Exception: java.lang.NoSuchFieldError: TYPE #17

Trying to run the mappings by code I get the following error. When I try to run this by command line with the same mapping file everything runs fine


java.lang.NoSuchFieldError: TYPE

the code that throws this error is the following:

        StdRMLEngine engine = new StdRMLEngine();

        StdRMLMappingFactory  mappingFactory = new StdRMLMappingFactory();
        RMLDocRetrieval mapDocRetrieval = new RMLDocRetrieval();
        String mppingDocLocation = Resources.getResource("carbonMapping.ttl").toString().replace("file:","");
        Repository repository =
                mapDocRetrieval.getMappingDoc(mppingDocLocation, RDFFormat.TURTLE);

        RMLMapping maping = mappingFactory.extractRMLMapping(repository);

        Map<String, String> parameters = new HashMap<>();
        String [] exeTriplesMap = new String[0];

        RMLDataset dataset = new StdRMLDataset(false);
        return engine.runRMLMapping(dataset, maping, null, null, null);

The same error happens on both master and extensions-fno branch.

can you try with full path for the mappingDocLocation and let us know?

andimou commented 7 years ago

ah but no.. it seems like it reads the map doc

andimou commented 7 years ago

can you try return engine.runRMLMapping(dataset, maping, "", null, null);?

jimkont commented 7 years ago

looks like in extensions-fno it works now, sorry! the submodules were not initialized correctly before

jimkont commented 7 years ago

hmm, it runs now without a fail but it returns an empty RDF file and the following exception
