(Crossposting note: I've now posted this question at http://stackoverflow.com/questions/34564716/jrubyj... too, after not having received any response here) I'm on Windows, with JRuby 1.7.23 (but I think this doesn't matter for this question). My project directory has the following subdirectories: - javas (contains the Java source files) - rubies (contains the Ruby source files) - gem (contains my gems) That is, my gem directory is *not* a standard place. I install the gems with jruby -S gem install GEMNAME --install-dir ./gem and set the environment variable GEM_HOME to my ./gem directory If I had a pure JRuby application, it would find my installed gems. The problem is that it is a mixed Java application. I'm creating my jar file like this: jar cvfm app.jar manifest.mf -C . Main.class javas\*.class rubies gem\gems\* which, as I can see, nicely packs my gems into the jar file. When I run my application with java -cp c:\jruby\jruby.jar;app.jar Main I get an exception when I require one of my installed gems, which is not surprising, because GEM_HOME doesn't have any meaning when the application is run from the jar file, does it? What is the best approach in this case? Should I explicitly manipulate the $LOAD_PATH, and if yes, how? ================================================ Problem solved! For the solution, have a look at the Stackoverflow link mentioned above.
