Hello I have successfully managed to run AutoSPARQL on my machine. The mail adress in the readme http://localhost:8080/ gives an html page with the following error message (But this is not my issue)

Error 404 - Not Found.
No context on this server matched or handled this request.
Contexts known to this server are:

I could however get the app running on http://localhost:8080/autosparql-lite/. However, when I choose a query from those suggested , eg:films starring Brad Pitt on dbpedia, the app says " Running... " and stays idle forever. I checked the terminal, and found the following error message , Any clues please ???

SPARQLEndpointMetrics relies on an external SOLR index that does not contain this data anymore.

In general, AutoSPARQL is a research prototype that is not maintained anymore and does not work correctly anymore due to changing snapshot dependencies and external services. If you want to get it to run again, you need to debug the source code. If you chose to take this route we would be delighted if you could share your fixes via a pull request.
