npm_cache_clean does not work anymore since npm5

[damnms]

Task :my-project-webclient:npm_cache_clean FAILED npm ERR! As of npm@5, the npm cache self-heals from corruption issues and data extracted from the cache is guaranteed to be valid. If you want to make sure everything is consistent, use 'npm cache verify' instead. npm ERR! npm ERR! If you're sure you want to delete the entire cache, rerun this command with --force.

Is there any way to configure that task to add the "--force" option? Unfortunately i must provide backward compatibility, so i can not simply skip that delete cache task.
