Error when trying to input multiple Ant prefix attribute in gradle script

Problem No such property: prefix for class: org.gradle.api.task.bundling.War_Decorated. I am trying to convert my ant script to Gradle but I am stuck at the zipfileset with the prefix attribute.

Ant Script

<war destfile="${dist.dir}/${warname}.war" update="true" >
    <manifest>
        <attribute name="Implementation-Vendor" value="place" />
        <attribute name="Implementation-Version" value="${label}" />
        <attribute name="Interface-Version" value="${Interface-Version}" />
        <attribute name="Implementation-Title" value="Telescope WS" />
        <attribute name="Compiled-By" value="${user.name}" />
        <attribute name="Compiled-On" value="${TODAY}" />
        <attribute name="Sealed" value="false" />
    </manifest>

    <zipfileset dir="src/com/place/telescope" prefix="WEB-INF/classes/com/place/telescope">
        <include name="*hello.xml" />
        <include name ="weknow-${world}.jar
    </zipfileset>

Gradle Script

   war {
   manifest {
    attributes ('Implementation-Vendor': 'Place',
    'Implementation-Version': "$label",
    'Interface-Version': project.'Interface-Version',
    'Implementation-Title': 'Telescope WS',
    'Compiled-By': 'user.name',
    'Compiled-On': 'TODAY',
    'Sealed': 'false')

   }
archiveName 'MANIFEST.MF'
//dependsOn 'zipAllfileset'
 }
war.manifest.writeTo('dist/warname.war/')
fileset(dir: 'src/com/place/telescope', includes: 'hello.xml, 'weknow-' + project.'world' + 'jar',
    prefix: 'WEB-INF/classes/com/place/telescope')`
