Hide Clojure REPL from command-tab application switcher via lein, command line, or emacs

When starting a clojure app via lein on osx, the java coffee cup icon shows in the dock/app switcher. How can this be hidden when:

  • running from the command line
  • running a repl from the command line
  • running from emacs via cider

It all revolves around the environmental variable that gets "-Dapple.awt.UIElement=true" to the running process.

From the command line, before running the target program:

`export JVM_OPTS="-Dapple.awt.UIElement=true"`

Same as above, added to your lein project.clj file:

:jvm-opts ["-Dapple.awt.UIElement=true"]

From emacs, running a REPL via cider. Add the following to your .emacs file.

(setenv "LEIN_JVM_OPTS" "-Dapple.awt.UIElement=true")
