问题
I have the following code:
(ns test-hook.core)
(defn -main []
(.addShutdownHook (Runtime/getRuntime) (Thread. #(println "shutdown")))
(println "start")
(doseq [i (range 1 6)]
(Thread/sleep 1000)
(println i)))
and the following project.clj
(defproject test-hook "1.0.0-SNAPSHOT"
:aot :all
:main test-hook.core
:description "FIXME: write description"
:dependencies [[org.clojure/clojure "1.2.0"]])
when I run it with "lein run" the shutdown hook only gets executed on normal program execution, not when receiving SIGINT (Ctrl-C)
the same code when ran outside of lein successfully executes the shutdown hook even when receiving SIGINT.
how can I have the shutdown hook executed when running from lein and aborting with Ctrl-C?
回答1:
Have you tried running it with trampoline?
lein trampoline run
Seems to work for me.
AFAIK "lein trampoline" doesn't nest the JVM, so your Ctrl-C isn't caught by leiningen, but by your code.
