I trying to set up a java IDE on my mac running el capitan, however the installer that I have found requires me to install a separate IDE for c/c++ and java (Eclipse Neon). What options does eclipse have that would me to have one IDE for multiple languages?
Eclipse is a platform. Install either. Then run it. Click "Help > Install New Software ..." then in the "Work with" drop down select "Neon - http://download.eclipse.org/releases/neon/", then expand "Programming Languages" and select "C/C++" or "Java" as desired.
And you can switch modes with "Window > Perspective > Open Perspective > Other"
Just try to open a
*.cpp file in your IDE, Eclipse will then prompt for possible plugins to install. This include the
Eclipse C/C++ IDE plugins, that is the "official" one from Eclipse community.
