I imported some jar files from apache/POI(the Java API for Microsoft Documents) into a solution. Then I included to my language the java_stubs in was needed to generate files.
But I've got an error telling me that an ancestor is not visible in this module. I tried to find if there was a dependecies between classes I'm using and other jar from apache, but nothing fix my problem.
Did you have an idee about what's wrong ?
