force downloadLicenses when clean (#2104) (#2247)

when clean task is mentioned the lazyDownloadLicenses gets called before the clean runs, but during clean the license-dependency.xml also gets removed hence the checkLicenses.doLast fails. added the check to force downloadLicenses when clean task is going to run
