jar files included in build.xml is not taken in the classpath in the declared order

Question

This is my build.xml file. I have included the jar files in the specific order which I require (This is important. If not I will get package is sealed exception). But the classpath I get is:

[echo] Classpath is C:\Users\aswathy_krishnan\eclipse-workspace\MerckDemo\lib\iwats-scripting-library-v1.9.jar;C:\Users\aswathy_krishnan\eclipse-workspace\MerckDemo\lib\jcommander-1.27.jar;C:\Users\aswathy_krishnan\eclipse-workspace\MerckDemo\lib\json-20160810.jar;C:\Users\aswathy_krishnan\eclipse-workspace\MerckDemo\lib\tessract-wrapper.jar;C:\Users\aswathy_krishnan\eclipse-workspace\MerckDemo\lib\testng-6.11.jar

What am I doing wrong? How can I make sure my tesseract wrapper is always the first jar to be included? I am a beginner in ANT.

    </project>

I tried running the test via testNG and it works fine.This is because I gave priority to my tesseract jar in order and export tab of buildpath. Please help.

fileset does not result in an ordered collection. To order the elements in your classpath definition, you should use multiple <pathelement ...> instead:

<path id="build.classpath">
    <pathelement location="${lib}/tessract-wrapper.jar"/>
    <pathelement location="${lib}/testng-6.11.jar"/>
    <pathelement location="${lib}/iwats-scripting-library-v1.9.jar"/>
    <pathelement location="${lib}/json-20160810.jar"/>
    <pathelement location="${lib}/jcommander-1.27.jar"/>
</path>
