How to use a customized dictionary in Language Tool

Thank you so much. I removed 1.7 and specified the JAVA_HOME for 1.8. It built successfully for the command line:

$ mvn package -DskipTests -DoutputDirectory=“myBuild/”

The result is a set of jar files in the myBuild folder, which I was able to import now in my project (in Eclipse).

Further question, if possible: how to use the lemmatizer of the new LT in Java code?
I managed to successfully import the following:

import org.languagetool.JLanguageTool;
import org.languagetool.language.English;

However, how to call the Lemmatizer? I cannot find any class with a relevant name in these jars. I tried creating first an instance of the LT:
JLanguageTool lt = new JLanguageTool(new English());
But how to replace the line below (that used the previous LT directly from the Maven repository, through the DKPro framework) to point to the new lemmatizer?
lemmatize = createEngineDescription( LanguageToolLemmatizer.class );

Thank you again for all your help!
