Manifest doesn't support the "file" attribute

I am using the following ant section to generate the manifest file so that I can run the program
by using the generated jar file. 

	<target name="compress" description="Compression target" depends="compile">
		
		<jar destfile="${output}/MyClient.jar" basedir="${output}">
			<include name="**/*.*" />
			
			<manifest file="${output}/MANIFEST.MF">
				<attribute name="Built-By" value="${user.name}" />
				<attribute name="Built-On" value="${timestamp.isoformat}" />
				<attribute name="Main-Class" value="com.swing.client.MainFrame" />
				<attribute name="Build" value="${build.number}" />
				<attribute name="Date" value="${TODAY}" />
			</manifest>
		</jar>
	</target>
I am getting the following error message when I run the ant script.

C:\Java\AntBuildProject\ Class org.apache.tools.ant.taskdefs.Manifest doesn't support the "file"
attribute.

How can I fix this? TIA.

Delete the file attribute, you don't need it.

When the manifest task is used as a nested element of the Jar task, 
the "file" and "mode" attributes must be removed as the location and 
name of a manifest file in a jar file is fixed and cannot be changed, 
so you don't need to specify the output location.

According to the manual:

"The manifest nested element allows the manifest for
the Jar file to be provided inline in the build file
rather than in an external file. This element is
identical to the manifest task, but the file and mode
attributes must be omitted."
