Ant - how to get all files' name in a specific folder

Question

Here is my Ant script for generating jar package. I have bunch of jar packages for manifest Class-Path attribute, they are all in an specific folder. I don't want to hard code it, how can I get them automatically?

          <jar jarfile="${client_deploy_dir}/HelloWorld.jar" basedir="${client_work_dir}/compiled">
              <manifest>
                 <attribute name="Main-Class" value="HelloWorld.Main"/>
                 <attribute name="Class-Path" value="???"/>
              </manifest>
           </jar>

Answer 1

Check out the ant pathconvert task. You can use this to expand an existing fileset into a list of files.

Answer 2

You're on the right track, use manifestclasspath task. The jarfile attribute is used to create relative links to the jars contained in the fileset.

<manifestclasspath property="jar.classpath" jarfile="${client_work_dir}/HelloWorld.jar">
    <fileset name="" dir="${client_work_dir}/lib" >
        <include name="*.jar"/>
    </fileset>
</manifestclasspath>

<jar jarfile="${client_deploy_dir}/HelloWorld.jar" basedir="${client_work_dir}/compiled">
    <manifest>
         <attribute name="Main-Class" value="HelloWorld.Main"/>
         <attribute name="Class-Path" value=""${jar.classpath}"/>
      </manifest>
   </jar>

Answer 3

Now, the problem I have is the wrong format in MANIFEST.MF:

Here is Class-Path in my MANIFEST.MF

---

 Class-Path: lib/DirtyListener.jar
   lib/Recurring.jar

   lib/RowSet.jar
   lib/activation.jar
   lib/bfor
  eport.jar
   lib/borlandxml.jar
   lib/commons-l
  ang-1.0.jar
   lib/crimson.jar

How can I get rid of the empty row and avoid the hard new line?
