      I am trying to set it up nexj on my macOS machine, I am currently trying to install the Ruby plugin, and I keep getting errors, such as:

      com.nexjsystems.nexjstudio” was unable to instantiate class “nexj.eclipse.views.RepEditorNavigator

      Could not initialize class nexj.eclipse.model.repositoryManagement.BaseRepositoryCollection

      I have the same version set up on my windows machine and works just fine, I was just wondering if it’s possible to set up on a macOS.

      Although we don’t certify the plugin and installer on MacOS, we do have some community members that run using this environment.  I spoke with Bryan Sachdeva, who has done this, and he will share his experiences with you after verifying his setup tonight.  He will post some info by tomorrow.

      Hi Rafael,

      As Ed mentioned, it’s possible – and I’ve even done some development and testing from mac, but it isn’t a certified stack. Installation of NexJ Studio using the studio_installer.jnlp file from the p2 repository will not work, unfortunately.

      For Ruby (i.e. version 12.x of NexJ Studio), you’ll want to download Eclipse Mars 1 IDE For Java Developers (https://www.eclipse.org/downloads/packages/release/Mars/1). You may need to install JRE 6 and 7 for this to launch (https://support.apple.com/kb/dl1572?locale=en_CA and http://www.oracle.com/technetwork/java/javase/downloads/java-archive-downloads-javase7-521261.html). Once you have Eclipse running, you can use the existing P2 install method by going to Help -> Install New Software and then entering the location of your P2 site for the plugin installer. After you restart Eclipse, NexJ studio should be available from Window -> Perspective -> Open Perspectives -> Other…

      If you do not have a P2 site set-up, then you can unzip the contents of the .zip file for the plugin. To do this in Mac OS, you’ll need to navigate to the Eclipse app icon in Finder, then right-click on it, and select Show Package Contents. You can then navigate to Contents -> Eclipse, and unzip the plugin files there. Before NexJ studio will work, you will need to manually install GEF. To do that, go to Help -> Install New Software and select “Mars …”. Search for and install “Graphical Editing Framework GEF SDK” and “Graphical Editing Framework Zest Visualization Toolkit SDK”. After you restart Eclipse, NexJ studio should be available from Window -> Perspective -> Open Perspectives -> Other…

      Hope that helps! Let us know if you still encounter any issues.

      Happy Modelling!
