Environment:

sesame-2.4.0

Description

I have only imported the rio packages that I require using Maven, however, there are errors printed for the missing packages, ie, Trig and Trix. These should be warnings or informational at most, as the package still operates properly without the missing parser factories.

See below for a stack trace.

I would prefer not to have to filter these messages, as I would like to see Sesame/Rio errors in my logs if they are legitimate.

These errors are printed because your classpath contains a file that specifies the availability of this parser. Please make sure that the file(s) called /META-INF/services/org.openrdf.rio.RDFParserFactory only specify the parsers that are available.

Thanks for that knowledge!

I went and looked at my imported files and found the file in the common-1.2.jar file that is published by https://github.com/joshsh/sesametools

I am using that package for its rdf-json parser and writer, and didn't realise that it was including other parser regitry entries that it doesn't provide. I have filed a bug with that project to remove the unnecessary files.

It is a very neat way of publishing this information by the way!
