Generate manifest class-path from <classpath> in Ant
Solution 1:
<path id="build.classpath">
<fileset dir="${basedir}">
<include name="lib/*.jar"/>
</fileset>
</path>
<pathconvert property="manifest.classpath" pathsep=" ">
<path refid="build.classpath"/>
<mapper>
<chainedmapper>
<flattenmapper/>
<globmapper from="*.jar" to="lib/*.jar"/>
</chainedmapper>
</mapper>
</pathconvert>
<target depends="compile" name="buildjar">
<jar jarfile="${basedir}/${test.jar}">
<fileset dir="${build}" />
<manifest>
<attribute name="Main-Class" value="com.mycompany.TestMain"/>
<attribute name="Class-Path" value="${manifest.classpath}"/>
</manifest>
</jar>
</target>

Solution 2:
Assuming Ant 1.7 or above, you can use the manifestclasspath task.
<path id="dep.runtime">
<fileset dir="./lib">
<include name="**/*.jar" />
</fileset>
</path>
<property name="dep_cp" value="${toString:dep.runtime}" />
<target name="default">
<manifestclasspath property="manifest_cp" jarfile="myjar.jar">
<classpath refid="dep.runtime" />
</manifestclasspath>
<echo message="Build Classpath: ${dep_cp}" />
<echo message="Manifest Classpath: ${manifest_cp}" />
</target>
Solution 3:
If you just want a common subpath shared between two (or more) paths, that is easy to do:
<path id="lib.path>
<fileset dir="lib">
<include name="forms-1.2.0.jar"/>
<include name="BrowserLauncher.jar"/>
</fileset>
</path>
<path id="project.class.path">
<pathelement location="build"/>
<path refid="lib.path"/>
</path>
<property name="jar.class.path" refid="lib.path"/>
EDIT Sorry, I misunderstood the question. Try this:
<property name="jar.class.path" value="lib/forms-1.2.0.jar lib/BrowserLauncher.jar"/>
<path id="project.class.path">
<pathelement location="build"/>
<fileset dir="." includes="${jar.class.path}"/>
</path>
Solution 4:
You can use <pathconvert> to convert a path (which can contain a fileset) into a plain string. You'll likely need to <echo> that string to a file, use either <replace> or <replaceregexp> to chop the leading path bits, then finally use <loadfile> to load the manipulated string into the final property.
Implementation left as an exercise to the reader.
