I use Intellij Idea.
Java-classes use .txt files which are placed in folder where .java files are situated. 
I created .jar file with maven and pom.xml. But there are no .txt in .jar file. 
How to add them there?
UPDATED:
I have such structure src/main/java/Project-name/ for .java files. And src/main/resources/for .txt files. Within .java files I access files as ../../resources/filename.xml and all works fine. But .jar-files created with maven  says:
Unable to open "../../resources/filename.xml" 
How correctly should I declare filenames?
