Best practice to use Eclipse IDE

Create clojure project. Let default configuration.

Now go to core.clj and create run configuration --> give a name --> apply and run

Next right click on cire.clj --> clojure --> load file in RAPL

Now make sure you can run your code.

Create a clojure project and create a clojure file to put in following code.

(get {:a 1 :b 2 [{}] 3} :a)

Create run configuration: RUN --> Edit Configurations.. --> '+' --> Clojure REPL --> LOCAL --> Apply (let all default)

Now run your run-configuration. The REPL-Sever should start now showing something like that:

Starting nREPL server...
Connecting to local nREPL server...
Clojure 1.8.0
nREPL server started on port 38550 on host 127.0.0.1

Now mark a line or right-click on the file and select:

REPL --> Load file in REPL / send '...' to REPL to execute the code.
