Manifest file

[Eric Dantec <er...@laposte.net>]

Hi all,

I use Ant 1.4.3 and I have an issue while running a build.xml file.

I have a project called "type". In this directory there are :
 - *.java files
 - build.xml file
 - MANIFEST.MF file

I want to create a jar file with the class files and the updated MANIFEST.MF.
The jar is created and it contains :
 - the class files
 - the original MANIFEST.MF file
 - and : a directory called "meta-inf" that contains the new MANIFEST.MF

What I want to do is updating the existing manifest file, not creating a new one in a different directory.
So here is the code of my build file :

<target name="jar" depends="main">
    <jar destfile="${JARDIR}/type.jar" basedir=".">
        <fileset dir="${CLASSDIR}" includes="com/lawson/rdtech/${ant.project.name}/*.class" />
        <fileset dir="${SRCDIR}" includes="com/lawson/rdtech/${ant.project.name}/LEAF_NODE" />
        <manifest file="MANIFEST.MF" mode="update">
            <attribute name="Built-By" value="${user.name}"/>
            <section name="com/lawson/rdtech/type">
                <attribute name="Specification-Title" value="whatever"/>
                <attribute name="Specification-Version" value="whatever"/>
                <attribute name="Specification-Vendor" value="whatever"/>
                <attribute name="Implementation-Version" value="whatever"/> 
                <attribute name="Implementation-Vendor" value="whatever"/>
            </section>
        </manifest>
    </jar>
</target>

When I run it, I have an error that says that "Class org.apache.tools.ant.taskdefs.Manifest doesn't support the 'file' attribute".
So I can I fix that? Is there another mean to update an existing manifest file?

Thanks,

Eric

You are using a <manifest> element embedded in a <jar> task. This is designed 
to generate a manifest inline without requiring a manifest file.

If you want to manipulate manifest files you use the <manifest> task. i.e. 
don't stick it in the <jar> task. It will then accept a file attribute and 
you can update the manifest file. You can use the resulting file in a jar 
using the <jar> tasks manifest attribute.
