creating a local cube with xmla and ascmd in sql server 2012

I am trying to create a local cube through an SSIS task. With earlier version of sql server I usedascmd. I could not find ascmd for sql server 2012, so I usedinvoke-ascmd. However when I use the -Server option to point to the local cube, it errors out with the message:

Warning WarningCode="-1055653884" Description="Errors in the met adata manager. Either the database with the ID of '' does not exist in the server with the ID of '\LocalCube', or the user does not have permissions to access the object." Source="Microsoft SQL Server 2012 Analysis Services"
