:\TestAnt\build\classes
 
jar:
    [mkdir] Created dir: E:\TestAnt\build\jar
      [jar] Building jar: E:\TestAnt\build\jar\HelloMultipleWorld.jar
 
run:
     [java] Hello World in PDF, RTF and HTML
 
main:
 
[B]BUILD SUCCESSFUL[/B]
