Hello world 
I’ve downloaded LT
git clone --depth 5 GitHub - languagetool-org/languagetool: Style and Grammar Checker for 25+ Languages
and then I’ve compiled the dev version, in order to have access to ngram feats
cd languagetool/languagetool-dev; mvn clean package -DskipTests
I have made a csv file with bigrams for a language and I want to make use of it in LT, as per
But I get errors
java -cp ./languagetool/languagetool-dev/target/languagetool-dev-6.4-SNAPSHOT.jar org.languagetool.dev.bigdata.FrequencyIndexCreator lucene ./input/2 ./output/2grams
but still not there
