Build Error due to ant classpath.

I get the following error when running a build which makes OSLC calls using Apache HTTP Client:

java.lang.NoSuchMethodError: org/apache/http/conn/ssl/SSLSocketFactory.<init>(Ljavax/net/ssl/SSLContext;Lorg/apache/http/conn/ssl/X509HostnameVerifier;)

Now this Ant Script runs fine when run locally outside of the Jazz Build Engine. I did a google search which led me to believe that the problem is due to an instance of the Apache Http Client library included in the Jazz Build Engine. Unfortunately setting includeantruntime="false" does not seem to be doing the trick.

Any advice would be greatly appreciated.

My Classpath:

<path id="com.ibm.swg.cip.data.classpath">
        <pathelement location="bin" />
        <pathelement location="libraries/db2jcc_license_cu.jar" />
        <pathelement location="libraries/db2jcc.jar" />
        <pathelement location="libraries/db2jcc4.jar" />

        <pathelement location="libraries/commons-logging-1.1.1.jar" />
    </path>

The ant target where the exception is thrown:

<target name="AllTests" depends="build">
        <mkdir dir="${junit.output.dir}" />
        <junit fork="no" printsummary="withOutAndErr" includeantruntime="false">
            <formatter type="xml" />
            <test name="com.ibm.cip.swg.data.test.AllTests" outfile="result"/>
            <classpath refid="com.ibm.swg.cip.data.classpath" />
        </junit>
        <junitLogPublisher filepath="result.xml"  buildResultUUID="${buildResultUUID}" repositoryAddress="${repositoryAddress}" userId="${userId}" password="${password}" /> 

    </target>
