create jar with custom manifest with multiple libraries in classpath

Issue

I'm trying to create a jar from my eclipse and in order to be able to use the external .jars, I'm using this manifest with multiple .jars in the classpath:

Manifest-Version: 1.0
Sealed: true
Main-Class: src.BatchTester
Class-Path: . P:/Tools/xstream/1.4.2/lib/kxml2-2.3.0.jar P:/Tools/xstream/1.4.2/lib/xstream-1.4.2.jar P:/Tools/StringTemplate/4.0.5/lib/antlr-3.3-complete.jar P:/Tools/StringTemplate/4.0.5/lib/ST-4.0.5.jar P:/Tools/Jdbc/lib/sqljdbc4.jar

Obviously if I don't put the libraries in the classpath the following error appears:

java.lang.NoClassDefFoundError: com/thoughtworks/xstream/XStream

But when I put them in the classpath the error changes to:

java.lang.NoClassDefFoundError: src/BatchTester

So it seemps that it can't found my main class. I've tryed with several possibilities in the classpath, like adding or removing . to the classpath, but can't make it work.

Any idea of how can I solve this???

Thanks for your time and effort,

PS: After creating the .jar the classpath in the manifest inside looks like:

Class-Path: . P:/Tools/xstream/1.4.2/lib/kxml2-2.3.0.jar P:/Tools/xstr
 eam/1.4.2/lib/xstream-1.4.2.jar P:/Tools/StringTemplate/4.0.5/lib/ant
 lr-3.3-complete.jar P:/Tools/StringTemplate/4.0.5/lib/ST-4.0.5.jar P:
 /Tools/Jdbc/lib/sqljdbc4.jar 

with new lines and spaces, but even after changing it to the "right" format, I got the same problems.

PS2: I know that with some plugins like Fat-Jar you can make it work, but I don't want to insert more data than needed in my .jar

Solution

Finally I've copied all the libs into the /lib folder and add them into the .jar with an ant target since seems to be OK with the IT guys (because it is a small application).

Here is the ant(in case is useful for someone):

<?xml version="1.0" encoding="UTF-8"?>
<project name="BatchTester" default="compile" basedir=".">
    <property name="external" value="lib/external-libs.jar"/>
    <target name="compile">
        <javac srcdir="jav"
               source="1.6"
        />
        <echo>Creating jar File</echo>
        <!--create a new .jar with all the external jars in /lib-->
        <jar jarfile="${external}">
            <zipgroupfileset dir="lib/">
                <include name="**/*.jar"/>
            </zipgroupfileset>
        </jar>
        <!--<sleep seconds="1"/>-->
        <!--create .jar file-->
        <jar jarfile="BatchTester.jar" index="true" filesetmanifest="mergewithoutmain">
            <fileset dir=".">
                <include name="**/jav/**/*.class"/>
                <exclude name="**/jav/**/*.java"/>
            </fileset>
            <zipfileset src="${external}">
                <exclude name="META-INF/*.SF"/>
            </zipfileset>
            <manifest>
                <attribute name="Main-Class" value="jav.BatchTester"/>
            </manifest>
        </jar>
        <!--delete previously created extern .jar-->
        <delete file="${external}"/>
    </target>
</project>
