Thanks, Jim. But with-out-str only works for output to *out*(stdout), but not *err*(stderr). A quick test is: (with-out-str (try (throw (Exception. "Hello")) (catch Exception e (.printStackTrace e)))) which it returns: "" but the stack trace still gets printed out: java.lang.Exception: Hello at user$eval2774$fn__2775.invoke(NO_SOURCE_FILE:1) at user$eval2774.invoke(NO_SOURCE_FILE:1) at clojure.lang.Compiler.eval(Compiler.java:6511) at clojure.lang.Compiler.eval(Compiler.java:6477) at clojure.core$eval.invoke(core.clj:2797) at clojure.main$repl$read_eval_print__6405.invoke(main.clj:245) at clojure.main$repl$fn__6410.invoke(main.clj:266) at clojure.main$repl.doInvoke(main.clj:266) at clojure.lang.RestFn.invoke(RestFn.java:1096) at clojure.tools.nrepl.middleware.interruptible_eval$evaluate$fn__1402.invoke(interruptible_eval.clj:57) at clojure.lang.AFn.applyToHelper(AFn.java:159) at clojure.lang.AFn.applyTo(AFn.java:151) at clojure.core$apply.invoke(core.clj:601) at clojure.core$with_bindings_STAR_.doInvoke(core.clj:1771) at clojure.lang.RestFn.invoke(RestFn.java:425) at clojure.tools.nrepl.middleware.interruptible_eval$evaluate.invoke(interruptible_eval.clj:42) at clojure.tools.nrepl.middleware.interruptible_eval$interruptible_eval$fn__1443$fn__1445.invoke(interruptible_eval.clj:170) at clojure.core$comp$fn__4034.invoke(core.clj:2278) at clojure.tools.nrepl.middleware.interruptible_eval$run_next$fn__1436.invoke(interruptible_eval.clj:137) at clojure.lang.AFn.run(AFn.java:24) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1110) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:603) at java.lang.Thread.run(Thread.java:722
