    Upgrade your Java to version 1.6 or later.

    Hmm, I'm not too sure what is going on here. We have a CI job that is set to publish this jar I think. Anyhow, probably the best thing to do is to build the time series forecasting package and then install the jar in your local mvn/ivy cache.

    Cheers,
    Mark.

    thanks Mark. I install timeseries forecast package manually and its works.
    now i have error in path data (pathData = "C:\\Users\\prakhar.shrivastava\\workspace\\ForecastModeling"
    its gave me error java.io.FileNotFoundException: C:\Users\prakhar.shrivastava\workspace\ForecastModeling.

    and i confuse in forecaster.setFieldsToForecast(). because i used Jpa to fetch the data from database. Should i give here datamodel name or data access modifer name.
